Well, let me get the lifter companys out from under the bus possibly. Tried a set of Howards and it is worse. Was quite for about 10 miles then one must have colapsed. At least Comps eventually got quite. So we are pulling the intake and dizzy. Will prime motor with a drill while we roll the engine and check each one for prime/hold etc. Also mic the lifter bores as well. I am changing the rockers and shafts as they were used. It will now be new pan to carb. Running out of ideas and funds..... good thing Great Race was cancelled. We were to be in San Antonio today. Jake
