Place your bets. More like 15-17 seconds. What did you base this theory on? Around here your cheapest bet would be to buy a used race motor.

actual engine built and put in a 67 longbed chevy. it dynoed 345 hp and 365 tq add your 125 wet shot and your 450-495 (it dynoed 3 times with 3 completely different nos results) at the flexplate.yea 15-17 second times if you forget 3rd gear

I like how i can buy parts for te 305, and LATER add them to the built sbc, either 350-400

Sorry, But I call BS on this... using the wallace calculator you need to have about 500 HP at the Crank... especially with the tires spinning...
I don't mean to be rude... but I just don't buy it... been around Drag racing and engines too long....

My truck had basically the same setup when I got it.. 355 with the Comp 270H Cam, Edelbrock Performer Aluminum Heads, edelbrock RPM intake, Edelbrock Carb, 2400 RPM Converter and 3.73 gears, and it ran 15.1 at about 92 MPH, and it is a shortbed (Lighter) and it hooked up.

the calculator is displayed as Rear wheel Horsepower as below.


Your HP is 378.05 computed from your vehicle weight of 4500 pounds and ET of 13.3 seconds

[Chris Guthro]

If the truck weighs 4600lbs, it says it would take roughly 332hp to the wheels to get 13.98

Ok I guess if you use higher dollar parts and its not possible it cant be possible with low dollar parts..... its cool with me, Ive built a few motors too and i know what works and what doesn't. I'm just offering my experience for a new trucker if you don't like it don't read it. If anyone is from sacramento about 20 years ago the primer grey chevy with the 5 spoke etII wheels with the centers painted blue...... at sac raceway every wednesday and friday night for 2 years. if you were there you couldn't forget it. yea i did a disk brake swap way back then with the 71 rear to match

You can but the heads are small chamber(58cc) and the runners are to small for 6500 rpm on a bigger motor. Everything else you buy can be used on a 350-400 you would most likely want a bigger cam the 268h is as big as you would want to go on that 305.

Low Dollar or MEGA Dollar.... not possible with those parts you specified, unless that truck weighed 3000 Lbs

Ok, I figured it was the same truck. All my buddies make fun of my slow daily 305 and when we saw this a light bulb went off in everyone's head. They laugh now but I'm searching for a t78 to put on this 5.3 that's laying in my garage. I put a Z06 cam and a ls1 intake with everything else stock. That'll be my setup till I need more speed

Here's a link to Mark Jones' site.

Now he builds big blocks that the members at Team Chevelle rave about. I haven't used his products, don't know him but his cheapest motor at $4995 pan to carb would get you in the low 13's easily. Who doesn't like a big block?

"467 517 HP 564 TQ
9.1 compression
Excellent muscle car engine replacement, excellent vacuum, very street friendly
Dyno tested"

[JBRAVO383]

I have a 85 shortbed that weighs right at 4k with me in it. It has a crate 383 stroker, 650 Holley vacuum secondary's, forged internals. 10.0:1 compression that made 462 horse and 465 ft lbs at the crank.. paid right around 6k from URE engines for the "turnkey" which i still had to buy a starter and a water pump because the one i got was for a serpentine and not a v-belt set up(spun backwards).. The trans is a th400 built for nitrous, manual valve body, and 3600 nitrous stall that flashes at 3200 on a foot brake ( i don't run nitrous). That was with the truck when i bought the roller.. the rearend is just a truck 10 bolt, eaton posi and 4.10 gears. Traction bars and m/t e/t street tires. i bought the truck completely done as a roller with everything but an engine, for 2300 which is a complete steal!!! I think as is right now i have right at about 10k into it. My first street/strip build.

I ran a 13.26 at 99 with a 1.8 60' The tires were to big as i was running at 30x12.50 .. havent had a chance to get to a track since i pun 28x10.50s on it, but im sure they will get me at a higher trap speed and i get lower my ET. Also need a little carb tune.

If i could do it all over again, i would have bought an ls1, did heads and cam intake and exhaust, and a small shot of nitrous and probably had the same results, and still got 15 or better mpgs and not a whopping 5 .. But i'm not sure if this helps any decision making. but just make sure you completely explore all of your options before you start spending money.

[rayfinseats]

SO ANYWAY... Build it and run it and then tell us how you did. I knew a guy that had a blown 454 in a vega TUBBED and went 12's. And there are stock class 305 Firebirds running 10's. Go figure. Also there is a second or so difference between California and Iowa due to altitude. I drag raced for ever. 3 camaros, a chevelle, brothers chevelle, nephews dual turbo 80 malibu.
