I was watching one of the POWERBLOCK shows (HPTV) recently where MIKE touted an external jet adjustment block from PERCY'S PERFORMANCE.
I have been reading some of the threads where guys were doing multiple jet changes to get rid of a bog, to rich , to lean etc. This METERING BLOCK might be worth looking into for an easier dial in.Might make the search for performance much easier.
SUMMITT has them for the HOLLEY 2300/4150/4160/4160hp CARBS.
I am sure that there are other venues where they can be purchased.
WHAT IS YOUR OPINION OR EXPERIENCE?
