Sep 20, 2012 · Cast Eagle 3.85 crank here with Scat I-beam rods and DSS pistons. In a 1971 block. It's worked fine with no issues so far in a street/strip Foxbody. C-4 with a PTC 8" custom verter and 3.55 gears. NA shift at 5800 with 10.60's. With a 100 shot shift at 5800 and go in the high 9's. Pretty reliable and no issues.

May 21, 2012 · Second with that kind of lift and Springs ditch the 3/8 push-rods and go to a 7/16 double taper with 0.165" wall. Your valvetrain will be much happier with that.

May 8, 2008 · Even though Musi does the machining of the Dart Big M in house, the Musi engine builders check every single block before assembly.

Feb 14, 2010 · We all know a 4340 or 5140 cranks are much better then 1053 even us old school phuckers and 1053 steel there not junk. With no cranks in the closet 4340 new would be my opinion also.

Sep 12, 2009 · 671 on a SBC w/ a mechanical water pump. I got the motor back from the shop (who should have known better) with a single key on the crank (eagle 4340 + prof products balancer).
