[THEFERMANATOR]

I know mine is 155 on 3 differrent guages, and I've checked a few other 140 LOOPERS and they all checked out at 135-145 on my guage. The V-4 90 degree loopers don't have idle reliefs like teh V-6's have, so they have alot higher compression than there bigger counterparts. I know the 94+ V-6's get 110-120, but the V-4 should be a bit higher. Mine ran at 110, but I never could get it to idle right until I rebuilt it and got my compression back up to 140(then I opened it back up and ported it a bit and decked teh heads and got it up to 155, still ran great on 87 octane gas though at 19 degrees of timing).
