Just going through some of my PDL Mustang stuff, and came across a photo of PDL 1 and 2 together in their yellow/orange livery and it got me thinking.....

What engine combo would PDL 1 have been running at this stage?
Previously, in it's 'electric blue' guise it ran the injected 351C Gurney Weslake combo,
but this engine ended up in PDL 2.
So what engine did PDL 1 have fitted at this later time?

I believe this was when a Baker was driving PDL 1, with Leo driving PDL 2.

Anyone know?

Cheers.
