it all depends on what you want to do? restore? street/strip? the good thing about small block chevys is the availability of parts and the interchanging of them. guess by your name 72 ? is it a chevelle? my 56 chev truck is a easy restore but i had full intentions when i bought it to put a small block in it and lower it some.dare to be different.

It's actually a chev half ton. I am also putting air bags under it, if the rules will allow me to race it. The primary use for the truck will just be to cruise, and some trips to the strip.

the choice of using a 307 is based on year, check the #'s out to see what you have. I have a 1970 307 which has 882 heads,flat tops,and buy the books is listed as being 300HP. One more thing to do is check out pricing on parts, pistons are alot more $ for a 307 than other SB's. But if you do research on 307 build ups you will find out that there are plenty of big hp 307's out there.

the bore of a 307 is the same as that of a 283, and the stroke is the same as a 327. I didn't realize that 283 pistons are that expensive, thanks.

Dear 72, save your money and "DON'T" spend a cent on the 307. Find a 400 or 350 that needs to be rebuilt and go in that direction. Stay with the bigger cubes and longer stroke which will create more torque which is needed to accelerate a heavy mass much quicker. The better bang for the buck is to go big. In the Big Block World, people build 454's, not 396's. -- All the best, Kevin

i don't really want a gas eating "ground pounding" big block. I also don't want a "warmed over" 350. I want a high winding, super flying, and import eating small block. It isn't hard to make 500 horses with 454 cubes, but building a high horsepower, reliable, streetable small block is a little harder. Then again why work at anything, when money will buy you what you want, oh yeah, people with out money. P.S. where am i gonna pick up a cheap, good BB?

Trublu 72, you misunderstood my point about the BBC engine. I was trying to use it as a comparision between building a 307 or a 400 cid smallblock Chevy. When you say you want a highwinding SBC that means high RPM which means $$$$ to build and maintain the valvetrain along with a good singleplane intake, a good cylinder head, a healthy bottom end and oiling system. Steep rear gears and a fairly high stall convertor would also play an important part. Sure it can be done, but it can get damm pricey. What does your truck weigh with you onboard and what ET do you want to turn? ---- Kevin

i have a good intake, a decent set of heads that i have ported, roller rockers that i got for a steal, huge pushrods, the engine already has a steel crank in it, i've 2 converters, a vega cut to 1800, and another cut to 3000. I have most of the gear to build the engine, that's why i think that i'll do it that way. The truck is a short wheel base 72 half ton, don't know what it weighs, but it came from the factory with 4.11 posi. which should be enough, using my 26" slicks. Hoping to run in the 13's maybe, what do ya think?

I think it can be done, but how easy it's gonna be is another question. A 307 might not be the best choice for a performance build-up, but it'd sure be different. I say go for it if that's what you want to do.

Tose old 307's don't work bad, but you'd likely get better mileage with a BBC! -Chris
