Tech Question

eric johnson, kenton, DE, 1971 dodge dart 318

I have a 1975 truck motor that I have swapped into my Dart.The ’75 motor has smog ports under exhaust ports. Can I use my ’71manifolds? I can’t seem to find any info anywhere. Cheapest fix? Can I plugthe holes?

Eric, those were A.I.R. injection ports. Run a tap through, then use Allensetscrews glopped with Loctite. From memory, I think 1/4″-20 fits perfectly.

These are basically the worst 318/360 heads ever made, from apower-production point of view.
