first off, anyone know how a f303 cam would do with a turbo? i hear alot about it being a good blower cam, but what about turbo?

next is the carb selction. its a 351w with a f303, and bbk unequal length headers and a victor jr intake. im thinkin around a 650? or so? (the carb will be changed when boost applied)

looking for opinions. maybe from someone who has done this setup?
thanks guys

I have not used a F-cam with a turbo but there is a guy on another turbo board named Brent Davis who made 800 + hp it may have been even more but it was a **** load. so yes they work well with turbos. He is not the only one there a good many guys on that board who have used the F cam with great success with a turbo.

thanks man. im looking forward to boost. anyone know what a 351w will hold boost wise on stock internals. and i mean reliably not twice and then it blows haha.

I would not trust cast pistons to any boost. but that is me. other then the pistons the rest of the parts I would not be to worried about till the 500 hp mark then I would be changing out the rods for a better H beam or I beam there are plenty of guys that run the stock rods at high HP but I have seen to many W rods fail to trust them but they where in higher RPM NA motors also. the block and stock crank will hold lots of HP if done right.
As far as how much psi. they will hold. boost is just a measurement of restriction so low boost numbers on good flowing parts could be very high HP numbers compared to high boost numbers on parts that dont move air as good. so I dont put a bunch of faith in boost numbers. Turbos tend to be softer on parts so with a good tune the thinking is that you can make more HP on a given part then you could with N/A engine or a S/C engine with the same parts. I dont know if it is true or not.
