When you spin the tires badly at the starting line it will raise the mph for some reason. We all know that he has a great running car but mph on this run may be misleading.

I'm fascinated with Weedburner's setup, I'd like to see photos or a diagram.

Yeah, that's stout MPH, suppose like PBR says wheel speed may be augmenting that, but it still seems to indicate good power to me, enough that you'll be shopping for a rollbar soon.

If you ever need a hand @ Woodburn, a buddy of mine (Brett) runs there, usually a brown '66 Chevelle wagon. I'll volunteer him!
Just tell him you know Steve with the Hamburger car.
And keep up the good work on that other thing.

The new version for hydraulic release systems is called the "HitMaster". Installs between the clutch master and slave or hyd t-brg, here's a plumbing schematic...

What about guys who don't run hydraulic clutches???

I didn’t spin on the 120 pass. I had to just ease off the line and let off when I shifted.

The passes where I did spin were killing my mph. A drag radial is a lot different than a bias if you spin. When they spin they do it badly. I had to let way off to gain traction again.

Since things are a little slow around here I thought I’d share my build and my first outing experience.
First off the car is a 1974 ‘cuda 4 speed with 3.55 gears. It’s all stock except motor, wheels, tires, and scatterhshield.
When I bought the car 10 months ago it had a 360, probably built in the early 80s late 70s with forged pistons, w2 heads, strip dominator.
I decided to stay busy to help my sobriety (8 months now) and year the engine down and freshen it up. Well then I decided it’s a great time to add a 4” stroker kit. Unfortunately I got the scat cast crank kit since I was just building a mild pump gas w2 motor. Well then I find it’s impossible to find valves and didn’t want to invest in new guides and ordered custom valves.
I then ordered a custom solid flat tappet from Duane Porter that’s 251@050 and .556 lift on 108.
I srtarted getting impatient knowing my car may be down all summer waiting, so I contacted my buddy Del who’s a member here and asked if he had any heads he’d sell to get me going. Well he did. So now I have a 360-1 top end with intake and 1.6 rockers and I couldn’t be happier. They are bowl ported by Duane with a little short side work is all and flow 312@650 and 297@550 which is all I’m using. I put it together within a week at this point and ran it Saturday at Woodburn. The build is now as follows.
11.5 compression
251@050 and .558 at the valve after lash ( yes the offset rocker robs that much lift I found).
Indy intake
1050/4150
2” headman headers
4speed
3.55
275 Hoosier radial ( did not work well)
So with only 3 passes I managed a terrible nice easy pass since I couldn’t get traction.
2.163 60’
12.08@120.23
I am happy with the power it’s making my first time out with no jetting or timing changes and with some bias and gears and timing it’ll only get better. Yes I plan to upgrade the crankshaft this winter lol.

The cam card should say .556 lift...... which would be with a 1.5RR.

He’s saying even with his offset 1.6’s(combined with the screwed up lifter to pushrod angle)it’s still only .558 at the valve.

At least that’s how I took it.

There’s a few e bodies with sticks leaving soft and running good times on this vid:
