I remember this truck from 1995 in Sault Ste. Marie Ontario.
Owner was Lee Joliceur. He took me for a ride, it was pretty awesome, fast truck smoke the tires for a block
It had 4.56 gears, 3500 stall 727 with manual shift valve body. 440 with closed chamber heads, 509 Mopar purpleshaft cam
Edelbrock dual quad with edelbrock 625 carbs( which he sold me)
Centerline convo pros 15x12"?, exactly how it looks in your pics
Mickey Thompson hot and sticky I think the tread was 15" wide
If I remember correctly, his father was the original owner of the truck and they put the 440 in it
He said he blew the tranny once as he took it out on the highway, ran out of gas as it was revving high with the 4.56 gears it had, and his buddy towed it without removing the driveshaft and overheated the transmission.
Is your truck for sale by chance?
