Holley 800 cfm MODS

[TONY GTS]

my carb is a holley 800 cfm, list # 4780-5

i bought the shiny finish holy main body : http://store.summitracing.com/partd...&N=700+4294858091+4294858063+115&autoview=sku

im rebuilding the carb right now.

i have a question,

the Primary jets in my carb are 78 & the secondary jets are 80
my carb is equipped with a 30 cc primary pump & a 50 cc secondary pump


the main body came with 72 Pri-jets & 84 Sec-jets

which jets should i install?

should i leave the 78 pri-jets in and change the sec-jets from 80 to 84?

i stuck the stage 2 powervalve in from the kit & used the jets from the kit

its a warmed over 440 & the carb works great with the combo

id say read your plugs after a run . If you cant do that stay with the stock jets or a couple sizes bigger

definately, its better to be rich than lean but in between is perfect
