I installed a crate motor GM 454 COMPLETE with everything in an SS454 Chev pickup. Carb, starter, etc. It was NOT a 'drop in'. I was surprised how many modifications I had to make, including cutting off 'ears' on the front of the intake manifold for clearance for the accessories. Grinding, drilling, custom fitting, whew, so much for a 'complete engine' being a 'drop in'.
DISCLAIMER: That was a customers truck, I'd rather push a Ford than drive a Chevy.
