awesome sounds from the car man. What size block are you running? Are these PRC 237's by chance? I was considering running the PRC 237's in my 415 iron build. GMMG is my pick on the best catback for our cars. That car roars like a lion dude, I bet it's all out mayhem on the highway!
@cheffy84 This was the stock 5.7 346ci. The heads that r the stage 1 ls6 heads. I have changed the whole car since this vid was taken. The new dyno and track vids on my channel are of the new 408ci, tr6060 trans, and 9in.
Ran it with a slipping clutch, 1.79 60, 12.00 at 120. Was on drag radials. You CAN NOT RUN THE 5.3 STG 2.5 HEADS WITH THE MS4. The only way that this is possible is to flycut the pistons. The ptv clearance is way to close.
how did u like the setup im gonna b doin the same head and cam combo with intake also?? any advice?

No you do not have to flycut the pistons with 5.3 stg 2.5 heads.

I didn't say that you have to fly cut to run just the 5.3 stage 2.5 heads. I said with the MS4, you can't run the these heads.

have you ran it in the 1/4 yet? what kind of prc's you go with? I wanted the ms4 but wasnt sure if the valves would clear with the 5.3 stg 2.5
