Quest for 7's in the 1/8

3.55 or lower gear in that heavy truck.
I had a 78 D150, 3.55, 904, 14 inch rear wheels 8 1/2 inches wide with soft cheater track radials, a 360 with headers , J heads cleaned up making near 345 to 360 hp. 7. 21 fastest pass using a traction compound off a foot brake, just a 2400 stall out of a 4x4 truck. But remember I was pulling a .420's lite... truck was just to heavy.
Be careful with twist, broken shock mount and twisted frame near steering box.

Now that trans and 360 in in my 66 early A Plymouth sedan .
Lift the front as much as you can and lower the back to help with weight transfer.

Just an old Arkansas Hillbilly enjoying our 1/8 mile track for the last 40 year.. :lol:
