All you performance carb experts out there.

Need baseline jetting for startup run in (so I don't wash the oil off the bores)
383
Holley 4150 750HP DP
195 heads.
11:1 CR
847 cam 234 / 234 540 / 560 lift
open headers

 

i'll just throw a number out there.. 80/81 with NO powervalve, 74/81 with PV..

i run an annular 750 demon with a PV up front so my jets are 70/79.. 385, 10.65:1, 306S cam(260/260, .592/.555), crap 200 heads, shiftin at 6500.. i might try 72/79, possibly 72/81 eventually..

 

when i built mine i was afriad of getting it too lean. so i went went 83 all around. since then i have went back to 81 all around. no power valves and 1:1 linkage. i have a 383 with dart 230 heads 750dp.

 

whatever out of the box jetting is should be close. Get perfect jetting by using a wideband from a buddy.

 

73/82 with a primary power valve only.

 

Thank you kindly gentlemen.
Has 73 / 73 stock so I will open the sec up a bit

 

Do you have a secondary power valve? 99% of carbs out there don't... if you dont, you want about 8-10 jet sizes higher on the secondary side compared to the primary side (assuming the primary side has a power valve).

 

Has a PV in the sec side ; unable to get metering block off to determine size.
The "non stick gaskets" don't work ,(Brand new , never had gas in it ) don't want to butcher carb trying to crack metering block loose.

This is a -2 model , the online info only covers the original and -1 versions which are listed as 65 PV on the primary only.Carbs with 2 PV's have the sizes listed.

 

non-stick gaskets are non-stick, you don't install them dry, spray them with WD-40 before puting the carb back together and they'll come apart then.
