I'm going to pro build a Nova SS (I know I know it's not a vette...), the car will be built with the less BS posible (power things, A/C, etc) looking at the weight savings.
I need an advice on engine parts to use, it must be a 450-600 HP, possibly with alu heads.
SB or BB?
Dart M blk? (I had it in my 406 SB 575hp engine in my C3 and never ever gave signs of probs...
Intake and carbs?
Forged internals?
Will a new Muncie 4 speed M22/M23 hold the power and torque? I don't want to go exotic with 5 or 6 speeds trans.
Thanks in advance for your precios comments and advices...
This much power in a Nova, probably not a cruise around town car. Yeah we do engines, but the chevelle guys, yellow bullet, etc are more all out 8000 rpm for 9 seconds type people.
A well built fuel injected SB 427 will get you right at 600+ hp or a injected 454 would be around the same hp. How much money do you want to spend? A 632 BB with fuel injection can get you to 850-1000+ hp. Pick your poison and go from there. I would not push a stock M22 to far past 600 hp/tq. There are people building up-graded M22s that can handle the higher hp/tq numbers for around $2700.

Cost per HP, small blocks don't compete with BBC. Over 600 427 ci. Could cost $12,000. On the other hand it only takes a hotter cam and headers to make a650 hp 502
Im gonna quit building a new car, the task is too meaty for the time I have available, Im probably buying one of these two 69 Camaros with BB I went to see in Holland last week...Prices are pretty high but for fully restored muscle cars these are the kind of price levels you need to face..
If I were you I would build a 421. The 3.875 stroke crank makes for a better, stronger piston and you will never notice the loss of torque. With the right heads, the 421 could make 575 streetable horsepower very easily with a hydraulic roller cam.
I used to build these with a Dart 227 CNC head but there are a couple of better options now......one of them is the AFR Competition CNC head......but my 227 CNC stuff would make 108% VE...so the AFR should improve on that. I used a ported Brodix HV1 intake or the Wilson Super Victor.......the intake is very important at this level as you are trying to move a LOT of air through smallish runners.
The Little M Dart block is an anvil.
Make sure you grind the cam on a .900 base circle to clear the rods. H-beam rods are standard issue here along with a 4340 crank. The Callies Dragonslayer and Scat/Eagle are offshore forgings but are damn near indestructible.
Finish it off with a 950 HP Holley and good to go.
