CK and his 55Tbird (3/8/2014)
Apparently the trick is to heat the cast to 2-300*C during and after welding. Hence furnace brazing.Another option could be to remove the cylinders and recess the base for a new cylinder to be housed, and at the base sealed by some form of gasket/sealer.
And having the deck removed then a new deck could be used with a recess to house the cylinders again like the lower cylinder. The deck plate and cyl. could then be held together by studs through to the crank portion of the block/ head bolts. 3bond or some sort of sealer could be used at all the new joining areas. Aluminium cylinders could be used or steel etc.
Imagine 4.4" bores/3.3" stroke - 401CID I read that Mummert was considering making a block to match his heads!
I also read that the Crank shaft is rated to about 400HP I wonder how Ted's 500+HP engine treated the Crank?
CK, unfortunatey all of that theory s not actually practicle on y blocks after youve bored block to fit 4" sleeves, other thanf/brazing the deck. There is no room or material to do it Ted, Tim and i have tried it with no success so far!. Gart Croan is trying for new cast block with big bore, not john. Teds cranks are by Moldex usually, All of the above are beyond the financial reach of most of us.
