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.

 

SpeedPro 844-H535CP in Jegs catalog. 9.14:1 with 92cc heads.
$37.99 each & they are coated with anti friction stuff.

 

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

 

thanks anyways guys but ive decided to go with stock replacements to save money and the fact that for what im doing with the motor higher compression doesnt seem necesary.

 

Awwww... Higher compression is ALWAYS neccessary!!

 

In Fact, in some instances Hi Comp is more than necessary, It's MANDATORY. . . . . doncha see? ? ? FBp

 

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.
