Was wondering if anyone from the Springfield Mo area knew about slant sixes that could help troubleshoot my engine not starting?
Brand new rebuilt engine never ran but more than 30 seconds. Engine has 0 vac when starting but engine never starts but tries to. Completely sucks a battery dry every time which I assume is from the engine still being tight since it's never ran long enough to loosen it up. I've got spark and fuel and I'm getting good compression within spec (125-135).
Leak down test was done and it didn't leak so I can assume the valves and rings are doing their job. Here's another odd thing is that every once in a blue moon the car will fire right up. The first time it ran for a few seconds and then acted like someone just turned the key off. Last time it ran and idled perfect for 30 seconds or so and as soon as the throttle was touched it quit and hasn't started since.
I recently took the manifold off and replaced the stock gaskets with REMFLEX gaskets to ensure a leak proof seal to the head, between the manifold and to seal the exhaust flange. Didn't help still no vac at starting. When it ran the last time it was checked for vac leaks and the only leak was from the egr which was fixed other than that none were found. The valves have been done and redone several times.
Engine is 225 with peanut plug head with 40 over pistons and a comp cams 264s. All manifold are ported and head was gasket matched. Has super six setup also with hei setup. I'm at a loss here since everything seems fine. Voltage drops once you try to start it a few times but I've ran a jumper to the coil from the battery to try and ensure full voltage and didn't help. All parts are new except the distributor which is reman. We got number 1 cylinder up and pointed the rotor at it and distributor is has been turned every way it can be but still doesn't start. Anyone got any ideas??
