That gives you about a 1.80 gear in OD..That's how it got 28 mpg @70 with the a/c on.

Yeah I can see them with the smaller rear.
But have not seen one with the 4.3L LT-1 but does not mean it was not installed.

My 94 Caprice Wagon has a set of 2.56's and has touched 24mpg best loaded with family. Mostly in the 23.5 range.

The Impala SS originally had 3.08's and get a best of 23.75mpg. But consistently 23.23mpg.

When our Impala B-Body guys added the 6sp.
Some installed 4.10's and reported 25 - 26mpg.

His comment about "the hit" and too violent of a hit is the clue.
With some of the new converters that have a hard STR rate I see the same TOO MUCH HIT. Especially on some lighter cars.

The nice thing on our Plus Sized Cars is that we have real 4-link suspension.
The weakness are the attach points on the Frame.

For some reason when properly stripped they can get fairly light even with BB.

Will what was the lightest weight you got your car?

Dan

How much back-to-back converter testing have you actually done? Back-to-back during track rentals?

My fastest coverters also hit the hardest. My min weight is 3235.

If Charie Plott at ATI told me a pi** ant could pull a freight train, I would start figuring how to hook that little sucker up.

Not done back to back testing but a lot of testing and documenting.
One thing the ECIRS series provided was experience from the other Impala racers and their documentation.
My Car ran BoltOn, basically IHRA Pure Stock.

Started racing ECIRS in 2004 stock every thing, best ET was 15 sec flat.
Began with a modified 2800 stock converter.
Sucked on the Street but got the car in the mid low 14's.

Installed an Edge 3000, went to 3200 then to 3600.
More BoltOns likeTri-Y headers and RT Cats, Tune, 1.6 roller Tip Rockers.
Got a best of 1.70 at 60 ft. and at more than one track.
Best ET 13.27 at 100.14 at Etown 4 years ago (1.727, 5.30, 8.368, 11.02) November 42 degree weather.

Got new Warren Engine and used the Edge 3600.
Best in good Mason Dixon Weather was 13.20 at 101mph

Rebuilt the Warren Engine because of a broken ring land.
Installed YankSS 3800 eventually broke the 3.73, replaced with 4.10.
Before breaking the gears ran a best of 1.68 sec 60 ft

Good 50/55 f degree weather cut a few low 13 and teens at Mason Dixon and Island. Dragway (13.11 best)
Cecil Cold Weather Day last November ran a 12.88 at 103.64
Best of 1.65 sec 60' and 8.15 sec in the 1/8th.

The Yank was an improvement over the Edge as it MPH better.
Edge and Yank compete for the LTx/LSx market.

Pat Gish held our Bolton record at 12.37 at 106mph at 4000#.
He used an Edge and Lock-Up on the Converter at Atco.

Later he installed a Yank. Ran similar ET without the lock up feature.
For some reason very little improvement gained when it was locked up.
But was running back in Ohio at higher altitude tracks.

Side by side the Yank Converter Lock Up Band is much wider than the Edge.

Some of the guys have pulled a heavy trailer with the Yank and zero problems.
It is a rugged Converter.

The Yank is about $800 the Edge about $600.
Pound for Pound the Edge is Better.
For Performance the Yank is better.
Both companies give great service.

Based on my launching data will upgraded to the YankSS4000.

Hope this is useful.

You need to call ATI.

Thanks ED..I like Jim at ATI.
Will have him do my 1969 Impala 350/255 Combo when ready.

However staying with Yank. It is a proven Converter for my car.
Do not think Jim has a competing converter or would have heard about it by now.
The Yank feels like to a stock converter on the street. Until you nail it.
If I need a new 4L60E, ATI is a solution.

The stock 4L60E had more than 300 runs and 140,000 miles.
The next one died after 20,000 miles.
Hurt that transmission road racing at Summit Point at FATT.

Shane Cobb rebuilt the next one and it runs great.
He is no longer building them and have found a couple 4L60E only specialists.

Soon will be looking for a good used aluminum trailer.
Problem is finding a place to store it.

If you haven't "heard of it by now" you need to get out more. LOL
How many fast, race winning, or record setting NHRA Stock or SS
cars do you see with a yank converter? About zero. How many with ATI?
Most of them.

[Rob Petrie E395]

If you are looking for a 4L60E transmission builder that can make one live in a drag racing application. Call Finish Line Transmission in Schaumberg IL (city might be spelled wrong) I cannot tell you how many passes are on mine. Its been in mine for years and has not had one problem what so ever. As far as ATI goes Ed gave me the serial number off of his converter from when he was bracket racing his car. (we had similar combos at the time) Called and ordered one. It makes my Yank and my Precision converters look bad. REALLY BAD! Try one you might like it.

Ed
Are you saying most cars that set records have ati Convertors?
Really?

[Ed Wright]

Mark, more fast automatic S & SS cars use ATI converters. Check how many of the last 20 automatic SS NHRA World Champs used ATI converters. Like 17 or 18?

Sure not yanks. LOL

What brand would you say, Mark?

[james schaechter]

Man this thread started out cool and it took a strange turn into a slushbox forum! LOL! Will take this back to reality please!

Tim Quigley had a cool 66 Biscayne 283 O-P Stick that was a blast to race!

He sold that, but he restoring a street 69 427 4 speed Impala SS.
