BOSS 302 install in a basic 73 Convert
#11
Does this Boss motor have screw in freeze plugs? If it is a true Boss 302 it will.

UPDATE-- I got the Boss 302 with screwin freese plugs but it only has an Edelbrock 650 4 bbl. If I just do a basic swap with my C-4 tranny an 9" 273 rear end will it work? Improve performance?

I think you will have to change the rear gear to utilize an engine with the torque curve of a Boss 302. You will probably need a higher stall torque converter to work well with it, as well. Boss 302 engines were not delivered with Auto transmissions or gears anywhere as high (numerically low) as what you have-and Ford did it that way for a reason. That combination is not going to perform well.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Consider taking the Boss built Boss 302 and sell it to an actual Boss 302 owner looking for a motor. Then use that money to build a complete driveline that is designed to do what you want!

Good luck.

Hey you have the engine and all the stuff put it in and see what happens. Don't you need a specially balanced flex plate for that combo? Was the Boss flywheel not weighted different for the balance. Since there were not automatic Boss cars I would ask some questions of those who know the Boss 302. You could do one mean burn out, lol. Nobody could touch you at top end speed.

You will need to run at least a 3.50 gear for that no torque Boss 302 to perform.
The 650 carb is a good choices for a street Boss 302 over the original 780. I think you will surprised what that Boss motor is worth.
