Gen V 502 rebuild and tweaking.
Ok guys I've been seeing low oil pressure on my gev V 502, it started life as an OMC spitfire ignition engine but now sports a standard style distributor etc. I'm going to have it pulled and rebuilt, but while it's out maybe warming it up a bit. The motor already has stainless marine manifolds on it and was thinking about simply taking .020 of the heads and putting a mild cam in it to get to about 500 HP -- nothing crazy. Also maybe changing it over to a roller motor, are there bolt in kits for this?
Any suggestions/specs/etc. would be helpfull!
Let's hear your ideas, GO!

I know you like to do work on your engines but machining work is too
important to leave to just any local shop. You have two good options
within a one day drive.
Your closest option is: http://www.crockettmarineengines.com/products.html
Tyler's kits make good power.
Your best option is: http://www.youngperformancemarine.com/
Eddie is the best one stop shop.

This guys does rebuild for a bunch of marina's around Detroit -- he's on Livernois and something, I can't remeber the cross street. He does all the maching except the block.
Tyler Crocket is out man, I called him three times over the last month and also e-mailed and never got a response. I don't care how good you are, with that kind of service I'll never give him a dime.
The starting point here is $2800 depending on what he finds it will only go up. The machine work and a new cam will be minimal additional cost, and depending if I convert to a roller cam. He magnaflux's the heads and block as well.
I'm certainly open to options here -- I'll give youngs performance a ring, they are inprogress of pulling the motor now.

I just figured 90 miles vs. 500+ miles it would be a good option. Too
bad for Tyler I guess!
I won't have a shop R & R the engine, a 2nd one do machine work, a
3rd or 4th spec/order parts then someone else dyno tune and then
"in water" test and "final" tune an engine.That is just not worth it to
me. I had enough headaches just doing a simple engine swap.
Eddie's shop is the best option for me. He will also address your fuel
supply and oil cooling needs should you go over 500 ponies. Those are
some of the little things that will bite you in the a$$ when you try to do
things yourself when you might not know what to even look out for.
Best of luck whatever you decide.

Maybe something simpler, since I'm planning on moving to a roller cam -- how about the specs of an existing engine, say a mercruiser HP500, anyone know where I can get the specifics?
Gotta believe somebody knows this stuff here, maybe I'm talking crazy, so somebody set me straight.
