I just put a weiand street tunnel ram with two 450 holley's mechanical secondary carbs on my t-bucket. The motor is a stock 350 with a crane 274H06 (.450 lift,218@.050,106LSA). It has a 2500 stall and 4.11 gears and weights about 1800 pounds. I have a lean hesitation when I floor it then it takes off. I know people have this problem do to no rear accelerator pump. Any suggestions how to correct this? Do i start with bigger squirter's ,50cc kit or accelerator pump cams? Or should i ditch the 450's and run 600's vacuum secondaries. Thanks for the help!
It has a stock gm points style distributor with the petronix conversion done. I put the lowest tension springs in it with the stock weights. I'm running 38 degrees total timing at 2500rpm. I just checked the accel pump cam on the carb they are pink in color. Should i convert the carbs to a 50cc accel pump kit? Thanks
Ditch the 450 holley and get 465VS List #1848 or 390VS List #8007. Your bog will out the window. For a T-bucket, 600VS may work OK. Just a soggy low end.
Update - I locked my distributor at 36 degrees,changed the accel pumps to 50cc and put in size 40 squirters what a difference no bog! Can i leave the distributor locked i have no starting issues with it. Thanks for help guys!
