    351w swap with 302 parts

    So I am swapping in a F4TE block into a ‘91 fox. I’m keeping the smog pump but I’m not sure if the smog thermactor tubing will transfer from my 302. I want to know what did you guys do to make it work in order to do smog checks.

    What's it Worth? 67 Ford Mustang Thermactor Smog System

    I removed a California Thermactor Smog System from my 1967 Mustang with a 289ci V8 engine. Is there a demand for these parts in the Mustang restoration world? Thanks, Roy

    Plugs For (thermactor) Exhaust On A 66 V8

    Need to replace the (Thermactor) exhaust plugs on my 66 V8 with something like C6AZ-6052-A. Is there an alternative, like a regular 1/2-20 bolt? I assume a grade 5 or 8 steel bolt should work, about 2" long, but don't know for sure, is it exactly 1/2-20 thread? Any suggestions are much...
