48 degree r3 block
If it's not too much trouble to ask, Does he have any of the 420 intakes to part with?
In the R3 blocks the short decks can go over 440" with a 4" stroke. Pretty wild stuff, lots of potential in these motors that 80% of mopar guys are scared (for lack of a better word to touch) they are big block killers.... FACT
I'd really like to do a max effort build with my B body, I know of an aluminum block and some pro stock W8 heads, that could get very powerful very fast
