Tunnel Ram...

[aaronfurlotte]

I know this was brought up before but I can't find the thread. Would a tunnel ram and dual 4's be ok on my 427 powered '37 Chevy?

Last time the subject was brought up, there was a common consensus that the dual tunnel-ram intakes started appearing sometime around late '68, but more or less exclusively on ProStock and similar big-budget drag cars.

I ain't nobody, but to my mind something that's really on the cusp like that could be the exception that proves the rule, so to speak, if used in a context that leaned fairly well toward the ideal.

The example that jumps out right away for me would be the Two Lane Blacktop '55. That's supposed to be '71, and they sure weren't no high falutin' deep pocket fellas.

Now, throw a couple Demon carbs and billet air cleaners on top of it, and you're fallin' out of context. But as long as the rest of the formula jives with the intended period and is in context, I don't see what the problem would be.

Wouldn't mean much except that this board is '69 and earlier. I was a kid working at the local speed shop in '68 and '69, and there were always guys who had to have the latest stuff- anyone remember Holly 3barrel carbs? Probably not, but they were a hot item when introduced. Two years after the tunnel rams became available, they were seen everywhere, but that was past the time period constraints that make this board "traditional". An appropriate two four-barrel manifold would be a cross-ram, or high-rise inline type.
Just my two cents, I'm not the one calling the shots.

I figured when I asked the question that they would be on the very edge of the cutoff. I guess it also depends on on what part of the the country, or what country you were in at the time. Some places would have had the latest race technologies before anyone else. I live in Nova Scotia Canada and while we never had a hot rod scene as big as the southern U.S., we did have one. Gassers, altereds, street roadsters, front engine dragsters etc, but a lot fewer. I've been told by a few guys that lived through that time here in N.S. and neighboring provinces that racers back then had a lot of the same stuff as the U.S., but it usually took 1-2 years for it to catch on. These two pictures are of local cars and were taken in '69-'70, which is right on the edge, so that's why I wanted to ask.

'38 Chevy Gasser


'29 Ford A/SR.

What about the M/T valve covers?

I think everyone pretty much answered it.
