flywheel
« on: January 18, 2006, 10:09:00 PM »
Is the fly wheel the same for a 700r4 as the turbo 400.  i'm doing a swap right now and i stuck the r4 up there and there is about a 1/4 inch gap between the torque convertor and the flywheel.  

'86 C10 Silverado 350 with 700r4 and 2500 stall
Dropped 2" in front and 2" in rear but soon to b 4" in rear
18x10 wheels with 295/45 18 tires

Technically the flywheel matches the engine/crankshaft.  The torque converter matches the flywheel and the transmission matches the block.  Is it the factory flywheel?  Will the TH400 bolt up properly?  Can the converter not be pushed forward to meet the flywheel?

What size flywheel do you have for the 400? There are two sizes. 153 and 168 i think its 168 but you can tell by how the starter mounts if the tranny is still in the truck. The 400 has the big flywheel and the 700 is the small one but it depends on the bolt pattern on the torque convertor.

I have never seen shims between the converter and the flywheel out of all the Chevy trucks I have owned.

Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs

Neither have I.  Why did it have to be shimmed, the converter should pull forward to meet the flywheel.
