Hi guys,
I have a question for you....
I have run across a old Pro-stock style
351C block. This block has had the cylinders bored completely out and replaced with .250 thick cromoly (I think) sleeves. The block was then furnace brazed to seal up the deck and bottom of the bores. The block currently has a 4.100 bore.
My questions are, how reliable are these blocks? How reliable can they be after a few years of 9K plus drag races?
What would be a fair price for such a block in Good condition?
I really like the idea on a 4.125" bore cleveland, add 4" stroke..get 427ci.
More cubes = more good! :P

Oh, I forgot to ask, If this block cleans up with a 4.125" bore, can I use SVO "W" style head gaskets if I cut the square water holes in the front of the gaskets?

That was the "hot lick" in the 70's and early 80's before SVO blocks. I had one done for my first big inch (for the time) Cleveland, a 414. They (it) worked very well as long as the brazing was done well and you used ceramic seal. You can use the gaskets. It cost BIG money to have that done by the way. I would use it in a heartbeat.
