Which rockers?

[aaronk785]

I'm getting some 1.6 roller rockers for my 340. The 2 i am looking at are the PRW ss and mancini aluminum made by HS. These will go on a solid cam with about .560 lift with the new rockers. seat pressure is 145 and open 350. Thoughts please. Might step up to a roller later but nothing radical. 200 seat 550 open.

Can't say anything about the PRW's but I have been running the Mancini 1.5 ratio for 2 race seasons and haven't had any issues. I would expect the same of the 1.6. Mine have been on 2 sets of head's, speedmasters and trick flows and a .590 sft cam.

PRW. Call Mike at B3 racing engines and let him fix you up.
