565 HP @ 6700
530 TQ @ 5200
High 10's 1/4, but faster with a glide, plus much more consistent.
Them little 11.5's are gonna be tricky getting them to hook with a 3 speed coming off a brake, might try a limiter chip around 3500 to soften the initial hit.
I envy you pump gas guys, I swear I will never build another race gas only motor, if I have to go up to 600 cubes to get 800 horses I will, this $8 a gallon race gas is fkn killin me!

Goodluck Cp

Thanks for all the replys. I originally had 1.5 rockers and my local engine builder recommended 1.6. luckily the 1.5 are still in the garage.So I will definitely throw those in the track box.I do think a glide is in the near future I will run this th350 till it goes.I do run a two step initial launch set up at 4400 rpm with upper limit at 6800.i'm hopin for high tens but we will see. I will keep you posted.

That 406 I built was a flat tappet 560 and 580 with 256 and 262 with almost identical combo as yours and it was just awesome! His car is 3200 with driver with 4:30s and a glide with a 5000 stall. That was with pump gas! Dont worry, unless you live in Denver and every other thing on the car is a mess, it will run in the 10 sec easily. Ours ran high 10:60s and high 10:70s in the worst heat and humidity in Georgia. We are in North Georgia so the elevation is about 1300ft. It made me rethink my BBC combinations......like what am I doing with them! Now we had our heads ported specifically for this combo by Jon Kasses head porter so we did spend money there but the rest was a GM block and Eagle crank and Rods.
