Jay
Thanks so much for your hospitality.
Your family is amazing and your set up is to be envied.
My adapter is a beautiful piece. I'm thrilled with it.
Good luck with your tuning. As always, will hang on every word through Drag Week.
I'm quite sure my brother will be in touch.
Thanks again.

Marc, it was my pleasure having you and Ryan up; too bad we didn't have time for more bench racing!  I hope we can get together again sometime - Jay

Jay:

On the crank case vacuum I only see 12" on track. I know it could go higher as it flattens out when it hits the vacuum break set point at the top of 1st gear. At idle it barely registers on the vacuum side of the analog boost/vacuum guage I use to watch it going down the road, at cruise around 5-6". It's connected to the driver's side valve cover. In 2012 Scott and I added an additional GM style MAP sensor which is plumbed to the passenger side valve cover. It reads prettty much in sync with the analog guage and of course we can data log it. Still shows KPa as i never got around to mapping the conversion for the virtual gauge.

The engine seal issue turned out to be way harder than I expected the first time around and your SOHC is way more complicated my 385.

When given a choice I opted for -10 lines form the VC's as I was told they would have lower velocity and would pull less oil out of the motor. The big shock was the amount of water in the one quart Jaz breather can at the end of a long day of driving. I ended up with two as just one over flowed on the first ten hour day with a lot of humidity. Now I drain them every day at DW.

Maybe here?

No joy with those guys either.  Most of these outfits seem like they advertise the throttle bodies as "in stock", but they don't actually stock them; they get the order and then direct ship from Accufab.  I've called a half dozen places so far and its always the same story.

Accufab says they will have the throttle bodies next Monday, so hopefully I can get them by the end of next week.

Jay, I went back and browsed the 2011 thread on the build of the Shelby clone and was just wondering how the paint job is holding up. And have you made any changes to the car at all? Specifically the rear suspension. I thought I read that you didn't think that you had enough adjustability to get the IC where you wanted it. Good Luck this year, glad to see that your gonna get some track time before hand.

The paint on the fiberglass parts has developed a couple of minor chips, but otherwise it looks OK.  The big issue is the color, which just didn't turn out like it should.  The low solids Omni paint I used gets the blame for that.

When I was going to Drag Week in 2012 (never made it that year) I had lengthened the lower mounts for the lower 4-link bars, so now I think I'm probably OK with the geometry.  Time at the track will tell...

I remembered that you used Omni, thats why I was asking. I've heard a lot of stories about it not adhering etc etc. Sounds like you made out good (other than the color) for a car painted at home. I think it looks great. And I can't wait to see how this year goes with 2 months worth of testing instead of a last minute thrash! Must feel pretty good. This car's gonna need a chute and wheelie bars!
