I think your right on the cam info. I would use a 248I/254E duration @ .050 on a 114 LSA. Those profiles will support .660 - .680 lift with good spring durability.

Bob Medara !!!!!!! is your best bet to get the cam u need !!!

These are bolting to Arneson drives ASD-8.
My goal is 700HP to 750HP so I hope the cam selection works out. Do you feel I will not get there with these heads?

Ken those heads will work PERFECT for your application , and if you need more Hp at a later day put a blower on ...:drink: you'll need to add some duration to the cam shaft

I think you could use more than 248/254, the GM ZZ 572 runs 254/ 264 and makes peak HP at 5500. This is just an opinion, I'm not an engine builder.

Ken I have a cam that I just pulled out of my 598. It is a solid roller it is .730 lift Int. 262 and ext. is 269 112 ls and it made 827 hp at 6300rpm on the dyno if you want it give me $150.00It is a RM Builder cam

I have a Solid roller cam and lifter setup as well for sale. PM me if you are interested and I will give you some specs. Made 800hp in a 598ci N/A at 6300rpm.

Ken give Bob a call i think you'll like what ya hear, no need for a SOLID and the Xtra work that goes along with it ..He just dynoed a 1430 Hp motor with a Hydraulic .good luck

I have a project- a compound project:

The Block is a Donovan 11.1 Aluminum block.

Crower crank with Olds style mains and center thrust, BBC rods, BBC oil seal.

Oliver 7.5 rods with pin oilers, good bolts.

8.8:1 static compression.

AFR CNC 357 heads.

Custom manifold.

Automatic Reseting (linear motion with Teflon for all fuels) Blow off/backfire valves.

Intake manifold EGT.

Exhaust EGT’s.

Two bank Wide Band 02’s

Isky red zone bushing lifters.

Custom Solid roller with appr. .750 lift intake and Exhaust with 290/300 on duration. 114deg CL installed +2deg.

14:71 Magnesium blower- my plan is to make 6lbs with that unit and run the turbos on top of the blower.

Currently Crane Hi-6 and crank trigger.

Hey RunninHot, what intercoolers are you using? Who's making the manifold? Sounds like a cool build (both you and Ken).
