carb size for 512 stroker?

James,
With your miss match of parts and low compression and a bad cam.
There is only one way I would go to make a bad *** wild car.
Keep the 3.55's
Call the Super Charger Store and order there super charger.
Then order a F.A.S.T. 2.0 fuel injection system.
Get a super charger cam.
Now go have fun.

Are there any roller cams that in production out there that arent "bad"
