RE: IAC with B303 Cam
You should be able to set idle and solve the surging/unstable idle problem w/out major modifications. I've set FMS alphabet cams (B, F, E, X), Stg 1-2, Schneider, CompCams....58, 65, 70, 80 mm TBs, w/out any comebacks.....all you have to do is use the free tools the EEC-IV system has, and follow the correct calibration procedures. Doing the gasket matching to the IAC/TB transfer holes is a good tip to follow BTW....but you need to make sure the EEC-IV system is failure codes free (from the important ones) first.....

RE: IAC with B303 Cam
i did get rid of it about 2 yrs ago but it's just getting old to let it warm up to idle, once it's warm it idles fine, now that i know there is another way to try it im going to give it a shot

Ifyou don't want to use the dremel toolto open up the holes you can get one of theseadjustable idle spacer kit on ebay

I had problems with idle too after I got the 351W motor, bought this spacer kit it's fine now easy to adjust.
