B/PS lt1 formula

While the spline count is the same, at 30, there are differences in the turbine shaft. The majority of the 700-R4 transmissions used a "298 mm" torque converter. The turbine shaft has a stub and an o-ring on the end close to the engine, the splines are closer to the transmission end. Most of the car transmissions used that combination, even the early LS engines. The trucks with LS engines got a "300 mm" converter. The turbine shaft has the splines closer to the engine end and a journal and o-ring between the spline end and transmission. The basic converter to flexplate spacing is the same between the 700-R4 (4L60-e) and the 350/400 THM transmissions. The later 4L60-e with the 300 mm converter is different and would require a different flexplate , and a spacer for the crankshaft to converter pilot.

I use to remember getting those for the LT1s Dan at my local plumbing supply store. Always got a funny look when you told them what it was for.

The Last time I replaced the garbage disposal.
It came with a new Drain.
Noticed the Drain was 3 inches. Remembered the B-body MAF was 3 inches.
Used a coupling from the original First and Second base intake set up.
Fit like it was designed that way.

Do not know if it adds HP. But leans in that direction.
At the track it gets a lot of big smiles.

SWEET! I have one of those in my kitchen right now! Wonder if momma will miss it?? LOL! How much was that worth Dan? As quirky as these things seem I wouldn't be surprised if it picked you up a dime.

Dan, I'm not trying to toss any "garbage" your way, but is that legal in Pure Stock? In the past traditional stockers have had "non-OEM style" air filter bases questioned by Tech (at NHRA events at least), and I would think Pure Stocker rules would be even more restrictive. Don't shoot the messenger; just trying to avoid a spike in the sale of garbage disposal parts followed by a bunch of Pure Stockers being told to take them off.

YES it is legal.
Been to many IHRA ProAM and Jam events..
Gone through inspection...NP. The Tech guys just smile.
When I go home replace it with a Cone Filter.

Want one
