Wondering if anyone has any first hand experience or knowledge of which cam application might better suit my build. Twin GEN VI 454 MAG/MPI's, keeping the fuel injection, not interested in going carburation.

The Teague BBC GEN V-VI Billet stage 1 : Advertised duration 288/296 .50degrees 226/234 LSA 112 587/610 Gross lift
Comp Cams BBC GEN VI HYD ROLL " " 283/290 .50degrees 223/230 LSA 114 566/575 Gross

Staying with the factory bore & stroke, factory forged internals all stock, doing a 3 angle valve job and matching springs for which ever cam I select, adding roller rockers. Re-plumbing the fuel system removing the VST and manual pump assembly adding full electric fuel systems with adjustable fuel pressure regulators and having the ecms reprogrammed for the new fuel and air flow upgrades

Any opinions?

if your thinking of the teague cam,,just get the crane 731 20yr old tech cam that works.

I'd go option 1 but that's just me however a proven cam time and time again.

Aren't they pretty much the same?

I've never confirmed timing events btwn teagues version and 731 however I would imagine they are very simlilar. One nice thing with Teague is they would likely assist with fuel/ecm etc.

the teague cam is a crane 168731 cam.

The answer will be given by whomever is doing your computer programming.
