wats up guys....i have a bit of a dilemma haha...i just bought a 62 chevy nova deuce and i cant decide whether i want to make my .030 over small block a 383 or a 332...i want a very responsive motor that revs fast and is snappy, but i also want cubic inches and torque which i kno this 383 will give...ive driven my buddies 67 elky with the 327/325 h.p. and it sits u in the seat..i love the way it launches, and how responsive the pedal is....i kno that my car ways about 500 to 600 pounds less than the 3200 pound el camino.....is the 332 an *** kicking candidate, or should i just stick with the original 383 plan.......the 383 is going to have these:
10.7:1 comp ratio
kb claimer pistons 5cc flat top
lightweight i-beam eagle rods
5140 cast steel eagle crank
Lunati Bracket Master .500 int./.515 exh 2500-6500 300 duration int. 310 exh
moly rings
World S/R Torquers 2.02/1.60 170cc int. runners 67cc
Edelbrock RPM air-gap 1500-6500
holley 670 street avenger
how does that sound...
please any suggestions will help

If you want to turn that rpm with a 10.7 comp 383 in that 3000 pound car.

I'd go with 6.0 rods, a single pattern 240* actual x 107 LSA cam (roller), beehive springs, 1.6 rockers, and more head for that rpm, and a 750 Mighty Demon (actually I like vac sec for street). And my choice, a clutch shifted stick shift.

That should give you a fat 490 torque curve peak at 4700 and 490 hp peak at 6000.

would i need to use a roller cam, cause theyre expensive, and i love that solid lifter.....plus the 5.7 rods i want to keep the 5.7 rods are rated at 500 h.p.....and i am running a 4-speed

You are giving up torque all across the board with 5.7s.

Flat tappet is ok, you just can't get as much lift.
Remember that solids are measured differently than hydraulics. You want actual "lash" duration and lift figures.

Also with those high pressures on flat tappets, I recommend beehive springs and the break-in procedures that are listed on CompCams web site.
Special oils, etc., Soft break-in springs, run in for 45-60 minutes at 2000-3000 rpm.
(It's on their site)

"I" also recommend getting 4 hours on the engine below 3500 rpm before installing your strong springs, or you could flatten the cam with that much spring on a flat tappet.
