Ok, So I am going to install a carb for now intil I make my intake/FI setup. Could I get what you guys are running for jet sizes and power valve size for the Holley set ups? Im a lil over kill with a 4412 Holley 500 two barrel but its what I had lying around. I am running a Transdapt adaptor on the stock manifold for now. I thought I had this all planed until I saw Turbo farlane 200's setup and now my FI ideas have changed. So its carb for now. Thanks guys....

If you are just bolting the 4412-500 carb on without going to 68 main jets you are losing much fuel miliage. The restrictors under the power valve should be in the .052-.055 diameter, not the stock .061 diameter. The idle restrictor in the metering block should be in the .030 diameter instead of the stock .034 demenision. The 500 is a great carb but you will lose some power & much fuel economy if not jetted leaner in all areas. Once you have leaned it out then put an 8.5 power valve to prevent a lean condition on transfer from the idle circuit to the main jets

Any of the 2300 Holley carbs you have to make richer on a N/A engine, you best check your fuel pressure.. William

Thanks.... If I remember this was a old carb off of a modified we ran in the 90's so I plan on going through the whole thing. Hell, I dont even remember what it had for jets and air bleeds back then. I actually thought it was going to be overkill. Anyhow, Thanks
