1.347 Roller Rockers?

[DanLewis]

Has anyone ever installed a set of roller rockers like these?

If so, does the 1.347 lift offer any noticeable increase in performance, or is the only benefit a slight reduction in valve noise?

Thanks!

The EBay link looks to be the Harland Sharp rollers. Setting up is not a direct bolt on and adjusts like the OEM’s, many hours of fettling with to set up. The advantage with the 1.3 would only be less valve guide wear, no advantage in HP. If you’re looking for HP you select a camshaft that best performs with its corresponding rocker to your compression ratio and how the engine is to be utilized.

Talk to Len Fanelli in New York. His cam/roller set up is hard to beat! And he builds his MG kits just for the MG engine! The illustration is for an XPAG engine, he builds others. PJ

I like that the site Paul suggests sells a complete kit. Several years ago it seemed to be a fad to put roller rockers in TR6s'. Not so much anymore. In fact many have taken them out because of different problems, mainly due to valve train geometry changes.
