You are getting rather close to that magic number where they won't like you running anymore

Time for a cage

Bigger injectors, so I could shift later. My 42#'ers are beyond maxxed out, so I'm shifting early at 5800 rpm.

Gotta love the 1.59 short time! Last winter I popped a head gasket on the LM7. I bought some new gaskets and was looking for head studs, when I found a 80K mile L33 at a local salvage yard for $900. So I picked it up instead, and got some head studs & gaskets for it. Swapped everything out on a Saturday & Sunday, with all the old goodies in the "new" bullet. I thought I made a thread about it, this was back when I was asking about ring gaps and such.

The tires are M&H Racemaster 275/55R16, which is 28" tall, 10" or so wide.

Get injectors so you can carry it up to 6500ish and you'll MPH and e/t way better IMO...

I know every single Maggie I've ever laid eyes on has seen HUGE gains from very small shots. Put a 30-50 hit through it and HANG ON!!

At 8-9 psi, I can get to about 6400 rpm before I run out of injector. The cam pulls hard to 6400. I've thought about lowering the boost, and adding a shot. I have a HSW wet kit with a Black Mamba nozzle. Picked it up when I felt like I was never gonna get out of the 12's on boost only, and it's just sitting there collecting dust.

I still have a 3.0 pulley, and a 3.4 pulley around here somewhere....
