What John and I got done Sunday.  The bulkhead will be in the front hoop you see in the upper part of the image.  The rear hoop will not be round as we plan on running the exhaust right next to the skin unless the car tells us different.  The next step will be to plumb several things on the mock up motor so the car will tell us where to run the frame rails.  We know where several will be, but not all. 

Pork Pie is to advise us of his thoughts on the configuration of the frame and body back of the trans mount and under the rear axle.

Looking good!

Tight fit though, huh?

Last Sunday Joey, John and I dugout one of my old truck blocks and mocked up the drive train to see if it would be possible to get a tall deck in--just barely---maybe someday we will win the bigger bullet lottery!!

Today we notched the lower frame tubes 1.75 .134 dom and tacked them to spacers and the the build jig.  Put the mocked up eng., trans, rear axel between them and nailed down the eng placement.  We have not ben able to get the 2" DOM frame hoops rolled to a 30" diameter---this car is going to be LONG; between 26' to 30' OL, wb around 222"

Not so long.  I ended up with 250 inches.

One approach that you might consider is the way the guys with the Contrivance Special modified roadster guys do, a short individual header for each cylinder with some leading and trailing aero devices.

Got any pics of what you're talking about Rex?

Gotzy,
I checked my Bonneville pics and do not have one of the Contrivance modified roadster, maybe some one else has one that shows the headers. Just imagine fairly short stacks, 12-15 inches long and pretty much straight out from the side of the block with a slight, maybe 15 degree bend toward the back at the end of the pipe. Then they added sheet metal between each pipe and added a tapered tail on the last tube. Just another of the many innovative aero things that are on the car. It does not follow the prevailing thinking in the modified roadster class of being low, flat bottomed, pointy nose and straight sides. Again they hold all of the unblown gas records from E through AA so they are doing something right.

Rex
Rex

Not much matters and the rest doesn't matter at all.

I know you and I don't see eye to eye on all things aero Rex but ......on a roadster it may not be that significant but the pipes themselves aren't the issue, it's the exhaust flow that is detrimental to the airflow down the sides of the vehicle, if it is at the very rear it can be a positive influence.....zoomies are a hell of a lot easier, but if we were after the easy route we wouldn't be doing this anyways.

Send that exhaust out the tail.

Here are a few shots of "Contrivance". Record holder in 6 (maybe more?) AA, A, B, C, D, & E gas modified roadster class.
