Ok, back to what I have said many times...tuning without a 02 is like pissing in the wind ! if can run what seems to be fine and still be lean enough to kill it quick. find a way to put a 02 just for tuning, I would look up the carb specs on holley's site and jet stock and go from there..

Alaways good to have also. I'm not 100% sold on them alone however good to have and are relatively inexpensive. Call me old fashion I guess. Pretty soon we'll be able to sit in a chair with a 12 pack and watch droids assemble our engines also. I'm gonna make sure and have my 12 pack in bottles so a can throw the empties at those stupid things. Lol.

Since you have dry exhaust, could you use a tailpipe clamp on for wideband like this ?
If your tails are low enough they hit the lake/ocean , then you couldn't of course. You don't wanna drag or submerge the outside of the sensor in water.

Ok so i have my boat ready to hit the lake (sunsation dominator). I need a baseline jetting number. Holley 4160 750 with metering block conversions done. Engine are 489 strokers with air gap intakes, l29 vortec heads, xm284hr cams, 9.4:1 compression, gil dry exhaust. Also do i need to stagger? I was looking at hp500 jetting as baseline but i know that is an 800 and from what i understand only staggered due to dart intake. Thanks in advance.
