The V8 Owners Forum -

Has anyone fitted a roller cam with roller hydraulic lifters and roller rockers..either sets from TRS in Australia or TA Performance or TWS in the US. I'd be interested in any feedabck regarding reliability, ease of installation, spring rates, lifter bore wear (either due to spring rates or extra lifter length) and lubrication via the pushrods.

All kits look well engineered but they dont seem mainstream yet, probably because of the expense.

Thx in advance..

I’ve got a roller cam in mine, but mines a solid roller !
I bought it from TRS as a full kit, (springs included). My TA heads came set up to take the lift from the roller cam

Thanks..A lot of my question are on the heads..the stronger springs and the new installed height mean deepening the valve spring seats..and using spring locators.. however by using TA heads you've not needed to worry about this.

I rang TRS up, really helpful, used a “normal” flat tappet cam to start with, then switched over to the roller,
