Ok , for anyone following my build..
I have a 331,voodoo cam 268/276 489/504
2200 stall
10.2:1 CR
600 edel with 107/100 jets...
dart irons. 2.02/1.60
180R
64CC

I just pulled out a cam and tunnel ram...
Need advice on a carb...
lunati says 700cfm or better..

I hate to over carb..I know I should only need a 650cfm per my numbers with math...but we all know things look better on paper than real life!

I was just reading an article on a 340 stock bore with the same cr almost same CI less cam and running an 800??

My plugs look perfect now,but I am also behind on timing a little...

Anyone DARE run an 800 on this set-up???

750 CFM from Holley, Demon, Proform.... or streeter Edelbrook ???

[tripleduece]

Edelbrock..
They are "joe" idiot proof to a degree,So thats what i got:o:tu

I would go with at least a 750. The engine is just an air pump and a larger carb will let more air in.

Dangit...lol
I should have went 800 w/ the endurashine!lol:D
I like shiny stuff...


Going by the math
CID x RPM / 1728 / 2 x VE
I should need LESS than a 600cfm:eek:

Like I said before though...some things just look good on paper!:D

I dont thinkg the 750 should kill it...I am also going to be almost the SAME jet size and spring size now too!

Go 750, she'll be fine, you can rejet if u have to, and better a tad fat then lean :eek:

[tripleduece]

750 should be here monday!:D:D:D

[gconnsr]

750 sounds good to me:tu

You'd probably have better driveability with a smaller carb, but for what you have the 750 would be better on top end.
