Thanks for the help guys. The engine spec sheet shows this engine having LT1 (1970 vette) springs. The cam spec is 212/222 @50, 435/460lift. I may need to check for spring damage? While adjusting the lash I didnt notice any out of the ordinary sounds except a minimal amount of lifter noise in #6 when warmed up and above 2200rpm. The fuel pump is factory stock. The fuel lines are 3\8 rubber from pump to carb with wix canister filter inline. I havent paid enough attention to oil psi during shut down, it usually idles about 15psi and 55 (hot) 60 (cold) at cruise. I may need more instruction on the dist. power leads? When I replaced the module, The wiring terminals clip crumbled in my hands and just installed the ends individually to the module. This should be ok since no further malfunction, and that was part of T&E. I'm no expert on these conversions but I see a power block of some kind on the fire wall close to the dist. that has a larger battery source terminaled to it. This is a constant power source with the switch turned off. Is this what I,m looking for?

On the drive home last night I noticed the failure seems to occur when opening the secondaries. It will cruise at 4000 with primaries. Trying to accel. with WOT (secondary) it stalls and surges. No trouble with WOT from idle to 3800-4000.
