Rebuilt 904 non lock up, with 2300 to 2500 stall 3.55 gears. Thinking it will make for a peppy engine, that doesn't kill fuel economy. So Im thinking 300 to 325 hp and maybe 400ftlb. So Think this is a fair estimate. It be even better if It would break into the 14s!

Photobucket sucks

The plan is to put a hyd roller, and roller valve train, with next years tax refund. Just didn't have $$. I still think this cam will do ok, and will be easy on the pretty much stock magnum valve train. Thanks guys

I built a 360 many years ago that used the same Crane cam,j heads(home ported),RPM intake,headers,904 lockup trans,stock slant six converter,gearing was3.23 ish. I installed it in an 87 Dodge 150 2wd long bed for a daily driver(4000lbs? with me). Got great mileage and drove very nice with enough grunt to smoke the tires from 40MPH rolls. It ran 14.20's smoking street tires @100-102mph without tuning . It ran better with smaller carbs than the 750 holley.It was done @5200rpm so it's not hp build but for a truck its not bad. I think you'll be ok with that combo. Put the same engine in my Duster ran low 12's @110mph shifting @ 5200rpm.

I have no idea what your springs are but I'd guess the valves are longer than stock or the guides are shortened to get that much room,with this cam you don't need anything trick at all. 110-130seat 275-300open is plenty. Stock rockers will not be an issue with those numbers. I'd expect with good tune and traction mid 13's would be a breeze.
