(1/1)

79T/Aman:
This old Pontiac is only getting faster, this past winter Sean installed PTFB true coil over front suspension set up and was in the top 5 all weekend as opposed to top 15 last year, the engine received a Holley stealth efi as well, that has made for a flatter torque curve and more mid range, it actually hurts traction as he is able to spin the tires at will anywhere on the course.
The car is still on leaf springs no mini tubs stock suspension layout, 461 Pontiac, 315/30-18 at all 4 corners.
