Well, its been a long time and coming, but I have been wrenching my butt off on everything and I mean, I am sore, tired and just plum wore out. This car, the 70 Cuda with the Big Hemi was never really meant to be anything but a show poodle, and over the years, I have finally put all the right parts on it.....Almost.

Off the trailer, thru the mufflers, on "street" DOT tires....6.47 first pass untouched!

Incrementals were 1.391 60ft, 4.12 at 330ft and 6.47 at 102.99mph in the 1/8th...Front end bouncing as it kept try to lift the front off the ground as it unloaded the rears.

2nd pass, a 6.48 with me lifting completely out of the throttle twice as traction is now a big issue....Broke the tires loose in 1st, 2nd, and then the shift into 3rd....

Incrementals were 1.40 60ft, 4.12 at 330ft and 6.48 at 104.66mph at the 1/8th...

Made some suspension adjustments, lowered tire pressure some more, dialed a 6.45 thinking if it hooks, I am going to have to hit the brakes....

Final pass 1.392 60ft, 4.08 at 330ft and 6.37 at 107.15mph! Didn't lift cause I bulbed it....

Now realize my mufflers weight a ton and shrink down from 3.5" header flange to 3" and probably kill a bunch of horse power, and the Thumper carb worked awesome. I can't say enough of how good this carb is out of the box and how close it is running to optimal already.

I am going to lean it down a tad for this Sunday's outing which will put it right back to where it was jetted when it showed up....Plugs showed color was a tad rich as the AFR gauge said. Dominic and I have talked about settings and different conditions the AFR has read, and every step of the way, its gotten better as we discussed what to do and dialed it in one change at a time. Went from overly lean cruising to almost a tad rich, but very drivable, and should be right on this Sunday I think. You always want just a little rich on a new engine, and I didn't even have 100 street miles on this combo yet.

Also, we never re-set the valve lash while hot which is loose yet, and the timing is not optimal yet either...

The only thing that did not survive was the straps on the diaper we are required to run...Those melted off, and the Gopro is giving me fits...I will post vids if I ever get this stuff all off the card and uploaded.
