At a loss here. HPOP oil leak. Change stand pipe and dummy plugs. Stc fitting awhile back. Still having a long start and once warm won't start. Took it to a shop and they faked an air leak test. Here for a job so I can't do it myself. In the process of moving so I need to get it fixed...
I have been looking at these steed speed manifold and a log style. Have yet to see any real data on them. If I could get a set of both for a cheap price I would do the test myself.
Could you not just take the pan off, measure and drill up and then tap down. Or even drill a pilot down and then bring your holes size up from the bottom then tap down.
