Probably around 475 FWHP @ 5600 RPM's and 500 FWTQ @ 3800 RPM's. That looks like a great cam for a streetable 408w. Nice combo. I hope you have some traction upgrades because that will be a torque monster.

3500 stall torque converter for "Street Manners"... What friggin' street do you live on?

Sounds like a great ride! I think 475 rwhp, might be just a bit optimistic though..

505 Hp, 525lb/ft....that's my guess.

I was thinking the same, add in the lack of vacuum advance and mech secondaries too. I tuned mine way down to make it streetable and have functional power brakes.

Yup, I was thinking 525fwhp, you'd be pretty lucky to put down 475 with that (assuming our guesses are right).

thanks guys, my converter will stall from 2800 to where ever my power curve is, special JPT 10'' converter, jim says when you mash the pedal look out, my engine guy seems to think 475hp, but who cares i need torque down low from light to light, not worried about 6000 rpms unless i race it once in a while, street car and little race, 500ft lbs is a lot of torque man this thing going to brake something i have a feeling, cant wait to fire it up soon. thanks, what gears should i run on this thing, 3.50 posi now.
