I have a 10,200 gen 4 tall deck block with steel caps $1,000

How bi is that I have a longblock 454 laying around

I have a Gen 4 casting #14015445 long block can you use this ?

Pretty sure this was the bowtie block I just had. It was a 502 that the block cracked, but I have practically new JE pistons, rods and a crankshaft that has never been turned that I would sell. Maybe some other stuff, I'd have to look.

I'd prefer just the block. tell me more about it and how much?

It came in my 1989 Fountain, the boat listing sayed twin 500 hp's So I had someone go throu them to freshen up, well 10 minutes into running them in the boat the one motor let loose and a rod out the side of the block. So I took this one out put to the side and bought two 502's. The block has heads on it no roller rockers, oil pan pistons rods a long block that needs to be done the wright way Give me 600 and its yours
