Forabodiesonly member heading to final round

Yes John you’re correct it’s an Indy 600-13x headed engine.

622 cubic inch. Naturally aspirated. Indy tunnel ram intake with 2 dominators (I believe 1250s). Dry sump oil system. Jesel belt drive and rockers (I believe 1.8 or 1.9 ratio). Carrillo steel rods, crower 8 counterweight crankshaft, diamond pistons. I forget the bore x stroke and compression but I wanna say at least 16:1 compression. The camshaft I do not know the exact specs I just know it’s big lol.

It was dynod when the engine was originally built many years ago but I can’t remember exact numbers. I know the fastest the car has been was in the 4.50s at 150mph but again can’t remember the EXACT ET and MPH. I just know it was in the 4.50s.
It’s a beast.
