Looks like someone is having fun! Nice Ford Coyote Pistons.

I'd like a better look at that porting on those heads. Any chance of that?

Looking good!

That purty!

So the 4 eyelashes in the Pistons were for a Ford? I would not think they would be needed for any Stude. V8.

Rich,
You can't get the Coyote pistons without the valve pockets, since the Ford is an interference engine.
(Something the Stude guys will have to put up with, unless we go with custom pistons....read that $$$$).

That looks like a really nice job, good work. How much oversize is this beast going to be?

The stroke is the same and the bore is now at 3.630" to give an even 300 cubes displacement. But with the head porting, better cam, and SN-60 Paxton at 5 lbs of boost it should make over 300 hp.

DSS Racing offers the Coyote piston without valve reliefs in a dome, flat or dish. Same forging everybody else uses, same CNC equipment, $150 less, plus I can stop in and check on them personally. But if you like the "D" or "R" name on the box you have to pay more.

Here's some pics of the work that was done on my avanti. My original factory engine received a competition build by Michael Myer while undergoing its frame-off resto mod. Originally an R1, Michael rebuilt the engine to something between an R2 and an R3 engine. The block was bored 0.060 over and received KB hypereutectic pistons. The R1 heads where converted to R3 heads with the combustion chamber enlarged and R3 valves. The heads were also ported and matched to aluminum R3 intake and R3 headers. The heads after being ported flowed 25% for air on a bench top test. The cam is 276 degs. duration. Edelbrock 1406 carb, Mopar HEI ignition and a SN-60 supercharger rebuilt with high output impeller boosting 8~10 psi. Michael estimates the engine to be 340~350 HP.
