Actually that is 2 on the drivers side. Once I get it back on the rack I will set it to 1.

I don't think there is any problem running a 302 block with Weber's and no scoop. It is astonishing how far down it sits compared to the 351. Brent has a pretty tall Edelbrock manifold on it and it sits down there.

What about the body roll? Does the pic seem typical? I ask because I may need to stiffen the bars some.

Even with all you have done I'm surprised by how much weigth you managed to get off the car. Your down in FFR and all billet aluminum Kirkham territory now. Very surprising considering how robust the frame and body are on the ERA. Sorry, I'm abosolutely of no help on your questions.

On your transmision height I think I would measure your U-joint angles before getting too concerned. I had my tailshaft sitting at 3-3/4 inches per Bob/Doug and due to some interference betwwen the shift boot/transmission lever/tunnel they recommended I raise it some more to resolve the issue. They sent a 5/8 inch spacer for the mount but I only used about another 1/4 to 3/8 inch movement to clear things up. With my tunnel in place I can't check my angles right now but ERA didn't seem to believe it would cause any problem.

For an ERA I think so. Bruce's #3170 is tighter but as radical as yours.
Dan, I think Cliff wants the weight as low as possible for Cg.

Weight and placement are at the front of the agenda, but like the suspension geometry, I am limited by commitment (t & $)

I remember now how we got to 3 points. We had the car on 4 points, were checking engine level, and noticed one of the points was not touching. We tried to ratchet and it moved the force to the other three but we could not close the gap. I don't know why I was surprised, it is exactly what should have happened. Once demonstrated we set the steering as the primary critical feature and went to 3 points.

Dan - great point on the joints.

Chas - w/ respect to the joints - shim the pumpkin down - LOL

Dan - an ERA chassis with this weight does make me smile. We are in Shelby territory with a real suspension and another 100 hp.

Not sure we have enough trans, but for now

We still need some water and some more oil for the accusump, but there is some give back in the wheels, drive shaft, & front calipers.
