A while back I made a thread about helping my friend on his 383. We are using machine tech in oceanside...

They have all the machine work done and all the parts except the 9:1 pistons they were going to use from keith black have been on back order for over a month.

The car is sitting in a borrowed lift stall so we need to get it out of there.

They have the block measured and the factory closed-chambered heads CCed. They said there is a similar price piston in stock (not sure of manufacturer...I can ask) that they know they can get that will put the motor at 10:1.

I went with the reccomendation of one of the guys at IMM and got the comp 265DEH. Car has highway gears and a 2200 stall...will 10:1 work on california 91 octane?
