I am excited to find this forum. I recently purchased an 85 Scottsdale 4x4 LWB. The truck has 33 inch mudtires on stock rims,which is fine for me,this truck is going to be mainly used for hunting and running around on the weekends. What I'm having issues with is the truck is supposed to have a rebuilt 305 in it with a 650 cfm Edlebrock on top and a recently rebuilt transmission. The truck does not seem to have a lot of power and it also does not seem to like to go above 55 mph. I've been told the 650 cfm is too big for that motor,but I'm also looking into getting a 350 put in. I had a 99 4x4 with the 5.3 so I'm used to being able to get on it when I need to. Forgot to add I'm from Benton,Arkansas.
