ok... ive been researching on some turbo kits you can get online but i cant figure out what do do with my intake... do i stay with the carb or upgrade to efi... its a 1968 gmc 350 banks has a twin turbo kit but there is no help for how to set up your carb for forced intake here is the site

They are using an accel DFI.
Modified to see boost.
They say you cannot use a carb

 

thst would depend on whic kit you bought.

The first kit drew thru twin 850 Holley DP's, then switch to a blow through hat.

IMHO call Gale. 20+ years ago he was willing to talk on the phone.

 

i cant beleive you are stumped on how to boost it.
Just because its has a carb on it.Anyway if you interested in running a boosted carb let me know i will enlighten you an how to do it. I could even send you a already modified carb for 12psi boost with a bonnet.let me know what you wanna do?

 

what kinda carb is it. what cfm? how much :-p

 

Yeah if you need some tips on how-to just ask.
I modified 2 carbs myself.
If you're using a 350 Engine no bigger then 650Cfm.
The best if you use a Holley DP
