my last build was a 496" raised deck. Crank was a k1 4.150 stroke with 2.200" rod journals. The rods were 6.800", so the rod ratio was 1.654". The compression height on the pistons i ordered was 1.825".
I used the 440 block, because that's what i had. Seems like a lot of people say to go with a low deck when building a big inch stroker, because of the supposed block strength vs the raised deck... Whatever. Guys back in the 60's and 70's were making a ton of power with 440's and they didn't shatter like glass lol.
