Edelbrock TES for dual cat setup (yeah, not best, but easier install with cats and existing SLP cat-back)

Edelbrock TPI base

ASM large tube runners

Clean up/port stock plenum

1.5:1 roller rockers (Crane gold??)

Cam with 206-212 intake duration w/ corresponding dual pattern exhaust approx 10 deg more and relatively low lift to work with bone stock L98 cast iron heads

Again, some of my earlier posts clearly say not building a race car, just nice gain over stock.

Already have UD pulley set, K&Ns, AFPR, SLP chip, Accel SuperCoil, and 22# Bosch injectors.

What type of HP increase estimate??

Anything way out of balance in this setup?

 

Must be on the right track, I guess...

 

I don't see anything particularly wrong with what you're proposing (although DIY PROM tuning would make more sense than an off-the-shelf chip), I just don't have any idea how to put a number to the answer.
