I posted a while back that 30 yrs ago I saw some SBC cars running in C/SM with their 4150's sideways. Don't remember the theory, but a really short stroke running low 10's and turning 9k was good enough for me :D. I'm almost positive one was a SRD (Speed Research & Development) 66/67 Nova running out of So. Penn. right next store to Jenkins shop. I'd love to find a pic of that car. Maybe one will show up on google?
