I'm pretty methodical on my break ins all in good time!

You got more restraint than i do. Usually within first couple miles i find out how she's running. If something going to break it's going to break imo.

Yep me too! "I feel the need for speed"

I must be getting old or something! I guess it comes down to having the street tune perfect first, plus double checking the car over again.

Skip, thanks again for your help with Dutchman axles. The upgraded rearend feels like I never touched it.

On the dyno our engines get 5min of warm and checks and then let her rip. On the track (our race cars) get 1 easy pass (half throttle or so) then let her rip.

I let er rip tonite...feels really good..no hiccups etc.It really feels like a lot more power..punched it in first gear doing about 5mph and instant smoke thru all the gears until I let off.Down the road a bit I stopped brake revved to about 1500 rpm nd let er loose same thing even with warm tires.

I have the in gear idle at 800 rpm now it still pulls good vacuum..still have some minor tweaking to do but I'm pretty happy.

The car really lulls one into thinking it doesn't have has much power as it actually does..but boy does it wake up when you let it breathe.

10.95 to 10.55, my humble prediction.

I hope he realizes that large of gain, but I am going with 2/10. The previous motor was certainly no slouch!

Good luck when you get on the track again!

There is a big difference between the bottom ends, old shortblock had a bit of blowby, heavy TRW's in the hole .020.The new shortblock is zero decked, balanced, light CP pistons, meticulous attention to detail and assembly.

First time out I will take any gain, I would be happy getting in the 10.8's with a 10.6 as a long term goal.

Weather permitting we are going Friday night and Saturday afternoon.

Like many I hope it does well. After the track results consider a new thread with results and so the new people won't have to wade thru all the posts how about detailing all the changes made, including specs.
Just my .02

I'm just hoping for some improvement of any kind. I'm remembering the "for sure" improvements that were coming with the RPM experiment...Your new improvements all point to better ET's especially considering all the insight from others..

I'm not a racer, but am concerned about traction, most of all...

Many thought the rpm intake was a logical choice with the gearing and weight.It just couldn't compete with the torker 2 and the one inch spacer. At the time neither intake was "ported" just a simple gasket match.

Glad the Dutchman axles were a go for you. They seem like real helpful folks and the only ones that would address a longer brake pilot for the discs. My 81 has them on the 3.08s also that will get a SP HR cam 455 this year so I've been watching this deal close.
