Jim,
Being that this is the Penske car from 1969, would I be safe in assuming it has the 5.0 liter smallblock Chevy?
What was it like to drive compared to J6? Does it handle noticeably better on the track? Did you take it out on the street much or is the rear visibility too bad to make it worth the risk?
The IIIB was certainly a large step forward from the Mk1 and Mk II GT40s, but I’ve always wondered how it would have stacked up against the Mk IV.
Obviously dropping from the 360 to the 302 would have made it underpowered compared to a MK IV, but with the earlier 360 I suspect it would have been an interesting match-up.
