Right. The monster clutch I have includes an aluminum flywheel which is also neutrally balanced, so something has to change.The flywheel is balanced to the engine the clutch assembly should be neutral balanced I've never come across an asymmetrically balanced pressure plate even on Dual Mass fly wheels.
The difference between the na and supercharged flywheel balance specs is 2 oz inches on early supercharged and na engines the later supercharged seem to be only one ounce inch off. I have rebalanced to the larger offset of the supercharged engine for my mezeers but a factory one I've never bothered with.
Naturally aspirated is 20 oz while early supercharged went as high as 22 but somewhere around $2,000 and later it only measured out at 21 for supercharged. L32 and l26 balance the same as their forefathers
I didn't realize that the L67 pistons were that much better.Regarding the L67 vs L36 bottom end. For sure the pistons are going to be more resistant to knock chips on the L67 and the rods are so much beefier.
I know some people have pushed the L36 rods pretty far but I've heard a lot of people have broken them due to too much power. Stock cam turbo cars do make gobs of torque though and that's what would break a rod so that could be the difference between the ones that lasted and the ones that didn't.
I would just send it on the flywheel with L36 balancing either way. Pretty sure the vibration I was talking about with mine is probably due to my engine having low compression on a hole.
It may be thicker but I feel like having a dish in it is going to negate the strength factor when you compare it to a flat top. James would know but that's just my miseducated guessWhat I understand is that having more area above the ringland gives it more strength to resist a ring that is trying to chip off an area of the piston. It seems like it would also keep the piston ring a little further away from the heat too.
I'm definitely not the expert though, this is Turbocharged400sbc territory haha
If you don't do it nobody else is going toI keep looking at the aftermarket 3.8 crankshafts and I seriously keep wanting to just make a rear block cover that uses the old style seal
