[JEFF69Z28]

[FullTimeRacing]

mine is #3000 with me and I run (depending on the weather)10.70-11.10 running a 360 cid.big roller

I hope the T-350 is built.

[JEFF69Z28]

MY OTHER MOTOR (406) RAN 11.60 WITH A 510 LIFT CAME 10 INCH CONVERTER AND 3.90 GEARS.

[FullTimeRacing]

I have 4.56 & 30in tall tires,T-350(that is now broke) 8) and go through the lights at 7000 rpm.

I think you will need a bigger tire.

WHY?

[hammertime]

I baby them first few hits in the spring, better safe then sorry.

1st pass this year took it to 60ft, got to the trailer to check lash and found a rocker arm stud had pulled a heli-coil out of the head. Was better playing it safe..

[I972Nova]

I had a very similar 406 in my truck and it ran a best of 10.48, but that is weighing in at 2750 with me in it.

[JEFF69Z28]

WHAT TYPE OF FUEL SHOULD I RUN TO RACE THIS MOTOR? A 50/50 MIX OF 93 AND 108/110 VP RACING FUEL?

[chevyfireball]

You ever seen a Pro Mod or Pro Stock do a rebuild between races and then baby it? Don't think so.

FIRST PASS 10.60 2ND WAS 10.53 AND I SHIFTED FROM FIRST TO 3RD BY ACCIDENT,IT RAINED AND I DIDNT RUN ANYMORE.I THINK THE CAR WILL GO SOMEWHERE IN THE 10.40'S.

[dparker]

[JEFF69Z28]

What did it 60ft?
1.44

[FullTimeRacing]
