I'm going to be building an old 327 to swap my v6 out for and was wondering
if anyone has any suggestions(besides building a 350). The engine is the 210 hp version so i will want to build it to a higher compression. It is from a 67
camaro so ie should have the smaller bearings. I want this car to be able to hold it's own against ls1's. Any help is apreciated.

Is there some reason you're attached to the 327? Engine parts for a 350 are much cheaper and the added cubes get you more torque. If you're determined to build the 327, the most important thing is good heads and a cam to match. The 210 came with crappy flowing small valve heads.

Wanna hang with bolt-on ls1's, your gonna need at least some good flowing heads(afr 180's or 195's, theres more but thats just off the top of my head), about .500 lift cam, 230*@.05, 4.10 gears posi, 3500 stall converter, and about a 150 shot of dope, some sticky tires and you should be well out in front of most bolt-on ls1 cars.

As for induction an edlebrock rpm air gap and a holley 750 shold do the trick.

That setup should be good for about 400-425 hp, before the juice. But with a that same setup on a 383, with the same brand heads except 200's, would put down about 500+hp.

Oh yea don't forget some decent rods, with arp bolts and forged pistons. You'll want that motor to hold together right.

Maybe a good turbo or supercharger setup could make up for the smaller amount of cubes.

hmm so throw any afr head on a 327 with a cam and a rpm intake = 400-425 hp? I think you might have missed a few details there..

stroker_SS

Did i not specify 180-195cc afr, and the cam lift, and duration, don't know how much more specific i could've gotten.

So instead of criticizing me why not clarify for him

Thanks bud.

I think that's still an unrealistic claim anyway. That's a good idea, but I think it'd be closer to a 350-375Hp engine, on 327 cubes.

All you're realistically planning on re-using here is the block, so you might as well make this a 383. No sense in keeping the cubes small, nothing to be gained there (except going slower).

And don't even try to give me the BS "327's rev higher" or "want to reuse the factory forged crank" lines.

383 cubes and vortec heads is a cheap 375-400HP engine though.

'67 = small journal. Don't see many 3.75" cranks in small journal.

stroker_SS

Couldn't you get a large journal turned down to fit a small journal block though?

The 327 like most other vintage engines is junk in stock form. You can build nice engines out of them for the same price as a 350 provided the crank and rods are useable. For the shortblock I would use ARP fasteners on the rods and get flat top pistons. Then pick a good set of heads and a cam that matches their potential and you will have a nice motor making somewhere near 375hp.

You could. It would be cheaper to buy a 350.

Could sell the block at a premium to someone building a numbers-matching car, and buy a garden variety large journal 350 block with money left over for parts.
