I have D1VE block bored. 30 over PI heads getting ported,rpm air gap intake,headers,exteme 4x4 cam 2300 stall,running 35 inch boggers. wondering what carb would be best don't want to have to set it all the time, still looking for some preformance and also wondering if i should switch my cam. going too be driving this truck sometimes, also running in the odd mudd drag nothing too drastic.Still want to beat the chev's

Holley 950HP with standard down-leg boosters; unless you need a choke.
Whether or not to switch cams will depend upon which 4x4 cam you have now...
