Thanks for the replies! I'll attempt to address each one.
Sounds like the 110 is a no-go. We only ran it because some people were saying leaded is best. If unleaded 91/93 is okay, then fine by me!
@RustyRatRod You are right on the money, as usual. They are the 4 eyebrow that are not zero deck. Heads are straight out of the box.(no machining)
@RustyRatRod I tested cold compression after we built the engine. All 8 were between 140-148psi.
I tested warm compression just now, (all plugs removed,) cylinders reading between 130-138psi (hopefully not cause for concern!)
@Garrett Ellison Yes, just running the Fel Pro blue head gasket 4.180 in, TRW below deck 4-eyebrow piston.
@Rat Bastid Thank you for bringing this up. Nobody told us about the circuit guard when we were talking to Summit's sales reps. I appreciate this and will order one asap.
I do have a slight doubt in trusting my compression tester. I may buy another to confirm the readings, although I presume this is accurate.
I should have also mentioned it's a 4 speed a833. Sounds like my compression ratio is lower than I had assumed. Are the warm compression test readings above any cause for concern?
Thanks again guys.
