.585/.600 flat tappet
109 LSA
104-105 ICL
8” convertor
3.54 gear
9x28 radial slick

It’s a 10.90’s car @ 121-122....hit 123 once

Be neat to see what yours does with the TF intake.

Mine liked going from the 2D to the M1 with the -1 heads.
I had to get the flanges welded on the M1 to cover the intake ports on the -1 heads.
Love to get my hands on a 440-2 / 4150.....the 440-2 / 4500 i have seems huge
