I wasnt really impressed but this is the first time I have had one of my motors dynoed. I have a bigger cam I need to put in. This is in a 87 ranger mud racer.
Jon, Is that a Lunati cam part number 5106? It sure looks like it by the specs you gave. I ran that cam in my 557 with reworked A429 CJ's. I never dynoed the motor but we estimated about 850 HP. It ran a best of [email protected] weighing 2600 lbs. I run alky also. I had a lifter failure so I am switching to a custom grind from Carroll Carter at C&C Motorsports. The old cam worked OK but we felt like it was a little on the small side for my motor. I would definitely think with your heads that you could use more cam.Just my 2 cents. Good luck

Arias Pistons They that are a shelf piston with the Dual Intake Valve reliefs cut. 7cc dome
The heads were done by Ford Performance Soulutions. Long story but do not have them do your heads!!!!
I flat milled the heads .100 only to get the chamber down to 80cc's.(Dissapointed) FPS ran a cnc program on part of the chamber and really opened them up to much.
compression ended up at 13.5-13.8 to 1.
Yes it is the 5106 Lunati cam that is in it now.
My new cam is 284 304 @.050 .830ish with 113 lobe sep. I have not installed it yet thou. I want to switch cams and re dyno and see what happens. The new cam should defenitly move the peak HP up. I think with this new cam it should peak around 7500 rpm and make 850 HP at least...I HOPE!!!! One thing I think is interesting is I think it would make a great street terror engine, if you could afford fuel. It really doesn't sound that radical,Sounds very healthy but not radical.
