dang matt, sorry to hear bout the issues. i know getting some HP out of a 6cyl will always cost money. making them flow better and oil better(ie. heads,crank,valves,etc) will cost time and money. you can always make the exhaust better yourself, but that will cost whatever the parts are(ie. prebent parts,muffler,header) i used to have a 1bbl to 2bbl adapter...but im sure it wont work as it was for my chevy 250 6cyl i once had years ago. maybe you can get a wide band O2 sensor installed so you can read rich/lean and tune the carb better.

is the intake built for a 1bbl or 2bbl? i thought a stock intake would be 1bbl. if its running rich, im sure there are tricks to getting more air in the carb...been a long time since fooling with a 6cyl. as for the gears, i would look hard for some 33" tires...dont give up the 4.10's. you not gonna get any serious HP out of that with out major money. also make sure the drums arent too tight...i know i had to back mine off a lil just so the car rolled alot easier. those MPG numbers arent that bad...thats what im getting. Im sure you can do better. are ya on the fordsix site? im sure they can offer better/improving info there too.

also, there is a wide ratio 4 sp...kinda like a np435, but its 1st was normal and 4th was a OD. that might be a cheaper option, not easily found...but less expensive than a true over drive trans like myself. good luck buddy
