Did test run today,6 miles around the country block. GREAT RUN, Except for carb adjust and timing issues. Fresh co0olant just added, temperature stayed at thermostat ed 180 degree, Oil pressure stayed pegging the old oil guage at 30 pounds. Pulled back into shop and a puddle showed up under truck. Rear driver side frost plug had sprung a leak. I want to install a temporary expandable plug in the leaking hole to try and get me thru summer. Question # 1, When I ask at parts store, What is the diameter of the frost plug holes? Question # 2 Does anybody have a pair of Fenton's for a 235 on the shelf. Would you PLEASE confirm the exhaust diameter to be 2 inches AND are the Flange bolt holes 3.25 inches apart. The shop making my exhaust needs these measurements to make me some exhaust pipes so if I can go to a car/ truck show next saturday. I would be forever grateful Thanks, Jerry

It held for awhile but once it ran under pressure for a short time "pop" and out it came, along w/all my new 50/50 anti freeze. Wrestled a new steel plug back in and to my knowledge it's still holding.
Can't help on the headers, good luck.

Last time I asked at napa about them they looked at me funny.
Wow I found one I still had, made by Dorman products
Pat number 3361288 I went to their site and nothin. That is typical anything that works good they stop making it.

As for the "freeze" plug all I can add is that I've never seen a temporary anything that was worth a bucket of spit. Just fix it right and be done with it. | | |
