A couple of things happened today.........The original drivetrain is now gone and on it's way to be installed in another Chevelle and to live another day................And.....After looking at the 6L90E trans and measuring everything.....I'm just not comfortable that the trans pan will be high enough for me to drive the car comfortably worrying about that pan hitting something as the car will be a couple of inches lower than stock with the Ridetech Coil-over suspension.....So.......I'm going to buy a built 4l60 trans that will fit without the trans tunnel surgery and pan issues......I need to resolve some issues but John at Speartech has said there wouldn't be any communication issues with the computers .....so....looks like that's the way I'm going to go......(That's today's plan anyway.....LOL)



Got some more boxes today also..........Christmas in September..........Dakota Digital VHX Gauges........and a "Real" set of brakes.......

Now I'm really confused.......It looks like you are close to the level of the bottom of the oil pan with that Caddy pan.........

Made some progress today......First.........I ordered a built 4L70E trans to replace the 6L90E........John from Speartech is going to make the harness mod's to suit the different trans and said it's actually much easier now......... So.......I took the trans off the back of the engine and brought the engine home to meet the car for the first time......LOL.....The new trans will be delivered in a couple of weeks so while waiting I'll get the new suspension on the car......then continue with the engine install.......If anyone needs a 6L90E with 2000 miles , let me know...........Here are some pic's from today.....

Ken,

Should be alright....I wouldn't be surprised if you needed more. I have 550s on the front now and after talking with Ridetech, I would easily go with 700. With the extra weight of the supercharger, you might need more too. But springs are inexpensive and easy to change...

What are you going to do about the lack of a slip yoke for the trans? Or does it have one

He is going to use a 4L70...presumably it will have a conventional slip yoke.

Can you please tell me which Kwik bracket you ordered, truck, ls1 or Vette? I am putting an LSA blower on an lq4. Thanks!

Got the front spindle hubs installed......when I opened the box with the rotors I noticed they weren't cad plated.......So I sent them out for plating to keep that rust from showing up later.......I should have them back for installation tomorrow......I also ordered a Posi unit so I decided to wait for that to show up before getting involved in the rear end......so....I jumped into the inside and finished getting all the original A/C removed along with the dash and wiring......I also sent the stock AM radio out for conversion to AM/FM Satelite..............Started mounting the Vintage Air system.......Having Fun!!!

OH WHAT FUN ! I would add some silicone around those defrost ducts against the dash to prevent vibrations, and i used reducers off the evaporator ( melted them to fit ) and used the smaller hose for all of the ducting .It couldnt get all of the larger hoses to fit under the dash . JOHN
