what kinda of power do you think a 347 with ported 351 heads with bigger valves and a 550 lift cam and a trickflow intake and 24 lb injectors (heads are 60 cc)

 

to many variables, take it to the dyno and find out . Probably around 350 at the crank, just my guestiment (dont know what stile of intake, compression, internals, dont kow enough about the heads,)

 

Not enough information to know.

Lift is only "part" of the equation with the camshaft, and a very small part at that.

How many belt driven accessories?

How ported the heads? Volume? Quality?

Which TFS intake?

Pay $50 for a near by dyno and have them do 2-3 runs.

Then you will know
