I just bought a used 25K mile Chevy350. The plan is to put it in my 40 Ford pickup. I was told that it's a Targetmaster engine with an RV cam. Although it was done years ago, the guy who installed the cam when the engine was new is still around and I plan to talk to him next week to see what he remembers about it. Here's what I know about it Mexican block Holley 600 CFM square bore electric choke carb Mallory Unilite distributor, mechanical advance Edelbrock Performer intake manifold Edelbrock polished/black fined valve covers It's been decades since I last played with a SBC so I will have a few questions that I hope someone here can answer for me... If I want to run an electric fuel pump, do I need to leave the fuel pump pushrod in the block before I install the block off plate? What is the correct harmonic balancer and flex plate for this engine. What is a good base timing setting?
