Hey guys,

I am building a 350 vortec in place of my 305 tbi right now and i was wondering what kind of carb should I go for? I am looking for something that will give me good driveability and am not afraid to tune.

These are my specs so far

cam: LT4 Production Cam duration at .050" is 203/210 max lift with 1.6 ration rockers is 476/480 115` lsa

engine: 1998 350 bored .30 over, 081 cylinder heads with enlarged cc's (around 63cc) and 1.94"/1.5" valves . I am going for 9:5:1 compression.

stock bottom end, machined stock crank, dished pistons.

I am going to be buying a 1998 S10 4.3L 2wd stall converter(2200-2400) and transmission cooler for a 700r4 and a corvette servo. Already have a shift kit in it which allows for 1-2 wot shifts.

Thanks in Advance !

hey thx for the reply, i was also thinking of a carb with mechanical secondaries but wouldnt the gears that im running cause it to bog. Im running 2.73 but i will upgrade once the time comes.

 

It's the torque converter stall speed that prevents bog, not the gears.
