327

the 327 wont make the torque of your injected vette.
Please do NOT buy the RPM heads!!! Buy afr or dart 180 cc runner heads if you buy AL heads.The GM vortec heads also work well if modified for a decent cam.I love those cars,have fun with it!

327NUT Very nice looking car, you should have a lot of fun with it.

SoCa06Z It was a fun build...got it done in a weekend and just took some time to get the tuning correct. The car pulls much harder now all the way through 6k RPM.

Here are a few pics...

I would get some real hi perf performance cylinder heads with larger 70-72+CC

Then bolt on a Weiand 142 blower.
Try the 268 cam you got. or use a Crane HMV278 (H-278-2)

Set it up for around 7psi boost. 1.95 to 2.10:1 pulley drive ratio.
The carb will need a few minor up grades and jetting and the distributor will need a recurve. to make them blower friendly.
The fuel system on the car will likely need upgradeing for increased flow capacity.

Your low compression street premium pump gas friendly blown 327 Chevy II will kick *** and cruise like a champ.
Big big reliable streetable power and torque.
Tame street-hiway cruising. The 3.73's are just right.

You will slay your fair share of stroker motors, LS motors and big blocks.
Mustangs and foreign stuff will be snack food.
Your stock 327 pistons are fine as long as there is no piston dome.
(flat top or dished) Low compression and reasonable 6-7psi max boost is the key.
I wouldn't discount foriegn stuff so readily, a lot of it is built a lot better than the domestic stuff... and when it comes turbocharged from the factory its usually not too hard to go fast, especialy with irs, awd, adjustable coil overs, etc...

For that matter the domestic stuff is much better than an sbc, slap a few grand into a 98 camaro and it'll walk all over the 327.

500hp is a matter of mail order bolt ons now... and that's from a 4 cylinder.

F-BIRD'88 Then get some sticky street tires. You will need 'em.

Thought that was a given.. Sorry

Got it covered. OH, and a billet small bodied dizzy

You should look into some of these sellers on Ebay that sell header wrap.
I just did a header for my Ram50 and it turned out GREAT. Will lessen underhood temps too!

Ya, I am going to test fit them, then get them coated. Fitment on these cars is a real PITA.

The valve covers I have will work with these, and the kit comes with everything else included. Intake, gaskets, intake bolts, head bolts, rocker arms, etc.

My parts have all been ordered and I am going to run the 268 cam I have in it now. I think this will get me close enough, and won't have to dive further into the motor. I ended up getting the modified Vortecs from Scoggins. I also ordered some long tubes, all new ignition components (Cap, Rotor, advance kit, plugs, wires, etc etc.), fule pressure regulator, and some odds and ends.

I think these upgrades will allow me to enjoy the car much more, and didn't hurt the pocket book too badly. I appreciate all of the feedback and will be posting up more questions as I start getting evetyhing torn apart and put back together.

77amc I'm building a '62 283 that's .060 over and just put in a Comp x268 cam in it.
I also had a shop rebuild my ported Vortec (062) heads and the lift is 477/480 and he said that the springs were slightly higher closed seat pressure (needless to say) open pressure..
You might like to look into that.

Going with roller rockers to help out with the extra tension.
