What I have is a 1986 F250 HD 4x4. It's got the 351W and 4.10 gears and a 4 speed that I believe to be a T18 (heard that the T18 only had the pto cover on the passenger side and the fact that it will only go into first if I'm at a dead stop). I'm considering a few different things to change on it. As it is I have a better muffler but it's a lil small IMO with 2.25 in and out. A previous owner put a holley 4160 carb on it (found out it wasn't the 4180 during the carb rebuild), and removed all the smog stuff. I thought he had removed the catalytic converter as well but it seems as though some of these trucks never came with one.

Ok..so right now I lookin at maybe some 1.7 ratio roller rockers, headers (either shorties and a borla y pipe or long tubes), edelbrock rpm air gap intake, or an edelbrock exhaust. I am also considering a full msd ignition setup. Also, would some ported E7TE's be a good upgrade for this truck? I intend to eventually go with a 408 stroker but that's hard on a student's budget so that'll at least be a couple more years. Any and all thoughts and suggestions are greatly appreciated. Thanks.



ps..funny story..I bought this truck b/c the 03 chevy my folks basically gave to me started falling apart...sadly I didn't stop with it until after i dropped some perdy good $$ into it...live and learn I guess

 

If you could afford it, I would change the heads to the aluminum edelbrocks with the bigger valves and ports to go along with the intake manifold. Keep the carb you have for now.

 

I'd stay with the 2.25 exhaust, people in the Exhaust forum are knowledgeable in this. You might find the Small Block Engine forum helpful, too.
