Default Nostalgia

Was thinking of the 402 block as a replacement and to build from there.However, I am thinking I'd like to keep the original engine.Can you give me some ideas of HP and TQ with the progression on parts as follows. Consider them to be additive.

A. Cam (still streetable), long tube LG headers, ARP headers.

B. Forged pistons, rods, maybe crank

C. 90mm Throttle body and intake

D. Appropriate size injectors for the above

E. What am I missing??
Somewhat complicated but thanks for your help.

I assume your talking about your C5, if so C5 tech would be a better place to post this, but ill tel you what i can, lg headers will give you 20-30hp, a streetable cam should give you about the same.I dont think forged pistons will help much unless you plan on running boost or nitrous, i think therye mostly used for strength, not power. and thats all i know, try C5 tech
