I have two sets and it's for a street motor and I am an old, old school guy. This is a nostalgia build, the 305 was only produced in 1970, newer technology is not the point with this particular project.
The 305 Trans Am racing motors where never "produced" by Mopar, Kieth Black Ent. destroke the stock 340 cranks to make them that C.I. with the T/A, AAR blocks is what I remember being told back in those days by employees at All American racing and Larry Shepard at one of the old Mopar drag seminars
Thinking now about Ma Mopars relationship with Moldex back in those days maybe Moldex made all those cranks to start with so they would work with the stock rod journal sizes instead of using SB Chevy rods and bearings
