first off this will be my first build, second im on a budget. how do i get a reliable 700hp out of this motor. lets hear some ideas
Sure, you could do it, Bob could do it, hell, I might even pull it off...BUT, we also have a selection of performance parts to put back into service... For years we raced Pro Stock with used parts. I've built more than one engine from the Recycler...... Here we have a guy wanting to kinda start from scratch, he has the stock stuff, but apparently, not a lot more..... When I did it, we were building "weekend bullets", one race weekend and tear it down to see what was ready to break... If you build a low budget deal, you're fully aware of the risks involved, and if one of those used, "serviceable" performance parts fail, it isn't the end of the world, you'll just pick up the pieces and throw something else together.... Now this guy, asking for advise, and "hints/secrets", is looking for something a little more "lasting"..... His performance goal is quite "lofty", and his budget, isn't....I just built a 477 on a budget and it made over 700. It's 12:1, 4 in stroke, Canfield heads, Straub roller, tunnel ram. Mostly used parts. It can be done
I'm assuming, (I know, dangerous to assume anything), that the motor in the boat now, runs... If it does, don't touch it!!!! Enjoy the boat as is..... Pick up another block, put it under the bench, wait for a smokin' deal on some heads, put them one a shelf... Slowly, as your budget allows, accumulate the parts for the "brute" motor, but don't mess with the running one you have... Build the brute, take this one out, leave it COMPLETE, right down to every nut/bolt...and store it... If, and or when, the brute fails, put this one back in and continue to enjoy your boat... So many people take a good running engine apart and wind up storing their boat for a few seasons, which is never fun....

Two biggest things would be the camshaft and the valves. You can run the stuff they use for valves, but I don't care to. Seen way too many "stainless steel" valves fail in a boat. Maybe in a drag only deal. But if your going to drive it like its installed in a 27 ft cat, you better BUILD IT. Not a simple "assembly" of parts.i for no reason see why you couldnt buy a Crate(RACE)motor from anyone one of the top manufactures and be happy:thumb:
How do you feel about a 25-30,000 engine in a 35 year old V drive?The motor heads didn't ask what the boat is worth
$14k motor into a 35 year old jet boat???
