Ok you GM guys, I have the motor all tanked and mag checked for the Riv. Everything looks good so far. Heads are being done with hardened seats and new valves.

Question 1. This is gonna be my long distance super cruizer, anybody got a clue how much camshaft these things like?? I'm fabbing a set of headers for it, any ideas on tube and collector size?

Question 2. I would like to put EFI on the motor for good driveability, any suggestions on a good throttle body unit and electronics package to use??? Idea #2 was to fab an intake for it and make it a multi-port, again how about electronics??? Been studying a bit on the Holley system, any opinions???

Thanks for the help, and Streets, ain't no way I'm gonna put a chebbie in the Riv!!! I am going to put a Blue Oval in Jackie's Vette, though.
