recently I purchased a 92 f150 5 speed super cab long box 2x4 with an 8.8 rear end. I got the truck for $400(guy was going to take it to salvage due to a broken brake line). I have been driving it for about 6 months now and it runs great, only use it to go visit family every other weekend which is about 300 miles away, I have been getting about 16mpg so no complaints there.
The problem that I have is I just bought a boat over this weekend, 19' fish and ski which is around that 3000lbs area. pulling a load like that seems to be a challenge for my engine, the suspension handles it very well but I can't seem to hold speed or even accelerate very well, put it to the floor to get 70 and hope I don't find any kind of hill lol
I have been thinking about pulling the cat and muffler to help with flow out and k&N filter for flow in. also plan on giving it a little timing bump
I have done a full tune up on it when I purchased it
don't really want to spend a lot on it as I only paid 400 so any thoughts would be appreciated
I don't know if you have the 4.9 or 5.0, but the exhaust switch would help it greatly regardless. If it has larger tires on it I'd consider grabbing a set of stock 235-75-15 tires. You probably have gears like 3.07. If you wanted to you could grab a rear from the jy to change to 3.55. You're on the right track, just keep it maintained!
