Mines right around 135 across the board.
Yours sounds on the low side and that's a pretty good spread.

Thanks guys. Couldn't remember. Had one years ago all tuned with fast pipes. This one done up in s chassis very clean. Was playing with jetting and it has dial a jets was bouncing all over on egts so thinking compression down and its acting funky.

So thats stock compression? This sled has between.065-.070 squish. Has wiseco pistons and 4 dot gasket. Cylinders look good. Looks like doo does not offer pistons anymore or base gaskets.

Oh yes Tom. I found pistons and gaskets, not sure why this one so low. Pistons and cylinder looksgreat. Maybe never got a good seat. Will redo see where it goes. I hope that cures it.
