81 f100 engine specs and questions

hello.. i jus got a 81 f100 inline 6 4 spd and i was wondering if anyone knows the specs on it hp/tq and city and highway mileage, and good/bad comments about them... it seems like a dog going up, anything i can do to make it pull a little better.. i have a all forged 351w settin in the garage but i dont wanna put it in cuz it'll kill me on gas the way prices are..
thanks

I don't recall the specs for the 300 in a carbed form, but it can be made into a real monster for power. www.fordsix.com will fix you up in that end. Milage can be from 10 to 20.

Welcome to the forums! Next time post in the pre 97 forum too.
