If some one could dyno this for me it would be greatly appreciated. If I forgot something please let me know. Pistons should end about .005 in the hole. I think my compression will be about 12:1. I would like to make about 500hp Thanks in Advance, Brock

Should be in the 500hp area.

Your compression will be in th mid to upper 11:1 range

Ditch the Stealth and Get a victor Intake and 1050. That may get you to 550 or maybe a little more.

how high do you plan to rev engine? i agree i would use a victor intake but heads will need to be matched to intake ports. if its a street car your modified 850 will work best your enine at 6800 prm in race trim requires 1007 cfm.

Engine usage

This engine will be going into an early bronco. I will be using it for mud and dirt drags. The engine will probably be spinning 3500- 6000 rpm normally.

You have a shoe horn? :)
The only early bronco's I've seen with the 385 series, was cut up, witch would put you to pro stock or up around hear. Would love to see some pictures.
Good luck.

Definetly ditch the stealth and 850.
