I built a LS1 up to 430HP, one issue i had was the small diameter LS1 MAF. I went to an 6.0 L truck MAF and it made a huge difference above 4500 RPM. I already put a larger TB before I changed the MAF.

Using the card. Not really worried about to much at this point. I've done my homework from mapping the turbo all the way down pipe size and length. Only thing I don't like is the 3 inch coming out of the turbo. I wanted 4 inch until a certain point where the exhaust cools enough to go back down to 3inch to keep a raspy exhaust tone but I've already stuffed it full and run out of room.

If your running an LS1 set up you can upgrade to an LS6 style PVC system by replacing the valley cover.

Just did this on my 85 with LS1. Switched to the LS6 breather, and modified the valve cover. Was easy, will update my thread (in sig) when I get a chance...

Hi COPO,

Are you going to do a complete back-half?

My 92 is almost completed. I went with a 9" Alum center-Strange Housing with wishbone locator.

Good Luck! Looking forward to seeing your finished result.

Regards,
Steve

No plans on a full back half due to what I plan on doing.
Have a thread on yours.
