Fran,your not thinking big! check out my new B-702 at
www.Blastolene.com I can let you pull a mold! (sorry I do not know how to post photos) But supplying customers with 702 cu.in v-12's could be like ordering a zf from RBT.

PS. do you still want me to make some aluminum roofs for 40's? I now have time while I wait for a Trans for my 40.
