Been discussed a few times here on board, but I don't have first hand experience.... They are listed as different in the '65-'72 Master Parts Catalog... I'm guessing all from '73 up are same(I don't have the later catalog)...
How mutch wider is a mustang rearaxle. Would i got problems later with the width if change to a mustang rearend. Saw a tread earlier about spacers what made the axle 1" wider on bouth sides, what are you guys thinking about them. Must be the easiest and cheapest way to convert from 4 to 5 lug.
Since you're limited on engines, you should turbo that six. Turbos are plenty over there, and I'm sure you Fins can think of something. I've seen crazy turbo tuning in inline sixes, they can wail!
Not all inline sixes are created equal. Those old sixes that Mavericks & Comets had are best used as boat anchors. A modern six would be a different story.
I have to disagree on that. I seen these little sixes, with a little work and money, can spank some 302's.
I'm currently contemplating a 6cyl swap as well. There are tons of inline 6's that make 2-3 times the power from factory. Bmw is the inline six of my choice, slightly biased, because they are relatively same size and the power is very good for its weight. A 3.5 Bmw engine of the 80's made anywhere from 180-210. The only downfall is they're canted, and maybe won't fit. Japanese engines are great as well. the 7mge, or 1jzge, both make great power stock, and are dohc. Carbs can be retrofitted, so it's possible to do without a computer
When Ford introduced the 250 in '69 was stated it would accelerate evenly with a 302 to 50mph... Only fresh 250 I've ever driven was a new '72 Stang with three speed, was fairly brisk in 1st & 2nd, had enough torque to easily break the RR tire loose on a quick take off... Would have no doubt been quicker in a Maverick but I dunno if it was available with a stick, in the earlier years only automatics were avail(at least '71)... I know the 250 could be had with a stick by '74 as I owned one but it was getting a bit tired by the time I got it......
For the price of making a 6 go you could bolt in a mild 302 that would be faster! I agree that a 6 can go but the cost is high! I had a friend back in the 1970's that run a Maverick with a 300 ci 6 that run into the 11.00 second range at the drags but it was not a lo cost car!
I can't see messing around with the old 200 or 250 from the '70s. Modern 6-cylinder engines are very good performers, and if a V-8 is not attainable, that is what I would recommend.
The old Ford 2.3's are VERY good engines with TONS of aftermarket support. With todays newest tech and computer controls you could easily turbo one of those well into the 400 horsepower range and still get decent mileage too. Ford sold those things just about everywhere too so there should be no major shortage of donor cars to get er' done.
