4.255 will be the OD bore for 450 sleeves.

If you want a litle more power, the E85 will gain you some, but forget fuel economy.

I dont think they were really jetted right anyways from the start so rejeting the carb will help in anyengine that isnt getting fuel correctly.

Now, if you mix E85 with pump gas, say 50/50, you still get the power increase as straight E85,,, you will use less and make the same power VS straight E85.

E85 loves compression, more is good, but I would keep the cyl pressure under 220psi at cranking speed so it wont be as hard on the parts as if it had 250 or more for a worker.

Going from the M to the 450 piston setup, you will see a nice gain in power! Best to order the kit for a Super MTA,,,

so the rod bushings and wrist pin diameter will stay the same as the M at 1.3,,,

BUT,

the 450 uses a .990 pin, which will lighten things up a little bit.

Just get the adapter bushings for a 400 to get the right bushing for the small pin piston.

LOOK FOR FIRECRATER PISTONS!!

You find those, or M&W AP77's and dont look back. Hope this helps. ChadS

E-85 is for tree huggers that don't understand fuel consumption and people that want more power per cube but don't care about fuel economy.
