302, 327, or 350????????????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I want to know what you guys think of all of these. I not looking for a power hungry motor enough to have fun and not cost tooo much to drive and or build.......so let me know what you all think

I dont know why but i really like 327's

Kerry P · 10-08-2010, 04:45 PM

Bigger is almost always better in the range you've mentioned. In a heavy vehicle a 383 or 400 or BB will get you moving with much less effort than a 302 or a 327.

People talk about how well the smaller ones rev. A 350 can easily spin to 6000, a forged bottom end will go past 7000.

The parts for 350;s are limitless

llowlife · 10-10-2010, 05:58 PM

I've always had a weakness for 327's too. I built one for a street stock we used to race just to prove that we weren't cheating. Running against 406's we went out and won the first 3 features a 3 different tracks. They are amazing "little" motors. THat being said...Get the longest crankarm you can. either a 350 or 400. A 350 will usually be cheaper to build. If you give me a certain sum of money to build one I will usually take the 350. If you are going mild...go with the 400

292farmer · 10-10-2010, 06:41 PM

truthfully if i had to choose 327, because my dad had one with 400+hp in a nova and it was wicked!!

and theirs alot of 350's out there, so u can be part of the v8 crowd, yet still be different. most(if not all)parts will swap too, if u later want a larger motor.
however our trucks are on the heavier side, so technically a longer stroke is better so 350, or better yet 400.

llowlife · 10-10-2010, 06:49 PM

If you do go 327 try to find a rare large journal crank. 68 I believe, in limited supply.

LostMy65 · 10-21-2010, 01:39 AM

I don't want to hijack this thread, but thought it was close enough, and would lend to the discussion.

So,
If one was going to go with a 350, what's the latest year you'd go with?
Obviously things changed big time in 88/89
So should we stay 87 and older, or what?

Thanks

in a fairly heavy truck I'd want the bigger c.i.d
in a lite car the 327 is a swinding fun machine..
the 302 is a tempermental beast..if built for power..and has no low end..
I'd build a 350 with a aftermarked forged 400 crank for a 383..
vortec heads and a nice somewhat hairy but still mild roller hyd cam..
450hp is easy

LostMy65 · 10-21-2010, 11:31 AM

I think I read somewhere that the 350 changed the way the intake manifold bolted up in 85.
Not sure though.
I'm just thinking I'd prefer a 350 that is physically similar to all the 70's 350s.

INTAKE BOLTS ($) changed in 86 my monty SS is a 86 and is a standard intake but is a 305,and stock down to the belts and hoses
the 350 might have changed in 85
the one piece rear main seal came on line too..in 86 late 85

**71swb4x4** · 10-21-2010, 01:03 PM

I am not certain what year the intake bolts changed but on my 86 Camaro with a 305 and TPI the intake was the same as the old blocks.

mwilliams5891 · 10-21-2010, 01:15 PM

Well thank you everyone for your input! I did buy a 327 short block and I have a 68 350 bored .60 over 2 bolt main in my garage.....so with my c/10 do you guys really think I should not put in the 327? I was going to put vortex heads on it with an Edelbrock intake and carb 500 to 750 CFM havent decided yet. and behind that a Tremec TKO500.....oh and what cam should i look for?

and i am not building a race truck BUT i do enjoy power now and again.

with a stick the 327 will be funn

Small block 421 or 427 and call it a 327. Once its all togeather no one but you will know its actual displacement. The tbi 305 in my Blazer is actualy a 406.

96+ vortec is the best factory sbc block, if it comes with heads, even better
