rumblefish's Duster project
I must have misunderstood. I thought you were using a 318, which have really small ports and are definitely smaller than on the LD340. On that subject, I went to a swap meet today looking for........?
I saw 3, count them THREE small block Mopar intakes. One was a Performer II ($70 and dirty), one a TM5 ($100 and lots of paint), and a six pack setup (didn't even ask)
The motor I've ended up with is a (supposedly) 66K mile 76 model 318. Would have preferred something older for compression, but chiggers can't be boozers.
