Heavier clutch spring (minarelli build)

[mountain80]

This is 500# it's a double for roller cams 600# would wash the lobes out of a 340 and not cheap... But if they fit I'm glad... But still waiting on RDM to pull something off... The LS motor valve spring is 400# little smaller.... ?? I've had 273 -360 Mopar in a bunch of stuff 66-82

RDM has had supply issues due to outside issues, springs for example
I talked to Ryan and the spring manufacture has not given him an ETA. Just another facet of global supply shortage I am afraid...

Someone in Pittsburgh has a 55 gallon drum of valve springs... That's just too genius to work...

If a guy can find something easier to obtain why not right? I am waiting as I have time to finish other aspects of my minarelli build, they will kill a stock china girl clutch, build it strong and build it once.

I'm not building a 10 horse monster and need the full blown deal... I'm fat and looking for a reliable clutch ... I'm getting some ideas on a bunch of junk I can use

I also talked to Ryan Manu.. and he said I can use the stock ones.... What about a transmission shop for big trucks some of those look close from my fading memory lol

Mossy, one thing I remember is a stock clutch disc suffers from flex, warping, and unlike an aftermarket plate does not fully cover surface of clutch pads. I had a souped up chinagirl before and surface ground the plate. Worked for quite awhile than started warping as I rode it hard. Someone once posted that they pit a second clutch plate on top to increase rigidity. Maybe with heavier spring it's worth an inexpensive try?

Yes... I like the rdm pressure plate... Doubling up the stock ones... I got 10 from the same place to try once I get that far.... The RDM is a bit of a thinker he uses shims behind the bearings 2 different ones a wide 202 bearing im not sure what it is a longer shaft washers on the pivot shaft housing and the sprocket sets out 1/8" or so than stock... What he was saying longer bucking bar also... I'm probably forgetting a few things also... It's not plug and play setup he has...

If you are talking the stage 3 or 4 I know what you are talking about. I have a stage 2 waiting for a spring.

I'm order # 1999.…. Im going to use a 5/16 g25 hardened ball bearing in the shaft and the 1/8" g25 ones in the pressed collar ... Amazon has them

Clutch bearings... Pgm...and the strongest single speed chain by wiperman... Is what I have so far...

That's total BS, I went to an engine builders shop used his spring tester and found the 600 lb spring I wanted and he told me it was from a 340 Dodge (not stock) the stock spring was 390 lbs.
Most three spring setups are just over 600 lbs!
