hmmmmmmmmmmmmmm
I have the short-block components which include flat-top pistons with 4.5cc valve reliefs zero decked. Want to achieve the best bang for the buck. Hope to get around 9.5+ CR so i am guessing a 110cc head. i have a HR cam with the following specs 234/242 .610/.632 112 lc. If i can use it, fine, if not thats okay too. Give me your recommendations on heads, intake, cam, carb, timing specs. Budget is $2000 for heads, $250 intake, $250 cam, $550 carb. With your recommendations give me your est HP/torque. Make sure to tell me rectangular or oval port in your set-up recommendation. Thanks, Dave
BTW, how much are used American Offshore NXS going for without power?
hmmmmmmmmmmmmmm
What kind of drive are you using (v-drive, jet, I/O)? That may play into what direction to go.

Keep the Crane cam, Canfield 310 (113cnc chamber then cut .050) / Air Gap w/2" open /850 mighty demon. If the comp ratio gets closer to 10 to 1 you wil be looking at 605-615hp @5600rpm 615-630ft/lbs. @ 4200rpm. Headers I hope. Done this combo 5 times with 489/509/ect. AFRs and canfields and very similar cams and manifolds. One 489 with Canfields and 242@.050 cam 599hp with Lightnings instaled. Your larger bore will do better (4.28 vs. 4.50)
The drive being used will be a I/O stern.
Hey machinehead what do you mean by "use 113cc chamber and then cut .050". I'm not well versed in the machine aspect of the heads. Thanks
Canfield offers a couple different chamber volumes. I know the 113 cnc flows well. And with the additional material removed from the surface by your local machine shop should yeild close to 10 to 1 comp ratio
