I remember seeing pictures of Mike's truck when it was all white and had 31" tires. It either had a 20R or 22R and he converted it to EFI and said it screamed. Way before any 4.3....
Yeah, and how much coin did he lay out?
"22RE improvements" don't get a lot of bang for the money you put into it. I don't even want to think about how much money I dumped into my old 22RE powered truck to get a bit more performance.
