Piston Emergency

I have my 460 at a motor shop being worked on its getting a mild build, and the shop can only find stock cast replacement pistons of 8.0 to1 compression at $25 a piston or a hyperuetic for 8.7 to 1 at 125 dollars more per set. He told me that TRW has gone out of business, so i need to find a set of cast or forged pistons to raise my compression to around 9 to 1, for closer to $30 so i can afford this can any body help me out here i have to take the connecting rods done there tomorrow.

TRW didn't go out of business, they were bought by Sealed Power, who uses SpeedPro as their trade name.

i always thought that more compression would be better too, but i was ressntly told that for truck& tractor pulling that unless u have something like an NTPA truck it aint necessary if u wanna run pump gas while at a pull with todays gas it is possible to predetonate, which is why industrial gas truck run low compression, anyways at this point i dont have much money left so stock replacement pistons were used to save money and future trouble.
