I recently purchased a 383 sbc for my ‘40. This new motor has a one piece rear main seal so I have to purchase a new balanced flywheel. I found one but it states that it’s for 10.5” or 11” clutch. I’m using the 10” clutch. Will this flywheel still work with the smaller clutch package. I would also like to replace my pressure plate which is a bork/beck 10”
I get ya, but no one knows the hole location of the flywheel you have(will get) or the PP hole locations.
you could measure the PP bolt circle on your pressure plate, and you could do some research online on new flywheels, and see if it matches. I just picked a random application on rockauto to show you where the info is
I think the new flywheel you are looking at has the mounting holes outside the flat surface the pp mounts to . The smaller 10” pp would need to be redrilled , and that may be impossible the way the flywheel is cast . Ps , these flywheels are lighter than an original gm .
Here is one I am considering for my sbc to ford conversion. If I had to redrill theflywheel 1/4 “ for a 10” it would be difficult due to the way the flywheel is made .
I'm actually looking at a 168 tooth Ram billet flywheel model # 1530. Its drilled already for b/b, long and diaphragm
Not to be negative, But that not going to last , @ least I do not think ? Typical mild 383 450 ish of torque , My Flat Head 32 with 39 trains , I Would have to double clutch 1 in 2 , I was afraid it would break with 100 hp
I can't imagine going to the trouble and expense of doing this kind of work just to drive it easy. Had a older gent with a 500 hp 383 sbc in a s10 pickup, it never seen 3000 rpm or 60 mph, why build it if u ain't gonna drive it? A stock 4 banger could have done everything he needed and did with it at a lot less cost, h***le, maintenance, upkeep etc... No I don't understand or get bragging rights other than stop light to stop light or 1/4 mile.... ....
