360 in 64 Val?

I did the same to my Barracuda a few years ago, and then last year I installed a T-5 and pulled the 4-speed. I have the 273 flywheel that I had balanced for the 360, had it on another site for $100 plus shipping.
I have the motor out of the car right now, and am waiting to reinstall it until I get a set of headers.
Let me know if you're interested in the flywheel, I can send a pic to e email address or cell.
Oops, I should've read the rest of the post, I see you have the bigger bellhousing already,,never mind on the flywheel.




The bigger issue is not power loss but the flywheel. You have the smaller early A clutch, right? If the engine internally balanced? Is the crank drilled for a 4sp? The early A uses a smaller diameter clutch and flywheel with a different crank hub register, and it's not balanced for the factory type externally balanced 360. If the engine is internally balanced (would have had to be done when it was rebuilt) then you only need the bushing for the crank hub. If you can overcome that stuff - you'll lose a bit but overall it should still make more than what you have depending.
