cam only dyno # inside just got back from the dyno.
386.6hp @5600? I think the rpm wasnt calibrated right.
420.8tq? @3782?
hp + tq met at 4800rpm
on a mustang dyno running dynojet software, through slp2otl
max power was at 129mph... max tq @ 90mph
with mustang software and cutout open.
345.7 @6000
342.7 @4171
hp + tq met at 4000rpm
mods in sig.

Calling a 355 cam only is a bit misleading. A properly done shortblock is worth some power.
HP and torque can not meet at 4800 rpm so there was a problem with the setup or software. torque multiplied by RPM divided by 5250 equals hp so the 4800 is a problem with the setup.

ya its a little ole 355. heads are unported 
intake unported, stock throttle body
where should the hp and tq meet? I know the rpm cal was off cause I know the max hp should be around 6100-6200
corrected # are 375hp and 408tq
and I did beat a cam only ls1 that dyno'd 389hp. by about 1-2 cars so I know this is a big torque motor.

unknown specs on cam, just know that its a custom lme shaft. sotp car quits pulling right at 6200 I spin it to about 6500
both pulls had a hickup at about 4900 hp fell off about 2-3hp for about 25-30rpm then picked back up. torque fell off a little more.
