Re: Non stock 327 buildups (Daffy2)
How different? Blowers, turbos, nitrous, Weber carb setups, tunnel rams, cross rams? Blocks painted hot pink? Fake fur on the air cleaner lid? Real fur?
OK, I'm done now. Seriously, what kind of build are you thinking of?
I have mine set up to look stock but pumping out 20+% more power at the wheels, through exhaust manifolds. But I doubt that is what you are looking for.

Re: Non stock 327 buildups (L79vette)
Probably jsut a 4 barrel or 3 X 2. I'm really interested in mixing parts, like a 283 crank and 327 block to make a hot 302. Strokers are made all the time from 350's, but what are the possibilities from a 327? I have a good '67 block thats been decked, but not bored, so I've got a starter piece.

Short stroke & less cubes only makes power at very high RPM. Not fun for the street. Racers don't do it either unless the rules specify. Go for the most cubes you can get.
Small journal stroker cranks are not readily available, though my engine builder friend tells me you can get a custom billet steel crank for $2000 with any specs you want.

The only reason GM made the 302 was to be able to compete their new Camaro in the TransAm racing series, which had a (I think) 305 ci limit. If the rules had allowed, they would have used the biggest engine they had.
Daffy, I can understand your interest in doing something that's different from the norm but consider why the "norm" became a norm. In this case, longer strokes in SB's became popular because they resulted in more power than a shorter stroke. Also, by being able to make that higher power at a lower rpm, reliability and drivability are increased. If you're intent on not being a part of the 350/383 crowd, build your 327 as a 327 and buy some 302 badges for it. With everything else being equal, it'll make more power and no one but you will know the difference.

Daffy, if you are willing to spend some money to be different, you can get some awesome-looking injection setups and other induction exotica.
Let's back up a bit again. How much budget do you have for this engine buildup? What kind of car, what use, what gears and tranny?
You can make 400+ HP from a 327 with good street manners, if you buy aftermarket heads like AFR or Dart. Dunno what your goals are, though.

Re: Non stock 327 buildups (Daffy2)
Got any pics of the nostalgia fuel induction setups?I would like to see something like that for a future project of mine.I want to build a chevy 302 too.I plan to use a 3inch L99 crank from a 94 265 and a 350 block.

Re: Non stock 327 buildups (blackLS1)
http://www.inglese.com - Weber carburetion
http://www.hilborn.com - 8-port injection setups. Recently released EFI versions.
Offenhauser still makes a copy of the Z28 racing crossram manifold.
Tunnel rams abound. Edelbrock makes one with smaller runners specifically for the street.
Roots-type superchargers with 2 4-barrels are readily available too.

Re: Non stock 327 buildups (Daffy2)
Thanks for the many replies. I've been in self enforced quarrantine with a computer virus. Specially interested in a message laying out the specifics of a 383 stroker from a 327 and interesting intake setups. This will develop into a first building experience with my son and I'll post as things develop.

Re: Non stock 327 buildups (Daffy2)
Only a small percentage of 327's were large journal blocks and unless you already have one, I think you'd do better with a 350 block which are much more plentiful. Keep in mind that the difference in displacement between the 327 and 350 was due entirely to their strokes, which would be changed anyway to make a 383. As Wayne posted, small journal stroker cranks can be had but at a much higher price than for a large journal one. You might find an old M/T small journal stroker crank for cheap at a swap meet but a large journal crank would still be much stronger and more rigid.

Re: Non stock 327 buildups (Daffy2)
Any links to info. on unusual 327 buildups ? Either small or large journal blocks. Just want to do something different.
They have lots of other good tech articles too on the left side . :thumbs:
