Is there anything that is really good about the 351 Modified cause i know a guy that will sell me one for $200 so im not sure if i want to get it or not cause i dont know how good these motors are im used to working on my 460's so if anyone cantell me some good reason to buy it i'll prolly have in my shop in the next 2 weeks or so.
Never had much luck with the M engines, I prefer the big blocks or Windsor's myself. I guess I never explored them enough to tell you why they don't work the best, I just have always had better performance out of the others.... Oh yeah, have had a couple hard charging Clevelands and used to drag race with a Clevor.....
351M is a decent utility engine. not the best pick for a performance engine
i've had a coupla 351m's.... they're tough.... but dont push as much power... they're just made to take extra abuse
I had one in a 78 f150 that the previous owner installed a RV cam and it ran great,with 2.75 gears it got 18 MPG on the highway. Jeff
Put those heads on a windsor block and use a steet boss intake!!!!!!!........
I had one in a roundy-round truck I built. We shaved the heads .010, decked the block another .010, ran a healthy cam with a big two-barrel (mandated by rules) and headers. It had gobs of torque, and ran up front a lot of the time.
Good engines for their purpose. I bought a '77 LTD for $900 several years ago. It looked new and only had 58,000 miles on it. The upholstery was perfect. The only thing we didn't like very much was that it was that awful mustard yellow color Ford put on some of them.
I bought it from a buddy who was half-owner of a "we tote the note" car lot in Fort Worth. The car had belonged to a very elderly couple, and that turned out to be a problem. Those 58,000 miles had been put on one mile at a time. That engine was the most sludged up nasty mess I ever saw. Every time the love of my life started the engine smoke poured out of the tailpipe so bad we were afraid somebody would call 9-1-1. She was an Executive Secretary for IBM and had her own indoor parking place in a row with a Bentley, several Mercedes, and some common stuff like BMW's, Corvettes, Lincolns, Lexuses (Lexii?), etc.
Every time she fired "Ole Yeller" up in that place she was subjected to everything from giggles and exaggerated coughing fits to threats and cussing outs.
I was ordered to solve the problem immediately.
A rebuilt engine did the trick! The dang engine cost me more than the car did, but to be fair, we got another 140,000 miles out of that big barge before a gentleman who had "tee many martooneys" rammed us in the the rear.
Had that not happened I might still be driving the critter.
