Now that i have traded my 3000 stall converter for a 4200 stall converter. Wondering if it would be worth it to step up......or am i wasting my time and money???
So here is the spec's
408 stroker,
12.8 compression
Hyd Roller .563/.555 lift 243/247 @.050
RHS Iron Heads that flow 270 cfm
4200 stall converter
Shift at 5800-6000 RPM
LD 340 manifold with divider ground out and flange ground out for a TQ that i use to run on
this manifold
ProForm 850 double pumper.
OH! and one more Factor. Most of my racing it at 6600 foot elevation.
Keep LD 340 Dual Plain manifold or, run a single plain manifold...?...?.........
EDIT more info requested.
curb weight is 3860 with me in it. "heavy race car"
727 transmission
4:56 rear gear with a 28-10.5-15 M/T slicks
