hello this is my first post so i hope i do it right. i recently got a 73 chevy vega with 3 basically complete engines and i am trying to figure out which combinations of these parts will give me the most power. i am going to use a 70's lt1 short block bored 30 over with flat top pistons. i have 2 sets of 487 heads and a set of 624 heads. i have a edelbock 2101 cam, a cam that says nothing but 260 on it and a unknown cam that i believe is a mild rv cam.i have a edelbrock tm1 intake and a stock 350 intake. i have a carter made quadrajet carb and a holly 6210-2 650 cfm carb. Other things on the car to consider are a 2 speed power glide transmition and 4 10 gears, that i will probably be swapping for higher gears. Any thoughts/ideas/opinions that may give me the best results and what kind of hp i can expect? i am also on the search for some vortec heads will that help alot? thanks for the help
