What is involved in 2.7 to 3.0SC swap?

[racer_X]

I have a line on a rebuilt '83 SC motor, what is involved in swapping out my '77 2.7 CIS for the 3.0 SC motor?

I know I need the SC tach and to improve my oil cooler : ) but that is the extent of my knowledge gathered in some quick searches. I am about to leave to take a look at it.

I am not sure if the motor has the fuel injection system on it, if it doesn't should I or can I use the '77's CIS?

Thanks in advance for any useful information!

Considering the amount of work this would involve, why not find a 3.2? I suspect the motor is the least-costly element of the conversion (in terms of both time and money).

Blah blah resale blah just drive it...

I did this swap years back. An '83 will have a lambda box, cat, 6 pin cdi, internal reg alt., and the harness to go along with it. To minimize confusion, downtime and to see full benefit, I'd only do a full swap including exhaust and no mix 'n match. A fair amount of work if you're doing it. JMO, I wouldn't take down a healthy car for this.

Thanks guys. I'll take the advice and drive it instead of swap it.

Someone in Buffalo, NY was selling a "rebuilt" SC motor for $5K on Craigslist. I drove out to take a look. It didn't have the wiring harness or the lambda box or the injector lines. While the motor may have been "rebuilt", it didn't appear to have many "new" parts, so I passed on it. I figured why pay for another project.

Outside of what I mentioned, it had everything including the exhaust and cat.

So what's a core 3.0 SC motor worth?

I was thinking that $3K was market value for a rebuild-able core, but these days anything 911 seems to command a higher price than I expect.
