Changing camshaft on MAF, OBD-II 300.
I'm planning on towing with my 1996 F-150 and I wanted to know if it was possible for me to get an aftermarket camshaft for some torque and a ''lopey'' idle. I've heard lots of bad stories about SD trucks with cams but I haven't found much about 1995-1996 MAF-equipped trucks.
Would I be able to run a COMP 260H or 268H without any vacuum issues?

I think a cam gets lopey at idle because the exhaust gas backs up into the cylinder on overlap, causing slow burns, mis-fires, and inconsistent cylinder pressures at idle. This will no doubt be read as a misfire and trigger MIL lights and codes in the computer. Shoot for an EFI friendly cam and accept the idle you get, which will probably not be much different from stock.
A better exhaust system will let others know engine work has been done more effectively, methinks.
