How many HP should I be making?
Yes I know this is a silly question, but anyone care to guess?
My car has a Vortex rammer airbox and airbridge, LS-6 intake, Z06 Ti catback, Magnaflow X-pipe and I will be installing stock LS-6 heads, 218/224-
565/555 115 LCA cam and maybe shorty headers or Z06 extrude honed
manifolds. Ti retainers, Manley valve springs, Manley hardened pushrods.
I know the last 3 don't count for HP gains..lol.
:seeya

Re: How many HP should I be making? (Scubanme)
I’ve never heard of a ZO6 that didn’t dyno at least 350 bone stock and most do around 360+. Since what you have is more than a bone stock ZO6 than you will have more rwhp than that. The Vortex stuff has to be worth at least 10 rwhp and the cam at least 15 rwhp over the ZO6 cam especially if you add LS6 injectors (which you probably need now anyway) and a good tune. That adds up to 380 give or take the way I see it.

I think you will put down about 360-365 RWHP. Forget about the shorty headers, they aren't any better than your stock manifolds. Install long tube headers or leave the stock manifolds don't waste your money on shorty's.

99 frc , not a zo6...... :yesnod:
However. look at how it compares to the LS6 motor in a ZO6. As far as the parts that make horsepower goes everything in his planned motor is the same or better with the possible exception of the injectors. Therefore his output should be better than a bone stock ZO6. Significantly better if he goes with the ZO6 injectors and gets a good tune :cheers:

"As far as the parts that make horsepower goes everything in his planned motor is the same or better with the possible exception of the injectors."
I agree with this statement, and at the 380rwhp projected level the stock injectors should be fine also.
