What cam should i use 360 build

I can only make recommendations of what I consider a rat rod? Meaning a cool looking cruiser. You didn't mention how much of a "race" sound you'd like or how much "drivability" is involved? Not to mention weight, gearing, converter, etc?

My opinion is, you need enough carb to take up the large plenum with a single TR. I'd probably go with a 750DP type carb with well tuned pump nozzles and as much initial timing as the combo can handle for "drivability".

Cam choice can be all over the place. Lot's of the "off the shelf" grinds can give you sound/drivability.....it really depends on the specs of your combo & and what you want from this build?
