OKaaay (I guess), I may have found my kicker problem.
Just popped the head and barrels off this motor. Bore is for sure standard, which is great. Cylinders are do-able as is, which is also super.
Pistons- look good except for one minor thing. The compression ratio of these has got to be out of this world- I had no idea what road rocket or any other a10 piston should look like until I met you guys, I no longer think these are stock at all.
But before I go off thinking too much, does anyone have a pic of stock G/F pistons? None of that high test stuff, just cooking pistons.
These have the normal relief for the valves, problem comes with the dome- and I mean full dome- no flat area in the middle at all. When my buddy raced, these are what we would have called "head fillers", or "valve benders". Also, underneith the oil control rings, are 8 splash oiling holes- really reminds me of the alcohol cars.
If these are stock or sound like it, someone tell me before I chuck these up in the lathe and make flats out of them!
