Re: Building my 327
By rebuild you mean?
Do you want to machine the block and everything?
Deck it for a good quench depending on what gasket you want, throw in some decent pistons, shoot for around 10:1, double humps can make a lot of power depending on how far you go with them.
I know of a lot of strong running 327's with 9.6:1-10:1, headers, good dual plane intake, smaller holley carb, a good old 268 comp cam, they will run stripes around bigger motors.
My setup is a .040" 327, around 10.8:2, comp cams 286H-10, 190cc 58cc chamber 2.02/1.60 valves, runs strong, it's a dog with 3.08's and a manual trans, but runs very well. Throw in some lower gears with a good stall with the glide, or as said before get a th-350 or a 700r-4 or 200r-4 if you can find them and it will run even better.
The high gears and 3.08's are going to hold you back, they really limit how much cam and so on you can run with that motor.
