I would contact him and ask who he recommends. He and several others have been through a TON OF GRIEF over there in Chicago with marine hi-perf engines. Before you make a decision I would call/talk to Frank. You will find him in the Chicago Powerboat Club section here on OSO.
Just a word to the wise....the last thing you want is finding out the guy/shop you chose to do your engines ended up being a disaster and a ton of grief! |
On that 540 build- that all sounds good. Couple of things I'd change;
Crane golds instead of the scorpions Crane Hi6M instead of the MSD AFR 315CNC's on heads The new bulletproof Morel hydraulic roller lifter Make sure the valves are manley or Ferrea, not Eaton You should be very pleased with that combination. Now, look into drive upgrades. (P.S.- $13K isn't a giveaway price. I'd shop some other guys on it. Gellner, Eddie Young, etc.) |
Rob,
My personal opinion is to stay away from Scat or Eagle cranks. Go for the extra $$ and get a Callies. I agree with Chris, no scorpion rockers and stick with AFR 315 CNC heads. |

What you do to the drives is dependent on you as much as it is on the boat and power. If you want to do full-throttle holeshots, if you want to do big wave jumping and you don't want to take the time and effort to learn and exercize proper throttle discipline, you'll shred the XR. Driven sensibly, the X upgrade will probably do you just fine. Merc outdrives like to be kept cool (drive shower) they like fresh oil and they like to operate inside their clearance specs. Essentially, you can keep one around with a little common sense on the sticks and regular fluid changes coupled with having them gone through periodically by someone that knows what they're doing.

This is my Achille's heel on projects. It's constantly "only $500 more" until I'm into Sterling money into engines that were supposed to be "just warmed up a little". |

I tried my damndest to figure out a way to make the same kind of power with a head other than the 315 CNC. There just isn't. They only look expensive. There's no better or cheaper way to make that kind of additional horsepower.
