Motor Confusion...
I've read several posts talking about the 305 V6 engines in these old trucks. I thought 305 was a V8! In fact I know it is! Me and my pal broke into "triple digit speed" in his '92 Camaro RS last night. I'd be suprised to think that a V6 could drive as hard as
So is he confused about the number of cylinders in his car or are there 305 six cylinders AND eight cylinders? Speakin' of which, he has an "extra" 305 laying around and has no use for it. Do you think this would be an improvement to a 250 inline six?

Re: Motor Confusion...
The 305 V/6 engines are GMC only engines.

Re: Motor Confusion...
Both, 305 sbc had eight small cylinders, while a GMC 305 v-6 has 6 large cylinders. If you want a huge v-6 they also made a 351.

Re: Motor Confusion...
I just swapped a perfectly good 250/6 for a 305 just because I had one sitting around, but since I hate 305's so much I know I'll live to regret it, I already do as a matter of fact.. if your gonna' move up to a V8, move up to one worth your time. I say that because the 305 is limited in it's performance output, although, if you don't plan to do any HotRodding and you don't wish to push beyond 325 HP, a 305 is fine.

the only v6 after the early 60 were the 2.8, 4.3, and the 4gen camaro 3.8. i wouldnt be surprised if he had a 4.3 that would hit 100. the 2.8 and 4.3 were not tpi motors and its very obvious if that what youve got. |

Re: Motor Confusion...
Nah, you got it wrong. He already knew his 305 was a V8. I just find it suprising that a 305 came in both 6 and 8 cylinders and that someone had screwed up somewhere.
Haha! Fatman! That was so funny! .....You're lucky "State of Denial" isn't on a map. As far as a 305 smallblock being inferior to the 305 V6, that must explain why I see so many 305 V6's around.

Re: Motor Confusion...
the 305 v6 is a old and only a old motor, there are no new 305v6's, there is no comparison between them. your talking about a large bore/stroke small carbed old tech motor againts a roller small stroke efi better flowing castings new tech stuff, both have there place but neither one is worth more than scrap to 99% of the population.
if you have a 305 v6 you pull it out for a v8, if you have a 305 v8 you pull it out for a 350. |

Re: Motor Confusion...
I know the speech man. The old motor was for hauling and this Camaro V8 is more for speed yada yada yada. BUT, as you also mentioned, they each have their own special place.
That one dude was saying how much better the 305 six cylinder model wwas SO MUCH better than the eight cylinder one. Evidently not true as I think we would still be seeing a lot more today.

Re: Motor Confusion...
Try explaining to the pimple faced little brat at Checkers that you have a 1972 CHEVROLET 307. One day I finally turned and walked out of the store when the kid was trying to tell me it was a Pontiac or Olds 307.

Re: Motor Confusion...
Ok heres a good comparison for you.
A 305 V-6, depending on which model, made any where from 260 to 280 ft lbs of torque at 1600rpm or under. A 92 Camaro RS 5.0l (305) makes 255 ft lbs at 2400rpm. Torque is what a truck needs to move when it pulls or hauls anything. This old technology made that power down low enough to allow the truck to pull. A carb swap alone probably allows that motor to make 275-300 ft lbs. I'm don't own either one of these motors and quite frankly I don't want to. The 305 V6 can not rev that high because of it's design and the 305 V8 does not have enough displacement to make the power I eventually want. No where here do I see a post where he someone say that the v-6s are SO MUCH better then the v8s. So I don't know who sent you a PM or deleted their comment, but each engine has their own application. One motor is not decisively better then the other. The v6 will out pull and most likely live longer if taken care of, but the v8 will smoke the v6 when its not pulling. Mike

Re: Motor Confusion...
I owned an '86 camaro Z28 with a 305. Piece of **** motor. Would never own or install another one in any vehicle I own. The car ran/drove like a top, but was gutless, I was almost embarassed it had Z28 badges on the car (my '86 toyota truck with a 4 cylinder 5 speed would break triple digits too.). I would keep your six popper over the 305, you'll be happier. If you're going to drop some coin on a V-8 swap go with a 350, a 305 isn't worth it.

Re: Motor Confusion...
Try finding parts for a 305 V6, thats the main problem with those engines. Otherwise, they are good for pulling stumps. I used to own a '78 Monte and a '78 Impala, both had 305 V8's. I found they are good motors to put in a car. Good for regular driving, reasonable gas mileage etc.

Re: Motor Confusion...
why is everyone infatuated with 350's i've seen 283's and 327's that would run circles around "built" 350's

Re: Motor Confusion...
The only thing a GMC V6 is good for is a farm truck that'll never have to go past 50mph. Granted, I love these motor's to death, they are wicked cool and have oodles of torque, but a V8 is much more practical on the street it's not even funny. Think, when I get a 350 in my truck, I'll be able to go past 55mph without wondering if the motor will blow up.

Re: Motor Confusion...
In 1991 I bought a new S-10 with the 4.3 and a 5 speed, one night my friend, who was in a z/28, was sitting in front of me at a 4 way intersection and nail it when he took-off. I gave chase, caught him and squalled 3rd gear as I passed his front fender. I even hesitated 2-3 seconds before I left the intersection.

Re: Motor Confusion...
Fatman stated that the 305 V8 was a "wimpy" motor compared to the 305 V6 (he's obviously full of crap there). Why in the Hell would I want a 305 V6? I ain't a farmer. SOOOO, it does better at high speeds then the 6er. I told ya man, I know all that low end torque junk.
People probably prefer 350's cus there just about the most 'universal' motor out there. AND they're still in production. 283's were out by 1968. Quote:

Re: Motor Confusion...
The 305 was practicly an indestructable engine. It was perfect for the day, and was one of the hardest working engines of it's time period.
They can go over 55... you need better gears. A 350 in that truck will rev at the EXACT SAME RPM. the 3.8 was not a camaro engine, it is a buick engine out of the early 70's, maybe even the late 60's IIRC. The anemic 305 V-8 is not a bad engine, it just doesn't belong in a hot rod (camaro) nor a real work truck. if you just drive your car/truck to get from A to B, then a 305 will be fine. If you expect horse power or torque, look elsewhere. The 283 and 327 were great motors, however, to say a built 283/327 running circles around a 350... well, apples to oranges... make that a built 350 and your argument doesn't hold any water. Those 2 smaller engines were phased out becouse they needed higher RPMs to make the power that was needed. With the EPA requirements, and the CAFE requirements, they could not be made to work properly. BOTH 305's are great motors. As for swapping an inline for a 305, you'll probably be disapointed, but hey, try it, you can always fix your mistake with a 350, or going back to the inline. |

Re: Motor Confusion...
The 302, 307, 327, 350 and 400 are nearly identical. All else being equal -- there is no substitute for cubic inches. 350s and 400s make the best hot rod motors and can very reasonably be punched out to about 430 cubic inches.
I really wouldn't fuss with a 283 unless you have a resto that started with one. They can be tweaked up but they have an annoying tendency to chuck robs if they are pushed too hard. The "305" is really just an updated 283. The more recent 5 liter motor, though of the same displacement as the "305" is a whole different animal. The large bore v6 motors are really interesting but if you really want torque then listen to Andy (I mean about the inline, though a Caddy BB is no slouch... lol) If you want torque *and* high end power -- nothing beats a rat. In the end -- nothing is "better" until you define your application. A 302 with twin carbs makes a fine stock car motor but it won't haul a trailer up hill.

Re: Motor Confusion...
If you want a Camaro motor in your truck,put one in.Don`t knock one of the best truck motors ever built.At least not on a vintage GM truck site.These "are" trucks and believe it or not,some people actually use these things to pull and haul heavy things that a Camaro won`t do.In that way,the 305 is "wimpy".That first V6 went into medium duty trucks as well.Speed was not the focus,getting all that stuff up the road was.In vintage speed circles,the GMC V6s got warmed over and supercharged and were capable of awesome quick ETs.These trucks outweigh a Camaro by a good bit.Your results with,even,an H.O.305 will not be the same.
You are not comparing apples to apples,the arguement is pointless.But,you did say,"I`d be surprised a V6 could drive as hard as..."I assume you would say 305/V8.Let`s assume you meant any V8 to give you a stronger arguement.Ever heard about the Buick Grand Nationals or GSXs?They eat big blocks and spit them out.Capeesh? The GMC V6s were phased-out because of emmissions and fuel economy concerns.Also,buyer mentality..."why not get a V8 if the V6 gets the same mileage?"The world`s moving faster than back then,too.Not such a good thing IMHO. I wouldn`t want a 305(V8),but wouldn`t stop anyone else.If I looked at buying a truck that had a 305 V8,I`d look at it as a truck w/o a motor.I`d prolly not be able to sell-off the motor for any considerable sum."Why run a 305 when 350s are so abundant?"If I was focused on high-performance,Why not go "BIGGER"???!!!! The 305V6 is a gas motor that pulls like a diesel.

Re: Motor Confusion...
Now that it has been explained, do you have anymore doubts?
In whatever hole you are at you're welcome to come to the "state of denial" (PA) and bring your buddy's super-duper triple digit speed camaro along then we can see who's the one full of crap, how about it? we'll start by pulling 1 ton and we'll go from there, and if you ain't no farmer what the hell are you doing with a truck?

Andy I know a 350 will turn up the same RPM in my truck, but the 305 V6 is really screaming at 2700rpm, almost redlined, where a 350 would be in its cruising rpm, IMO. I could be wrong though. That may be screaming in a 350, too. |

Re: Motor Confusion...
my bad... seen way too many ppl make the mistake, thinking that since a small block will rev better than a 6, and get all bent out of shape to discover the same screaming sensation with the replacement engine. 2700 is starting to get up there a little bit. (I go screaming down the freeway well into the 3ooo to 35oo RPM range every morning...even higher if I'm in a hurry)
