Its time to replace the cam in my cruiser engine and I'm looking for some suggestions on what to do next. Here's the engine specs
454 + .030 4-bolt
840 closed chamber rect port heads
11.2:1 compression. I have to look up the piston numbers again, but I remember it being about that. The pistons are TRW forged L???? I'll have the heads off soon and get that number.
Hydraulic cam (unsure of exact number, haven't had it out of block yet. Purchased motor complete in boat)
Double roller chain
Intake system is the complete Holley HP EFI kit seen here. http://www.summitracing.com/parts/HLY-550-831/ I also purchased the computer controlled marine distributor and most of the sensors, including two knock sensors for each side of the block. This set-up is currently up and running for its second season.
Connected to a velvet drive tranny and champion v-drive.
Here's the use. I use it for cruising around with the family and doing a lot of wakeboarding, skiing and pulling tubes around. I would like something good at the bottom end but i cant still get on it when I want to. The current cam has a little lope to it at idle but smoothes out well off idle. I'm more inclined to stay with the lower RPM cams for my use but would like the upper RPM ranges 5500-6500k a reasonable possibility. I'm looking at hydraulic roller profiles and reading some articles on them that make them a little attractive, except for price. Another hydraulic obvious could work as well. I know enough (not everything) about motors and have built all my own engines for racing and pleasure. Any experience or suggestions with this would be helpful.
