question for you LS1 guys. I have an LS2/T56 magnum , Mcleod RST twin clutch combo. I am using an LS1 flywheel which is recommended by Mcleod for their clutch. What is the right length M11x1.5 flywheel bolt for this app.? The flexplate bolts from the LS2 are 23 mm (.905")
which gives about .780" of thread into the crank when using the flexplate and .565" of thread into the crank using the flywheel. I want as much grip as I can get! What length are the stock bolts for manual setup? Thanks

Not sure of the length, but I would purchase ARP Flywheel bolts. 27$ http://www.thunderracing.com/catalog...ories&pcid=300

I checked the specs on both flexplate and flywheel bolts by ARP for LS1.....flexplate bolts #244-2901 are.880" under head and flywheel bolts #330-2802 are .800 under head, slightly less than the flexplate bolts......with either bolt set I would have about.340" of unused threads in the crank.........am I just being nit pickey about going the extra 3/8" in length into the crank or is 1/2" enough into the crank with the bolts?????

If you are using an ls1 flywheel the bolts are designed to have the right amount of threads in the crank. Dont re-invent the wheel on this one.
Plus they are only $27. Probably the CHEAPEST arp bolt set ever....

I always try to use quality fasteners such as ARP when building anything.....but being a nit pickey/in to the details kinda guy I always measure everything twice , double check anything I am working on and never assume anything (learned those lessons years ago)..........and the deeper you sink your bolts, the more things tend to stay together..........thanks again

I understand what you're going after but short of knowing someone at ARP who can make a hardened bolt the same pitch a few threads longer if there is room, I dont think you will find a stronger way to fasten the flywheel to the crank.
