Saw these in the Summit store online

OOPS! I completely forgot about WHY they don't work that way!

the flat tappet cam lobes are ground at an angle so they rotate the lifters.... Yeah ur right of course can't use rollers or they'd be riding on just the edge of the wheel.... sorry for any confusion.

Hey Aussie, has any one laid that 3.7 cam beside a 460 cam? Wonder if you could run a 460 cam on only use half the lobes? You'd have to bore the end of the cam to accept the shaft for the water pump though.

i look at that the distrubtor gear would be a problem so i think that's out

I guess a lot of you guys are thinking why am i wasting my time and money on a small 3.7 when i can drop a V8 in my V and have all the power i want here are a few reasons why i haven't gone that way

( 1 ) prices for a S/H V8 boat engine are too expensive here

( 2 ) don't wont the extra weight

Reasons why i stuck with the 3.7

( 1 ) the light weight of the engine and even more with the alloy head

( 2 ) engine parts being cheap because same as a 460

( 3 ) fuel efficient

( 4 ) Most of all being a unique engine having a smaller engine making
good power is more rewarding than dropping a V8 in it when i do go
out for a fish and my boat is more fuel efficient than my mates boats
its a fishing boat and will be well balanced with the 3.7

Not me... I like the 4 cyl plan

Aussie, you're doing what i always wanted to do with my old room mates Stingray 176(had the 3.7L 165 hp), more power to you for doing it, but just don't over complicate it

What he said. Nothing against the 3.7L, and I think MERCRUISER screwed up by ditching it for the 4.3L V6. But I agree that your over complicating it many ways. Build the bottem end up, put a good head on it, call a good cam company and have them see if they can do a regrind to peak the engine for your application, and call it a day. Electric water pumps and other extravagant things on a boat are just head aches waiting to happen. Build the engine up, but keep it simple.

I forgot another reason im keeping the 3.7 a few members told me that they make good power for what they are and I only took the boat for one short run and had the push rod problem so I couldn't tell how good it was
