I am looking for a 302 ci engine pm if you have one for sale
matt

 

a chevy 302 or a ford 302? if your looking for a chevy 302 that is anywhere near running conditition, be ready to put out BIG money....they didn't make many of them and people are REALLY proud of them.

 

could easily build a chevy one out of any 350 block

i dont see the point though

if need a ford one then i have one, a nice running 87 FI 5.0L still in car strong runmner $300 takes it and whole car too

The cheaper way may be to buy a 327 block and put a 283 crank in it. If I am not mistaken that will give you your fast and high revving 302.

The 327 blocks aren't too expensive and neither are the 283 cranks.

i have a forged 283 crank, also have a block. won't ask why you'd want to go to the trouble and expense to build such a small engine.

 

Small journal 327 block and 283 shaft will make the 302. Pistons are expensive but not to bad. 302 would be a good street engine. most people have never driven a 302. they are a great high rpm engine. we ran them in our old C-gas dragster. shifted at 10,000 rpms. thats why people like them. by the way would take a 302 over a 305 any day.

 

dont forget the 55-57 265 cranks

and that there was a 350 in 68



327 1968-69 4.001 (2.3" main) 2 bolt
350 1968-88 4.001 (2.3" main) 2 bolt

302 1968-69 4.001 (2.45" main) 4 bolt
350 1968-96 4.001 (2.45" main) 4 bolt

Jeff that is correct the only difference is that the homemade 302 you mentioned only has a 2 bolt main. The Stock Chevrolet ones had a 4 bolt main.

I actually have a Stock 302 out of a 1968 Z/28. It comes with the Muncie M-22 4 speed trans and the vin plate off the car all numbers matching. Picked it up about a year ago and was going to build a '68 Z/28 (not a clone because everything would be right, but still kind of a clone).

I would get rid of it but I would need to get around $3000 for the set-up (That's what I paid for it). Engine is said to run (never started it) but I had a guy offer me 2,000 just for the block and heads (even if they needed to be rebuilt) at a swap meet this summer.

But let me know if your interested, I know it's alot but these engines are super rare.

Well the 2 or 4 bolt main of the 302 would depend on year. All 302's made prior to 69 had 2 bolt mains. And yes all 327's were 2 bolt mains.

I don't really get into the 2 or 4 bolt main thing. I have a 454 +.060 in my chevelle. It is a 2 bolt main but I used ARP studs and my rods are ARP wavelok pro series and the engine dynoed at 607hp at 6800 rpm. I pull the engine every winter and check it over and prior to this year (haven't pulled it yet) not had any crank walk yet.

Now if I were to spray the engine I may want to consider having my block machined for splayed 4 bolt main caps. But for now I don't need any spray.

With a 302 the only thing that would make me worry a bit about 2 bolts is the RPM that a 302 can turn. I think I would probably want a 4 bolt main if I were going to turn in excess of 8000 RPM. But there too, a block can be drilled and tapped for splayed caps and will actually be considerably stronger.

By the way Camarofreak406, selling or re-using a VIN tag off of any car other than the car it originally came on is a felony.

while the 302 is a cool motor and has the ability to spin to high rpms, the heads in order to flow all that air at that engine speed would be EXTREMELY expensive. i just don't see it being very cost effective, especially since the kid looking for one is 14. (yep, i read those profiles we all have to fill out.)

anyway, cubic inches equals easy horsepower. i built a 305 and ran 13.0's with it after LOTS of tuning, i'll be going out and setting a new best with my 350 right outta the box with no tuning, simply because of more cubic inches.

if your going to spend money building a high rev motor, do it with more cubes and build a 377.

 

with the Heads now a days its easy to get a 302 to turn 10,000. The same head for a 400 turning 8000 will breath better for a 302. 100 inches smaller is alot of difference in the head breathing. I wouldnt build a 302. I have all the parts to build a few of them but im building a 406. the 2 bold vs 4 bolt is kind of mute if the engine isnt getting sprayed and not really running over 6500 rpms. My 427 ( 2 bolt) in my last car I shifted at 6500 to 7000. making 600hp and never had a problem. but like notmuch I pulled it every winter and freshened it.

 

well, with a motor that could possibly spin to 10grand, i'd want top start with a 2 bolt motor and use a splayed cap anyway.

 

Why build a small inch motor and have the hassle of keeping the thing @ 8000RPM to make power when you can just build a big thumper that will put out just as much grunt @ 2500RPM?

It never ceases to amaze me how many people get a hardon for a chev 302!


If 302s are your thing have fun but i think money would be alot better spent on a bigger inch motor.

 

Its just a personal preference thing........I like high-revving motors too, they are a blast..it explains the popularity of the ****-burners and little cars now-days..........but building a 10000 rpm V-8 costs some big bucks...........and with a fairly heavy g3n-3 car, the big cubes would seem to be more practical on the street, if that is where he plans on running...........

 

It never ceases to amaze me how many people get a hardon for a chev 302!


Must be you never had the experience they were tempermental and not very tractable on the street . BUT with the 140 off road cam big headers and nothing less than 4.88 gears were more fun than a monkey in a mile of grapevine

 

speeking as a man who knows, If you cant find a 302, do this and you will love it.
Get a 283 boar it to the stand size of a 327(there is more then enough meat in the block to do this and you wont run hot eather)
this will give you what they call a 301. There is a book out there call chey 265 283 that will explane everything.
I got the book off ebay cant remember the seller tho
But anyway I love the high reving fast shifiting that you get with this set up not to mention I jump out of the hole on a lot of 350.
have fun good luck and HAPPY HOLIDAYS!!!

 

The best and cheapest way to go is very simple. Find yourself a late model 350 one piece rear main seal block, either 2 or 4 bolt main(your choice, but the 4 bolt #638 cast is a great choice). Then head down to the junkyard and ask for an L99 265 cu inch motor, they don't seem to be to desireable, so you may not pay a whole lot. These were in the 94-96 Caprice, Impala, and other B-body cars, and possibly in some light duty 1/2 ton trucks. The motor will have 4.3L stamped on it. Inside this "gem" you will find a 3.00 inch stroke crank with 2.45 main journal and the 2.10 inch rod journals you need. The connecting Rods are also "special" in that they are 5.940 inches center to center giving you a 1.98:1 rod/stroke ratio. These rods are also special powder coated ones and will fit a variety of standard 350 , 4 inch bore pistons to make your combinations endless and inexpensive.

In addition, the late model 302 build as fore mentioned will utilize a roller cam and lifters. Can't you hear it screaming already !!!!!

 

I have to admit that idea for a roller 302 could get fun

 

My pops has a 302 in a 72 nova . has the old gm performance angle plug heads with 2.05 valves silly wild cam lightweight valvetrain.victor manifold,dual feed 850. That car is a beast !!! you will **** yourself the first time you take a sbc to 9,000+ rpm and it's still pulling like a mule !!! and jesus and joseph hold on if your a powersifter like myself cause your getting all kinds of out of shape when you shift. SOB now I may have to build one just for fun. anyone got a short bed 2wd s-10 laying around
