I guess this could go in "Everything Goes", but this forum could use some more traffic. Anyway, I got the new motor swapped in and am in the process of building the exhaust system. Still several details to iron out, but I'm ready to get this thing running - the weather is going to be decent in about another month - time to race. Clay


This is the "X" pipe kit available from Summit or Jegs. I built my last one from mandrel bends and I'll absolutely say this is worth every penny.

This is going to be a set of tailpipes.

Mock up.

Making tailpipes.

Do all stock Novas have unibodies?
Impressive work on your car.

The 1962-'67 Chevy II/Nova didn't have any frame at all being a true uni-body (Monocoque) construction. the 1968-'74 used the same front stub sub frame as GM put under the 1967-'69 Camaro, with the 1975-'79 Nova using the slightly wider but better handling second generation Camaro stub frame. So the last half of Nova production had half a frame, while the first half of them had none at all.

Clay is this going to have the same blow through set up? And is this new combo going to require a lisenced driver and a certed cage?

It will have the same Procharger / blowthrough setup for a while. Right now I'm doing two things. First, I'm going to put a few N/A miles on it to break it in a little. Second, that Quick Fuel carb on it now is a friends that had developed a little hickup right off idle. It had been running great and we didn't find anything obvious when we took it apart so I'm going to look at it with the wideband and see what's happening. The old setup ran a 10.05 in the 1/4, so ideally it would require a cage cert. and a license. I don't run at any tracks that require either, so they probalby won't happen. First I want to run it with the same supercharger drive ratio and try to get an idea of what sort of improvement the heads delivered. Then I'll step up the maximum drive ratio and see what happens. I think wheels and tires will need to be my next move, but we'll see. Clay

They're 3" offset in / out Dynomax Race Magnums. I think they are actually called welded ovals now. I had the same muffler on the car before in a 2 1/2" version. They are probably going to be louder for now, but in the future I plan to install a pair of "rotary mufflers" in front of 'em Wink . Clay
