Ports are a little smaller but bolted up. Then I took 229 HEI, and thinking one engine is oddfire and the other is even fire I put magnetic pickup out of straight 6 HEI in the distributer. I also used the flex plate off 229 on 350 turbo tranny. Havent gotten it started yet but am beginning to doubt my thinking. Any imput ???
Not sure what ur asking? I know I would have kept the 350. Whats your reasoning for the 4.3?
