I had a friend call me and ask what alternative engines work well in the MGB. Being British myself I am a purist and wouldn't change it - however he does want to. He's considering a Miata engine? But I'm sure there are plenty of other 4 cyls out there. He doesn't want to cramp a V8 into it.

The 60-degree GM V6 and T5 transmission combo is a great choice. Gobs more power than the B engine, about the same weight, and an easy conversion with lots of support. Here's the one I did a while back: http://www.britishv8.org/MG/MickeyRichaud.htm

Sold it a while back to downsize a bit, but sure do miss it!

Meant to ask but always forgot; was it necessary to remove the Smith's heater box to fit the V-6? And if so, did you put a heater core in the footwell with the AC unit somehow?

It's not necessary, though it does afford more room for the dizzy. The AC unit I installed included a heater core in the evaporator housing under and behind the dash. A bit tight and fiddly on the installation due to all the hoses, but worked out very well. You can see the "manifold" for the heat and AC hoses upper left in this picture:

Now I see the heater control valve. Shoulda noticed it in the photos in the link. DUH!

Thankyou Mickey that's a great idea and will pass on.

You're welcome, and I'm happy to share any info if he has any questions.

At our age we do have a bit of slippage, don't we? :smirk:

If you want you can make a GM V6 look quite at home in an MG. This is the 3.4 in my rebodied MGA.
