I'm glad this topic comes up from time to time as I have been toying with the idea of putting a big block in my 69 K20. I dont want to do it if it means messing with the frame rails, hacking up firewall, etc.
eedgell, love that truck man!!! The BB swap looks like it could have been factory done, nice job!!
What year BB's are you guys running? 2wd exhaust manifolds? Any oil pan clearance issues? Any info you guys who have done this swap have and would like to share would be great, thanks, Mike.
