I have an E-M with a 383 small block chevy with Edelbrock EFI and Richmond 5 speed. I was just dynoed at 425hp. The car is very driveable and responsive.
By the way, I was running at 40psi
oil pressure until today when it dropped to 20 psi. Does anyone have a clue why this occurred. Could it be that the sending unit went bad. The car has just been completed and has less than 600 miles on it.
