Topic: Anyone run TRW forged 750 pistons?or Hi compression 750 on the street?

[754]

Found a set of TRWbStandard 10.5-1. Pistons for a 750.
Just wondering if anyone had run these before ?
Or ran high compression 750 size on the street, with big cam 315 and maybe a bit of porting and Webers ?

My 836 pistons are TRW, but I think are higher compression than 10.5? I've got pics of both somewhere.. You MUST check for adequate valve clearance on the exhaust side.

The pic of the new 3mm over piston is courtesy of Jaguar, and is 10.25:1 or 10.5:1. My 4mm over pistons appear to have much higher crowns. Note the "eyebrows" where the exhaust valves were hitting the pistons.
