I tried to get away with using my 11" flywheel and clutch setup on my 351/408 windsor and TREMEC install, but without buying a spacer to use my old bell housing and reconfiguring the hydraulic clutch actuation for the slave cylinder I am not gonna be able to use it, I figure I will need to go down in size on the flywheel and clutch setup to get it done, and this will be the least expensive way, I have a few questions though, 1. I know I need a 28 Oz. flywheel, but will I have to have it rebalanced with the crank and my existing harmonic dampner, both (11" flywheel/harmonic dampner) were balanced with the crank or can I just get a 28 Oz. and bolt it on?.... 2. which flywheel will work a 10.5" or 10" and which one can use a diaphragm style pressure plate? Thanks
im pretty sure the bellhousing dictates the size of flywheel needed. thats because the starter will be located by the bellhousing. if your motor was ballanced by the machine shop with that flywheel you will want to take the old fly wheel and new flywheel to the machine shop and have them match balance the new one to the old one. ive had this done many times. my local clutch shop (south land clutch) has pressure plates that work with any flywheel and bell housing combination. im sure a local cluch builder should have the same access. i would recomend getting a blowproof bellhousing. youve built a powerfull motor and have the potential for a flywheel or cluch explosion and cutting off your feet is never a good thing. the quick time bell housings come with both starter postions for the different flywheel tooth counts and it comes with both clutch fork mounting locations for push or pull type clutch forks. basicly it should have every thing you need to make what you have work and keep you safe.
Thanks Bryant, I have a Lakewood SFI scattershield now, it has places to actually mount different starters, I feel as if I go that route I will need the spacer as my TREMEC has the longer shaft, and additionally I am not sure the Hydraulic slave I have now would work with it, there is very limited number of machine shops here and I know of none that will do work on a flywheel other than balancing it with a crank like mine was, or resurfacing it, they cite safety concerns is why they won't/can't do it, I spoke with my engine machine shop just now and told him my concerns and problem, he said I should be able to find a quality 28 Oz flywheel and bolt it on with no adverse effects (as long as I stay away from the offshore cheapies) he didn't say which one to look for a 10" or a 10.5" or which I could use a diaphragm type pressure plate with. Oh almost forgot, I have some heavy gauge sheet metal and a friend who would weld it in for protection, just looking for the least expense, I have the original TREMEC bellhousing.
Okay, after doing a bit of research on this I have figured it out I hope! I can use my Lakewood Scattershield and my hydraulic clutch should work, I will need the spacer/adapter plate to use the scattershield I now have because my input shaft on the TREMEC is the longer 5/8, this should be the least expensive way to go at under $200.00 for the adapter plate, I can keep my 11" flywheel (that is balanced with my crank) and my 11" clutch setup that I hope provides me with more clamping force on the clutch AND addresses the safety concerns that Bryant pointed out earlier in this thread.
