I took a 350sbc cris craft reverse engine, changed it into a standard rotation and it ran great. I didnt like the low oil pressure so i installed a new oil pump. When cranking, the gauge now shows good pressure but now it will not start... backfires every now and then but no start whatsoever.
The ONLY thing I changed was the oil pump, so I suspect the problem must be there. Is the oil pump geared differently on the reverse rotation engines? I have checked and rechecked the firing order and timing, and found it to be correct. What would be different between the original oil pump that was installed on the reverse rotation, and a new oil pump that is for standard rotation?
Logic tells me that since it was running fine in the new standard rotation mode with the original pump, the pump is not the issue, but I keep going back to the fact that the only thing I changed was the pump and now it will not start. Any ideas?
