Volvo MD7A replacement.....

I have a '79 Cal 31 with a MD7A I want to replace.

I came across a Universal M20 without transmission. I know those to be pretty good motors. Any chance the transmission of the MD7A will fit?

Any other suggestions welcome.

Chances of the transmission fitting? I'd guess... none.

Why don't you look around for a re-conditioned MD7? It'll be far, far cheaper to replace 'like-for-like' than go to something else (because the bulk of the change-over cost is the gear associated with the engine and not the engine itself). For this reason, if they really want to do it, most people select a brand new engine.

Re: Volvo MD7A replacement.....

If the M3-20 is a good engine, it will be much cheaper to fit a new transmission like a Technodrive TMC40 that to do anything on the old Volvo.
This way you will have a current engine and transmission instead of something that is obsolete with hard to find spare parts.
