Re: SS block for sale (1970)
I think its a 454 450hp block.
It's a CRV not a CRN. 4spd manual It has no other numbers after the CRV code which means it could fit whatever you want it to fit. It was a replacement motor.
CRN code came out in 1972 270hp automatic
Tonowanda plant casting is Aug 2 1969
Install date of Sept 3 1969
!970 models were in production at that time.
