Have I hit 200hp yet?

I have the following mods:

1) Full 3" exhaust (TES TPI headers, Magnaflow cat and 4th gen catback)
2) Open element with 14x3 K&N
3) Edelbrock Performer TBI Intake
4) Hypercrap Stage 2 (came with car)

I have some other supporting mods, such as cooling items (Edelbrock Victor water pump, Hypertech fan switch, 180 t-stat) and a decent tune up (Bosch Platinum +4s, MSD 8.5 Super Conductors, Blue Streak cap)...

So did I hit an estimated 200 yet, or have I fallen short? I will say one thing...having just added the headers, I gotta say, it snaps my head for the first time ever!

I think the weanie cam is still holding you back in the HP race. I know I managed to put out 181 RWHP/268 RWTQ from a bone stock Cadillac L03 shortblock though. Just bolt-ons and DIY Prom Tuning.

I have no doubt the cam hurts. I'm just wondering where I stand in the food chain at this point. I'd like to think I'm matching/beating an L69, but have nothing to back that up with I know L69s had a better cam, but I think my exhaust makes up for it...maybe?

Re: Have I hit 200hp yet?

It looks like what you have now is great but IMHO the two best things for that ride now is diy prom tuning and a set of 3.42 posi gears..........

Well hello!!! I assume I'll be seeing you in Indy shortly I didn't realize you were a member here...not quite the number of posts you have over at cz28, eh? Since you decided not to sell me your car, I decided to restore another one

Although, right now I'm mad at it...it failed emissions today Time for some Guaranteed to Pass!!! It worked 2 years ago after the EGR had been crapped out for awhile

I'll be there. In fact I just bought an '83 Crossfire Z/28 this week, which I'm planning on taking there. This car needs a new exhaust REAL BAD!
