Just replaced my 5.7/ 350 and need some help working out the kinks.
I had to replace the starboard motor and I’m trying to work out some kinks... First two things I need to address are
I can’t get the new motor to spin more than 3,400 RPM- It’s a 5.7/ 350 Vortech motor. I purchased this new from Michigan Motorz and its hooked up to my Alpha 1 drive.
The motor idles smoothly at 600-700 RPM. So dose that rule out a timeing issue?

Few things will limit RPM, Fuel flow, exhaust restriction, and poor timing. If timing checks out do a fuel filter change. Is this an EFI motor? Take a look at throttle rigging. You may be pushing the throttle but the carb or AFM may not be corresponding with input.
