Thanks guys for all the info and links to articles. I knew the benefit of 48 degree lifter bores but didn’t know the drawbacks. The one thing I really didn’t know much about was the differences between tall, mid and short decks and challenges when running one over the other.
If I decide to do this, I’ll go with a 48 degree, Siamese, 9.02” deck height block with billet caps.
I like the idea of going with a 420’ish ci short block and getting a good set of ported Victors and solid roller off I can find someone that can grind one for me.
I still have the option to get better heads on my current engine as well.
