Looks like I have finally acquired enough pieces to drop it all off at the machine shop..
.....Thought I would run it by you guys and see what ya'll think...
This is going in a 24' I/O and has to run N/A for this summer but I plan on adding a Procharger next year as $$ permits..
I'm well aware some of the parts I'm using are not the best out there but hopefully good enough to stay together and make reasonable power..
Ok, with that all out of the way here's what I have....
Dart big M tall deck block billet mains 4.560 bore.
Eagle forged 4.25" stroke crank turned 10 10
Eagle 6.535 rods with ARP 2000 bolts
Cleveite H series bearings.
Manley forged 2618 pistons. -20cc dish. 1.520 CH
Sealed Power Plasma Moly file fit rings.
Pistons will be .005 in the hole..
Merlin "Grumpy Jenkins" Iron heads.. 320cc runners 119cc chambers
2.25 in. stainless intakes 1.88 inconel exhaust
Fel Pro .041" MLS head gaskets
It'll be a Cam Motion hyd roller cam & lifters
Something about 240in 248ex dur. .630" lift on a 114 lobe center
(waiting on the heads to decide)
.... Intake / Exhaust.....
Cutler EFI intake with 42# injectors (for now)
Fast throttle body Mefi 3 ecm
Early K/E (Drake) manifolds dry to the tips.
Hoping for 600hp at 6000 rpm N/A but don't know if the heads are gonna cut it...
Now a couple questions I have....
Will doing a bowl blend on the heads help much at all or is it just $$ wasted ?
Speed Pro suggests .006" per inch of bore for ring end gap supercharged which comes out to .028" is this enough for supercharged marine use ?
Manley suggests a piston to cylinder wall clearance of .006 for ALL BBC applications is this sufficient ?
Any advise / input is greatly appreciated...
