I thought about this and it would get me on the water lots faster. It's still a lot more power than the 305 that was in the boat. I've read the GLM's are copycats of the Kodiaks and I will make that improvement atleast for this year.

I looked at one more cam today. This would be running 1.6 rockers and with the GLM manifolds out the prop. Any opinion's on this Crower grind?

I run the 483LM EFI grind from Crower. It is a step up or two from the one you list but I don't run through the drive. I can't honestly give you an answer how it would behave exhausting out the prop but I am happy with the cam choice and product.

38 Special, you are not doing things 100% the way you wanted when you started this build, therefore you are getting yourself caught in erroneous thoughts.

Stop over thinking.

I would say a 212,218 at .050" on a 112LSA will be fine.

If you want to push it a little, a single pattern 218,218 at .050" with a 112LSA might just do it.

Going to A 114lsa cam in a small block makes it lazy. 112LSA is bad enough, but what we are forced to in the marine world. Outside of boats, we would be 108 or under...mostly under. Just sayin.

Go get a cam and finish the build. Liquid water is coming soon.

I agree with SB. A 212/218 even with a 110 would probably be fine. Ran a comp 260H 212/212 110 with stock exh on the org 5.7, no problems. I'd go the 212/218 hyd roller comp and be done with it.

I am so far removed from where or what I started out with. Lol Now I'm sick of looking at cams I can't hardly take anymore. I had made up my mind on this one today until I had seen you guy's new post. Tell me more about the single pattern 218,218 @.050 with 112LSA. Can it be had in hyd roller and what kind of lift? Is it a bit more aggressive?

Excellent choice for stock to mildly modified engines, works well with OEM style injection, great inboard/outboard marine cam for economy and sking. Good mileage and torque increase.

Correct me if I am wrong but it looks close to your first recommendation above.

I am listening. How would you compare the 212/218 you mention to the last cam above I post specs on? I read today comps share much of the same design of the lanuti voodoo series.

This was the idea for the start of my build and then I ran across the Kellogg stroker crank. Of course I didn't know or even think about headers or a good exhaust when I got it in a boat. 444 ft lb and 470 H.P. from a 350 with the EQ heads and the 108 LSA cam.

Heres my dyno numbers...

Those are the numbers I expected to see when I got done with mine but that was back in the take home a couple of grand a week days. Lol Now it's take home $1,700 every 80 straight + 30 hours more time and a half and the overtime has leaned out a lot so needless to say it has changed the complexion of my build. It's all good, at least I'm working and I am still going to enjoy a 383 in a light boat which is a step up from the 140 mercruiser tri hull that was my first boat.
