V8 on 73 up k member?

Does any one know how to install a 318/340 on a 73 up k member. Schumacher doesn't make mounts anymore and the ones they did make were for 72 and earlier k member. I don't want to change the k member if I don't have to. Thank you in advance for sharing your knowledge that's what keeps this hobby alive. Car has 73 slant 6 k member in it currently.

Take a look at this threads and the link to Engine swaps, give them a call so you can find out when/ if they will be bringing back the spool mount slant 6 to small block conversion mounts.

Schumacher Creative Services

These are the conversion mounts you would want to ask when they will have them again, since I think they are still out of production.
'73+ Poly Spool 273/318 or 340/360 Replacement Kit

These guys are the money behind the product now.
MOTECH Performance

Original company and product that made the mounts available on their own, now still involved, but not on their own.
'73+ A, B, C, F, M, J-Body

I would contact them both, to see what they can tell you about availability, good luck.
