Here's a link to the cam page 12-236-3 - Xtreme Marine Although I have seen some streaks across the bay that look to be way over what my boat does! If I want to go fast I need to get away to another lake, which I sometimes do. I run on a lake with a speed limit, so really high speed is not allowed. I don't hold it wide open for long periods, that feels too expensive. If there's a bit of flat water I will run up to speed briefly. And it will do that with a pretty small amount of throttle once it's up on plane. It feels like it's turning as slowly as it can while sliding along easily. That engine speed keeps me on plane and seems to be a sweet spot in my engine's powerband. Most days I just tool around at 1900 or 2300 rpm. But I don't want to do that til I get screw in rocker studs. I'll keep my eye on Craigslist for some rockers, they come around every so often. To me they are for folks with deeper pockets or more determination who want to run at way high rpms. There are better anti pump lifters, lighter retainers, and roller rockers available but they are a lot more money. I did a little research about running at higher rpm and regular lifters are supposed to be fine for the 5000 or 5200 rpms these cams turn. It has the cam, lifters, springs, retainers and keepers. It has what I need included as a package that's very complete. The kit I am looking at has Comp's 12-236-3 cam at it's center. I really do like engine noise, but if I don't have to keep my exhaust open to keep it dry I can go out early mornings without ruining my neighbors coffee or sleep time! To me that's valuable in avoiding reversion. My type engine has been around for a long time, I bet COMP has gone through the learning about what can be done. I have found other cams with good improvements, but what I like best about the Comp one is that it's from a big reputable company and it's specifically for sterndrive engines. Since I haven't done this before I am thinking it best to stick with them as one source so their parts can be expected to work together as a system. That kind of thing is OK with me, I'd rather not go too far and regret the choice. I asked their help line for an opinion and they dialed me back to this cam, I was thinking too aggressive, too wild. I am sure they want to sell their stuff, but I get that and I'm OK with it. I have gone onto Comp Cams forum and gotten some input. I've been doing some reading about improving these engines in hot rod and hot boat sources. Too bad, that's a chance I wish I could get back.

#Comp cam 350 sbc marine code#
I never did write down the cam code when I had it exposed. I did a timing chain to it last spring when I had the covers off to get rid of some oil leaks. 2 years ago I tested the compression and got 170 to 185.
#Comp cam 350 sbc marine serial#
The engine is a 1988 5.7 serial # with the 64cc combustion chambers. Hi, My boat is fairly light for it's power and I want to try to get all the oomph I can out of it.
