502 ramjet in 272
 

Anybody tried a 502 ramjet engine in 272 or any boat

Buddy of mine is running a pair in a 311 Formula. Make sure it is completely marinized prior to using.

marinized
 

What do you do to do that. I had my engine in the boat for two years.

You have to paint them BLUE of course!!!
 

Attachment 357740

A lot more than just paint was done to these, including:
*Different cams
*Re-worked the heads
*Marine head gaskets
*Upgraded rockers and pushrods
*Added crossovers
*All tolerances were basically built to HP500 specs.

And more including bigger oil-coolers.

We also added oil temp and fuel pressure guages to the boat as well. There was more I'm sure, but thats all I can think of off the top of my head at this time.

Engine paint job
 

Paint job looks good on that engine, I preferred anodize purple, I took the upper have of plenum, because I didn't want to take the intake off also, and had that anodized and then got two piece purple valve covers, and then I have the CMI headers. I will look up some pics. The engine runs OK, ecu needs some tweaking, top speed with a 23 pitch mirage prop, at 4900(wot) was 67 on GPS. I need allot of work in the engine compartment, replumbing, but you only have so much time to boat, and I do some work on it in the off season, but it gets to cold.
