What we have here
505 stroker
Stealth Heads very mild porting (just tidy up)
10.5 comp with assembled quech at .040
Hyd roller cam with 230/230 @ .050. lift .576/.568 on 112 lobe installed with no advance
Factory six pack induction
Factory Hipo exhaust manifolds with twin 2 1/2 exhaust with X pipe
On the engine dyno this made max TQ 575 @ 3350. Max HP 494 @ 5300 (this was with a twin 2 1/2 exhaust and mufflers hooked up)

The car:
70 Cuda
auto with 2200 converter
3.23 posi with 28in tall tires
Power brakes,power steering.

I know obviously a set of headers and maybe a 3in system would do wonders for this combo but the ex manifolds need to stay. The dyno operator has told the owner he is leaving some on the table with this cam chioce.

Anyone care to provide some input on this?
Thanks Tim
