Re: Scat vs Merc crank
Put a SCAT stroker (4.125) rotating assembly in my 59A/B. Out of the box, you could turn the crank with two fingers, with the mains torqued down. Still holding 35 psi oil pressure at idle, hot. No problems in 3000 miles of daily driving, - and I do get on it pretty hard from time to time.
So far, I think I got my $1,800 worth. |

Re: Scat vs Merc crank
I used a crank assy from JWL as well. I didn't know the type it was but it went into a Hydro engine and it also ran very well for many years/ I think it was a 4 1.8 crank??

My son balances almost all my shafts now on our CWT/Turner and has never spent more than 30 minutes for the FH Eagles, this time doesn't include making up the bobweights, only to "read" both ends and do the actual corrections. Eagle's cast-iron material drills like "butter", but this is true with the Scats also, both brands drill really easy. I've NEVER had to "fill" an Eagle nor have I had to remove any weight from opposite sides of the counterweights! There's absolutely no reason these shafts should ever need filling (assuming a 1500/1600 grm bobweight) if they are cast up correctly and pre-machined by the vendor? I'll be totally honest here and say the only single item to watch with the Eagle's is the clearance between the front side of the #2 main and the radius on the crank. Most clear OK, if they're too close it's a simple "at-home" fix with a small die-grinder, nothing "precision" needed. Thanks, Gary in N.Y. P.S. With respect to the entire Scat (crankshaft line), we rarely use their brand, only time really is if they "come in the front door" (customer-supplied). It all boils down to too many balancing issues with their stuff, and it's NOT only the FH's, it's the popular SB and BB Chevy's as well! On the "flip-side" their FH rods are excellent for these units, on these we won't use the Eagles here.
