Hey I have a 78 "I believe" 440 block out of a motor home and it has hourglass shaped collant runners in it and can only be bored .030 over for fear of thin cylinder walls, and I am looking to get 600 horse out of it. I have been looking at a stroker kit but dont know what the best way would be. Let me know what you think I have read some other responses and you guys know your stuff........ thanks.

 

I'd probably ask this over at ramchargercentral.com as there seem to be far more oldschool guys over there than there are here.
