I have my eye on a 1967 250se 2 door coupe automatic that I may buy and do a restoremod. It's in ok running condition but definitely needs work. I want to make it into a daily driver so I'm thinking that the only mods I'll do are to swap in a 280se motor and rearend gear cluster. If possible I'd like to swap in a DOHC 2.8L with electronic injection, but I don't know if this is feasible.

What is the newest 280 6 cylinder I can bolt in without any major modification? Do I need to swap the tranny? And am I going to find one in the US without breaking the bank?

Also, where is the best place to buy parts for this car here in California? I'm sure I'm going to have to replace most of the suspension bushings and mounting bushings at least.

Any help or ideas are greatly appreciated. Thanks, Jim

Parts are pretty easy to find. try peachparts.com, Napa auto parts, autozone, the like. Doing a general internet search for your car +parts will yield a lot of places. The stealership also has parts, but I always steer clear due to cost.

Welcome to the forum, by the way.

Either fix the existing engine or find the M130 280SE engine. The car's value will be be adversly affected by swapping in a different engine such as the M110. (it's your car do what you want though).

Thanks for your reply. You're right about the affect on the value but this is a hardtop coupe and unless I do a full frame-off restoration the value is probably never going to be more than $25,000 or so. So, I figure I can make some mods upping the hp and gear ratio making it better for my freeway driving, turn it into a daily driver I'll keep for quite a while and not worry so much about the market value. I'll keep the original motor and tranny in case I want to sell the car later as an original. That's the reason I'm looking for 280 that will bolt in without any major modifications.

Ideally, I'd like to get about 200hp and 20 - 28 mpg. That's why I'm thinking about a DOHC 280 electronic fuel injection. I understand that a few of those produced about 185 hp out of the box. I just don't know if there is a 280 DOHC I can bolt in. I know I can bolt in the differential gears and up the ratio.

Why not going with a 5.6 M117 alloy block V8? They are plenty around, reasonably easy to fit, not heavier than the original iron block L6 and can be converted to Megasquirt. It has been done several times and is quite well documented.

280se motor is a good idea,
I have done the 250 motor with auto and there is a good reason they went to the 280 motor. They even hung a throttle step-up for the power steering pump burden (250), and then a auto trans and AC make it a underperformer, rectified by the 280 motor.
Once the 250 has accessories hung all over the motor it lacks power.
But a 250SE 4speed manual, no accessories is a great engine trans combo.

I have a motor/trans available
where in CA are you?
