Get that engine lit off!

We have to pull the drive train back out to finish some odds and ends, but dry fit looks pretty good. Your day is coming and it will be grand - I keep spinning it.

FWIW , I sent an e mail to Avon several months ago about the CRZZ6 tires on the track . The Technical Director recommended 1.5 to 2 degrees negative on the front and 1 to 1.5 degrees negative on the rear as a starting point and then use tire temps starting from the inside to outside to set final camber .
Looks like Roger Krause talked to the same guy I did ... and Roger has a lot of actual track experience with Cobra replicas on these tires .
I have 2 degrees negative on the front and will probably reduce that very shortly as insude temps are too high .

Interesting - one of the first questions was - which Replica ?

Don`t know . He just said during our conversation that he supplies the Avons and the Goodyear Blue Streaks to a lot of the West Coast guys . And here I`m dating myself as I used to run the Blue Streaks way back in the day .
Yes , one is a radial and one is a bias ply . I think he told me that the Goodyears were slightly faster when warmed up on the track and gave more warning before breaking away , but you can drive the Avons on the street also and be as fast or almost as fast . However , as you know , how fast the car goes on one set of tires over another is determined a lot by the suspension setup and the driver .


P.S. I run 15" wheels .

The motor mounts are not working out as well as we would like. With the engine sitting level in both directions the output shaft on the transmission sits 3/4" too high. We re-worked the trans mount and bracket and it is sitting 1/4" too high with respect to ERA's 3.5" dimension to the top of the "X". We would go ahead and lower it to spec, but we checked the engine for level and we now have slope and lowering it anymore will just amplify the problem which is not the best for the Webers.

Also, the mount does not have full surface contact to the frame horn. We have decided to go to solid mounts.

Question 1 - How critical is the 3.5" tail shaft dimension?

Question 2 - Anyone ever play around with lowering the engine and trans?

We are considering going to electro fuel pump. I spent some time searching and it seems several have run 7lb pumps with no return?

Question 3 - Can you guy's shine some light on this?

Got my valve covers in from Nick - perfect.

ok - so lowering is out- headers are pretty tight.
