Wow Bob. Joe Sherman another blast from the past if it’s who I’m thinking of. I raced him in my white Sport Belair at a Super Chevy event at Sears Point in the ‘80s. He had a red lightweight ‘62 Sport Belair. Wondered why ever happen to that car?
Re the X-Rams. I don’t think the 50 is accurate. I could be wrong. I had three in my collection at one time back in the ‘80s. I had seen probably 4 others at various regional swapmeets over time. I still have a polished M/T that was on my flat bottom.
If it made that much horsepower I’d sure like to see the dyno sheet comparisons.
I had an as cast crossram that had no PN or M/T on the casting. Thought it to be a pre production prototype. Never saw another that way unless it had be ground off.
I can say that these manifolds a ridiculously heavy, a PITA to access the center bolts. Definitely designed for race applications. When in High school I took a M/T off my ‘61 Impala Bracket car and tried it on my 409/409. It didn’t like it a bit. Totally undriveable corked up. Poor low/midrange, cold blooded. Just
A miserable experience. But I was 17 at the time, the engine over carbureted and I was trying to look cool at school. No go showboat at that point. The factory quads went back on the next day.
