What a suprise!

That is a nice surprise to find, congrats!

Back in the mid 80s, I took a /6 and 3 speed out of a 70 PCP Barracuda, and had purchased the whole drive train out of a 70 Challenger from a salvage yard. I put X heads, HP manifolds and an LD340 on the 318. It ran great!

I thought the $70 I had to pay for the manifolds was crazy, and the $90 for the 70 340 air cleaner was rediculous.
