327 bored over 30 ZZ3 cam with trick flow heads and Eldebrock Runners and intake.. this is just a thought if anyone wants to add ideas please do....

Why a 327, it laying around?

I'd pick a different cam, and the 327 (RPM motor) and the TPI (anti RPM intake) wont get along together so well although it will work.

 

I think I heard of someone doing well with a 327 and a miniram intake, if thats in your budget.

 

I picked 327 because everyone has a 350 and I want something different...

There's a reason that most people prefer 350's..

89 iroc-z 305 tbi
k&n filtercharger, open element air filter. nuffin' else

 

yeah so he could get much better power out of that then the 305, but i would recommend doing this....
1) getting an aftermarket TPI intake baseplate and porting it to the max siameasing the runner.

2) get SLP semi-sieameased runner and fully port those

3) Port the plenum, runners and baseplate and head to match to the gasket. that should give you some more Rs. Then try to get a cam and head combo that make there power at a little lower RPM, you should have a good performer then.

 

Then get a 350 or a 400 and tell everyone that its a 327

 

So what alot of you guys are telling me is to stay away from a 327?? why is that?

Personally, I would build a 383 if you're wanting something different from the 350. Or look into that new 427 small block . By using that cam and a TPI setup you will ruin the high-revving performance 327s are so fondly remembered for. If you're going to run a 327, do it right, and run a carb or miniram. IMO, that cam won't be quite enough for it either.

I think the 327 is a cool idea but don't rape it with a TPI setup. Just my $0.02.

Some guy I know has a 327 in his z28 and that thing is the fastest third gen I've ever seen but he still prefers 350s. 327s need to rev higher to make the same power as 350s so he has this overly-huge cam in it which makes it barely streetable.

 

Why stay away from a 327? Well are you looking to make some power or not? There's a phrase that dates back before my time, probably even before my dads time that he taught me, "There ain't no replacement for displacement!" In other words, Money+Displacement=Power, or this formula can be shortened to money=power since more displacement will generally cost more (although I'm not sure if that holds true trying to build a 327)
If you really want to be different, you could de-stroke a 400...Some say this makes for faster and higher revving motors which is great for horsepower, but probably not as good for the low end torque. Another option would be to grab the buick 3.8 Turbo motor It's all up to what you want to do, and your budget.
Good luck

Someday I want to build a twin-turbo 327. I think it would work well since a 327 will rev. Hell why not make it a roller 327? Dude you could chirp the tires into overdrive!
