I really want that 11 second time slip this weekend but, given the time I have to work with, I understand that I may not get everything ironed out like I hope and that there will probably be a lot more tuning to do in the future. If I ran some 12 teens or lower, I'll be happy. Heck, I could be way off with how I think it's running too. I took it out the night before I took it to the track last year and it felt great but, ran over 2 tenths slower than the year before.

Funny you mention the jet and what I think is too much pump nozzle. I actually checked for vacuum leaks with the butane torch after the first few times I had the car out as I was surprised it needed as much fuel as I'm throwing at it. I thought that there may be another issue. Ultimately, I keep telling myself that if I add more fuel and it runs better, then, it needed more fuel and who cares what the actual jet sizes are.

My ultimate goal is to run some 11.50's to 11.80's on a stickier radial tire like I have on it (American Racer right now or the Mickey Thompson Sportsman Pros I had before) and whatever I run on the bias ply whenever I decide to go to that tire is what it runs.

That 511 ended up running 11.50's @118 in FAST trim in good air.
With some M&H 28x7 retro style slicks it went 11-teens.

The stock intake and ex manifolds really put the hurtin on the horsepower with that combo.

I spoke with Harry a few times at the FAST events at Trails. His Bee is as close to my car and what I want my car to be as any in the class which is why I approached him.

The exhaust manifolds hurt my car by a little over two tenths. I know the intake is a killer too.

Right now, the intake, carb, fuel line, electric fan and rear tires and wheels are all that is left that are not FAST approved.

In all honesty, it will probably be years before I run in the class but, you never know, I didn't plan on doing heads this year either and just got a wild hair.

And the bad news came down about an hour ago; Trails cancelled their last event for the year so; it looks like I'll have to wait until next season.

I'm not happy but, it will give me some time to get this straightened out more. I have a wide band I bought a few months ago that I've not hooked up yet and I may go back to the chassis dyno too.

Still racing at Edgewater. Come on down!

Plus you’ll post better times and mph.

Hi Moparts,

Any 906 news, since the dreaded lockdown?

I'm building a 511ci motor with iron heads but not sure which ones to go for?
Got some very trick 906's by Rob Loring UK, some by Koffel and a set by Jeff Hauser Uk too.

But I also had a set of 452's by Koffel which I sold and now regretting!
They were very light as the machine work was awesome.
Milled a 100 thousanths and the quench area re-machined to approx 30 thousanths depth.

So as my ride is a 71 GTX for UK Superstock, I may go with some first gen 'flat-port' 902's...
Just because I have a spare set of them.

Lost most of the pics of the 'ICE heads' made by Rob Loring.
Raised port by approx 1/2'' and fitted a 5/8'' spacer onto each head.
Ports still 906 sized with air deflectors in the port floor, with Team 'G' domi intake

High compression 452ci motor in my Street Dart ran 10.44. (Dart in avatar)
