Never had an original top loader, used to have a Muncie but changed to a TKO600 some time ago which I guess is kind of top loader family. Its fine, have hardly driven the new engine yet, certainly not in anger, but the box is rated to handle 600ft-lb so I would be a bit disappointed if it was a problem! Bought it brand new and I've never had the 2-3 shift problems that a lot of people complain about.oldn64 wrote:I had a very brief look at the photos and wonder how you find the top loader behind the new stroker?
It wasn't supposed to be heavier, its advertised as light weight. According to Yella Terra its somewhere between 10.8 and 11.3 kg, and their standard weight one is 13kg. According to my scales its a little over 11kg, but I have two different factory flywheels which are around the same if not slightly lighter (although at least one has had a skim in the past). I can't see how a factory flywheel would be 13kg though, so it must be based on a Chevy one (the 153 tooth Chevy flywheel is almost identical to V8 Holden, just has one bolt hole in a slightly different spot). The ultra light weight one is something like 9kg I think which might be a bit much, my main concern was adding a little safety factor - I've pulled out cast iron flywheels with scary stress cracks in the past.oldn64 wrote:What was the reason behind the heavier flywheel? I would have presumed you would have wanted to go lighter than stock?
I had an expensive clutch that was organic on the flywheel side and metal on the clutch plate side, it was very worn out after only a couple of years moderate use - at which time the supplier tells me that's normal! So now just a heavy duty organic clutch (10.5"), didn't replace that as its not very old. I have a Tilton hydraulic thrust bearing for the release, pricey but you never regret it once done:oldn64 wrote:What clutch did you end up using? Are you using a hydrolic clutch or the original rat trap crap?
Possibly, MyAutomotive are selling Yella Terra stuff now. Be warned though, they're yet another supplier that pretends to stock items that are ordered on demand. I was almost drawn in by the dash 3 heads they had advertised for $3K but had to confirm since its way too expensive for one but suspiciously cheap for a pair - after my enquiry the price magically went up to $5.5K...immortality wrote:Is that steel flywheel the same item I see advertised on TM?
