Hi everyone, I'm new to this forum so here it goes. I have 3 engines and transmission laying around in my garage and I dont know for sure which one to use. I have a 351W out of a buddies old derby car that only lasted 1 minute because of a carb that was on it was way too big, a 390 that was out of a totalled F-1 pickup some guy had put in for a unique combo, and a 400 out of an late 70's F-250. I would like to put one of these into my 1966 Ford F-100. The truck has no motor in it and i would like to keep the body and interior the same but what i really want it a slightly tuned up weekend driver! My plan would be to just enjoy the truck for awhile and then someday i would like to do a full frame off restoration or just keep as it is and start another project like a galaxie, torino, or a comet. I stop dreaming. I have heard that the best power/money engine is the 351. What are your opinions and what kind of modifications would you suggest i do. I would like to do a slightly lopey cam (so you know its there at idle), and different intake and carb combo and probably headers too. Which engine to use and what to change is what im wondering. Thanks for your help!
