I usually just read on this forum, but thought I would share recent results from my 393C build.   Specs:

Scat 3.85" crank

bored .30" over

SRP Pistons

Isky roller cam:  218/228,  LSA 112

Isky hydraulic roller lifters

Trickflow 195 heads 72cc chambers,  1.55" springs

Edlebrock Air Gap Intake

Sanderson FC4 shorty headers

Holley Street Avenger Ultra 770 - elec choke, vacuum secondaries

DUI distributor

10.6:1 compression

Peak torque was 499 ft lbs @ 4200 rpm.  Peak HP was 501 hp @ 6300 rpm.   10 deg advance with vacuum.  Not bad from a relatively mild cam.  

The engine will go back into a 71 Mach 1,  with an FMX auto.

Quick Performance Posi 3.5:1 gears,  31 spline axles

I chose the parts based on what I learned here,  and from posts/publications from George Pence, George Reid, 7173 Forum and others.

Assembly  and dyno was performed by Westside Performance in Houston.   I'll try to post more pics and a video if I can trim it to the upload limit.

Very nice! I am somewhat surprised at the 6300 HP peak with that short duration cam. Should be a lot of fun. Well done.
