OK...we have a plan for the new build and here's what we got.
JNW Engine here in Santa Rosa will be doing all the machine work. Thanks Terry for recommending me to him.
The block needs an align hone bad. It should've been done on the original build since I switched over from main cap bolts to studs, but my previous machinist never told me that I'd need to do that so I didn't know it needed to be done. But we found very uneven wear on the main bearings which points to the fact that the block definitely needs it. So that issue will also be addressed.
0.060" over 454 (468)
Eagle Forged 4340 crank
Eagle H-beam rods
SRP Small Dome Pistons
Comp Cams Xtreme Marine XM278H cam
Comp Cams Pro Magnum lifters
Edelbrock Performer RPM aluminum heads
2.19" intake, 1.88" exhaust valves
Scorpion 1.7 roller rockers
Comp Cams Pro Magnum 3/8" chromoly pushrods
Melling 10778C high volume anti-cavitation oil pump
Some parts from the previous motor will be used:
Edelbrock Performer RPM Air Gap intake
Comp Cams double roller timing chain (if it degrees in right...may have to get a different timing set due to the align hone)
ARP main cap studs
Holley 750dp marine carburetor
Canton marine 9qt oil pan
Scat FP454SFI flex plate
Powerforce 8" harmonic balancer
MSD 6M-2 ignition w/R2R distributor
MSD Soft Touch rev limiter
Hopefully I can get her running and back on the water by the beginning of May. We're estimating around 500-550hp.
The pump is also going to require a rebuild since the impeller was coming apart and the shaft is out of round beyond spec. The wear ring is good though and we'll be converting from the mechanical shaft seal to the traditional rope seals in an attempt to correct a holeshot issue I've had since day one. But I'll be running an A impeller this time (previous cut was an AB). Hopefully this thing will jump right outta da wata with neck snapping acceleration.
