i just purchased brand new risers and exhaust manifolds. I strongly considered dry joint- but knowing the full fresh water cooling system is definitely in the mix, i just couldn't justify it. (the risers are on a total different circuit than the manifolds, and wet joint risers are cheap compared to dry joints every five years or so. )
having a short block in front of me, it will never be easier to recam. knowing the limitations of the heads and measuring out the length of the pushers in reference to the ratio of the rockers, i have room for a sausage cam a friend of a friend has possession of and i can get on the cheap- brand new, never ground. Sausage cams are popular in towing rigs- building torque down low and when coupled with a low-stall torque converter, provide a much better towing experience. figuring that same torque would be nice on the water, and because i'm not interested in RPM's/power curves above 4500, it seems like a great fit. I would hesitate to use it on a raw water cooled engine because of the overlap and inversion, but...... on a closed system? why not? is there something i'm missing?
