Roller Rockers

[Rotus8guy]

I'm starting on rebuilding my Olds 215 block with Buick 300 heads, and I'm looking at roller rocker options.
Any experience and/or opinions on TSI, Harland Sharp or T&D from TWS, or TA Performance?

TIA,

I have stud mounted Harland Sharp roller rockers in my 400 HP 350 SBC that is in my street/strip '68 Camaro.  Harland Sharp made the first roller rockers.

Not sure sure you will see any real benefit on a 215, though.

I should have mentioned, it has a 300 crank too. About 298ci.

Sort of depends on how high you plan to rev it and how much lift your cam has.

I don't have lift numbers at hand, but the plan is sporting street use and autocross. 6500 redline.

The stock rockers can support that and lift up to about .500". If it is a hydraulic cam, adjusters aren't really needed either, just install the correct pushrods. You will need stiffer springs of course.
