a guy brought an exhaust manifold into Harolds shop yesterday to get it welded. it was an exhaust manifold off a '64 Ford. 429 ci. the wild thing about it was, it was a ...cast iron...long tube header...they came stock only on the '63-'64 429s.this thing must have weighed 50# (just 1) someone, for some reason, ground a hole in the top of the rear tube... Harold recomended he take it to the machine shop we use. they weld cracked heads and manifolds. i should have gotten a pic. ...Frank...
