Ok here is what i have:
350 sbc 5.7 95-00 Gen1 GM block #10243880 came out of a 25' cruiser with mercury "duo prop setup"
We believe it has the roller cam in it?
The heads are #10239906 "L31" Vortec with 64cc chamber, 170cc intake port, 1.94"/1.5" valves.
Looking for a little more HP gain from either upgrading the heads, intake and cam. I really love the rough idle sound and I believe it is MRFixxu2 on You tube having a Comp cam 270h in his 18'.
So gentleman start your engines and give me feed back on possible recommendations. I would love to turn it into a 383 stroker but not sure if I want to go through all the machining but its not off the table.
This will be going into my 1968 18' Donzi.
Thank you in advance!!
