Hi, I have been browsing this forum and have allready picked up some GOOD info. There are still some specifics I have ? about. My 350 isn't radiccally built, just a few extras. One thing I'm wondering is, I had a big hesitation on take-off-not stomping it but goosing it a little so I put a .035 nozzle in place of the .031 that came on my holley 600cfm with vac. sec. Doesn't stumble quite as bad but still hesitates. Have a summitt cam-204*in- 214* ex, lift is .420 in- .442 ex. @ .050. Do I need to step up to .037 shooter to get rid of hesitation or am I looking in the wrong direction?Motor was just bored .010 for rebuild 2 yrs. ago with Weiand intake, Hei dist. and Accell coil. Also thinking about roller rockers to replace stock 1.5's. Not an expert but not total idiot on motors . Anyone got any thoughts on where I should go from here?
