Default Curious as to what I will put down

I have a 2002 Camaro Z28 m6. When the car was dyno'd last it put down 343whp and 358 wtq with a MTI clear lid, LPP long tubes, LPP ORY and SLP dual/dual catback. (this was on a Dyno Jet 248x at nrg tech racing here in NY)

When I bought the car I changed the catback to a Magnaflow 3inch catback w/ resonator welded in the straight pipe. I am currently in the process of adding a 225/229 .580/.590 114+4 LSA cam and TSP Stage 1 LS6 heads. Any idea what I will put down on the same dyno jet?

That cam being medium sized, it isn't going to give you huge peak gains compared to a donkey dick cam but you should def pick up quite a bit of midrange power with that cam. If I had to guess I would say you should be in the ballpark of 385ish rwhp on the same dyno.

That cam is fairly similar to a 224 cam and some of those will pull 400 to the wheels but they are just exceptionally good running motors anyway. I've seen similar setups range anywhere from 370hp all the way to 400hp... so I chose an average in the middle from what I've seen.

411rwhp here with unported 243 heads but I had them milled .020" for 11:1 compression and I did my own 5 angle valve job. Running a custom BRE 224 cam, ebay headers, slp dual dual with 3.5" cutout, LS7 clutch, LS6 intake and my own tuning with hp tuners / wideband. I would be sad if you put down less than 420 rwhp with ported LS6 heads. I ported up my own fast 78 intake to a 85 mm with a ported 85mm throttle body and am adding an underdrive pulley. I will be heading back to the dyno soon but I am hoping for 430 rwhp and 400 rwtq.

I completely overlooked the LS6 heads haha. You should be just over the 400hp mark with the heads. Reading owned me lol. My guess was based on thinking you were still using stock LS1 heads and being cam only.

You should see about 400 with that setup. Good luck!
