How you think she is going to run? Any ideas on power out put. I would like to ditch the c-6 and get an adapter plate, bolt up a late model 6 speed, that is the next project($$$). Im thinking my cam is a little small for the amount of flow i have. Im going to give her a try, if she need more cam then i'll swap emm out in the truck. But sence its an F-250 that will potentially haul a lot of weight over big mountains I wanted an easy cam. <br />

looks pretty good. If you have a little left in the budget, look at the Crane 349521 Hydraulic roller. It will let your engine breath a little better at the upper RPMS, but not take the bottom end completely out. I run it in my F250, that I intend to use as a truck but also play with at the track. However, the Hyd. roller lifters, custom pushrods and matching springs etc will add a good bit to the price.

422"

I came up with 518 tq @ 2,500, 414 hp @ 5,000, VE% 92.8 @ 4,000, BMEP 184.5 @ 2,500. This was with .500 lift, IVO 31*, IVC 63*, EVO 77*, EVC 29*, 274/286* cam. 106/114 LS, 60* OL. Nice animal for the street.

It sounds like a good torque motor. I think you could easily run more cam without hurting the bottom end much, while gaining some higher up. I also think the 670 cfm will not be enough for any extended spirited driving. I had to go to a 750 in order to feed my 433, the 650 double pumper would not flow sufficient air.

BTW... how did you keep your work area so blasted clean!!?
