I don't really trust the FMX I have now behind my motor, and really need a looser converter badly, so I'm considering buying a C4 and building it up. The Desktop Dyno puts my C at 509 ft-lbs of torque at 3000 RPM and 476 HP at 5500 RPM, on the bottle. The FMX already slips a bit when it gets hot at takeoff, and I don't wanna end up stranded.
Firstly, what era C4 should I be looking for... I see different spline counts on different units, which years should I aim to hunt for.
Do the FMX and C4 share the same flywheel, yoke, crossmember, and driveshaft, or are they different? It will be ratchet shifted (Hurst Pro-Matic) so shifter linkages don't matter.
What needs to be done to a stock C4 to beef it up adequately to hold me? I want to run a 10" converter in it so my stalls in the low 3000 range, and would like to get a shift kit that makes it sorta a semi-automatic valve body like I have now (when you put in drive it does all 3 gears, but if you shift into lower gears it works like a manual shift body). I would honestly ('cause I'm broke) like to find a busted, tired C4 and build it myself (easy trannys, RIGHT?), any good books to check out?
And if you have a busted, tired C4 takin' up space, let me know... The only one I've found local was a 6 banger tranny, and, although free, don't think its proly up to the challange.
