Ditched the Weber 44 IDF's for a Mint set of 45 Dells. Now i need a little help getting a good base for jetting them.

74x94
110 cam
40x35 p&p heads dual springs
1.25 ratio rockers
8.9:1 comp
1 5/8 header
019 dist
12lb fly

Carbs: 45 Dells with 36 vents, 70 idle, 200 air, 162 main,

Got a buddy who has a A/F meter on the way so i need to gets the base jetting on the way. Thanks in advance.

Id start with 60/150/200s. Its odd that you have a mint set of 45 dells and they have 36 vents when they commonly come with 38. 162s would be better for 38 vents.

They did come with 38's but i knew they would be too big for the 40 intakes so i swapped them out. so 60/150/200 is my baseline. new to dells but if i remember right the jets come in .5's as well or am i wrong.

All jets basically come in .05's. IE: 155 = 1.55 . Dells come in odd sizes like 48 or 52 idles, 118 /122/162 mains and so forth. But as far as a 55.5 don't believe they come like that. Dells seem to like a little richer on the jetting. Aftermarket drla jets are not accurate. Cbperf ones are on the .02/.03 size bigger from what I've measured.
