Compression Test, Changed carb
By spinnerbait42 - 12/29/2004 6:20:02 PM; IP 138.162.140.45
Hey folks! I broke down & dug out the 'Ol Holley 600 I had in the closet, & I've discovered much better results. Seems it's jetted and cal'ed better 4 my setup and yeilded instant gains in mpg, smoother cold starts & warmups, response, & top end. Jetting seems about right with light tan spark plug readings. When installing the 600 I smacked myself in the back of the head when I realized my vac adv. line had been connected 2 the full vac out of the carb the whole time, DUH! We'll pretend I didn't do that...The compression test, however, seemed sumwut comparable 2 my previous methods. I ended up getting readings of 105 +or- 5psi. Engine @ op temp, all plugs removed, & butterflies fully opened. All cylinders are quite close 2 each other, just seems like a low comp motor guys. Keep in mind it's a new reman from Recon (shouldn't be any defects), the common 8:1 truck heads it came with and the flat-top pistons; who knows wut head gasket they used or that they didn't need 2 true the heads. I elected 2 downgrade to 87 octane, and she maintained the same power, but also gave a slight gain of mpg. Don't see any reason 2 close gap on plugs since there's no miss or fouling, especially w/80,000 volts going 2 them. More input welcome.
This thread, so far...
