I've used them in several engines and never had a problem. This is the first time I've heard someone say they were "too heavy". My 400 Pontiac spun to 6500 RPM on a regular basis and they didn't go flying out of the block or anything. :)

Well not "to heavy" to use, but he think that I can gain much if I go with lighter pistons, like SRP/JE.

Thanks for your feedback :cheers:

A lighter piston is better, as long as you don't give up strength and durability in the process.

I used them in a 406 with no problems. They are a heavier piston than the JE or SRPs, which will cost you more. As long as the rotating assembly is designed to work together it should be OK.

There are a ton of people using the TRW/Speedpro forged pistons out there.

Good point about the rotating assembly designed to work together .
Could there be some issues with a SCAT 9000 crank, SCAT ibeam rods and those TRW pistons?
