its a 1997 350 cui SBC and its getting
Vortec heads
performer rpm intake
the pistons are 9.8:1 forged flat tops
the block was decked
and here is a link to the cam kit im using:
http://sdparts.com/details/gm-perfor...parts/12480002

ive been told it should be around 380-400hp

im still undecidied about a carb tho,im thinkg i should stick with a 650 but a 750 still lurks in the back of my mind altho it may be to much

I would say the 750 cfm would be to big but im no expert

I'm no expert either but I would check those cam specs up against some other marine cams and see if the duration and overlap are good for a marine application. Mabe contact one of the cam guys here on OSO. I might also consider using the Edelbrock carb to go with that intake. Just some thoughts. I know marine cams are different designed than cars.

Ive talked to a few people that have used this cam in boats with great results. i have also looked at a few marine cams with close numbers to the one im using so im crossing fingers and hoping they are right.
