I'm sure this will be a simple one for all you gurus...I have a 1964 sbc 283 that I want to mate to a 1980 Borg Warner Super T10 4 speed trans. Does it matter if I use a 283 flywheel/starter (153 teeth), or the 1980 flywheel/starter combo (168 tooth) that I got with the transmission...or something else entirely? Whichever combo, I would have the crank balanced with the flywheel that I end up using. The block is drilled for straight across as well as the angled starter bolts. Again, thanks in advance.
The Super T-10 trans has a fairly large and fine splined input shaft; I don't know if there is a "small" disc (10.4") with that spline. I'd use the largest flywheel/clutch ***embly (168 tooth flywheel and the bigger clutch) in order to b e sure the disc will work. I just happen to have a rebuilt diaphragm clutch and disc for cheap if you get down to the U.S.A. here in Everett, Wa. There you go; my look at things. I am Butch/56sedandelivery.
1980 was internal balanced, the external started in 1986, eh? And they used a flywheel that won't bolt to the 283 crank. The 1980 400 and 454 were externally balanced, but as far as I know were never offered in a car in 1980, so they would not be used with that transmission.
Never gave auto vs stick a thought before. Were there ever external balanced engines to manual trans vehicles ever?
1986 started the one piece rear main seal so a different flex plate or fly wheel was used is the difference but not externally balanced.. The end of the crank was different from those years. Use the matching flywheel and clutch that came with trans on that 283. here is a quick shot from the "BIBLE" (Hollander interchange book) showing it will fit that 283 This was for a 11 inch clutch interchange. I could not get ALL the different cars/trucks it fit in the pic as one can see on the next page it continued. I LOVE my OLD books
The later flywheel for the one piece rear main seal engines, is indeed externally balanced. The 4.3, 305, and 350 use the weighted flywheel.
Now that the technical years and apps have been briefly covered. How often has a said engine been not what it should be? That said let me reword my first post with a photo. Just be sure the flywheel in question doesn't look like this and all will be OK.
Yes. GM made a 400 SBC stick shift flywheel, used in some 70's C /10 type trucks. 70's 454s also .Plenty of them. I think that's what you're asking.
My choice would be based on light car, 153 tooth, heavy car 168 tooth. Contact the clutch manufacturers to see if they make a Super T10 disc to fit the 153 flywheel. You will probably need the 168 bell housing to use the bigger fly wheel. After that let your budget be your guide.
There is no such animal as a 283 flywheel, The same flywheel will fit 265.s 230&250 sixes ,327, 307 and 350,s and 366 -396 -402 and 427 engines. It will work on any mill it bolts to as long as the mill is internally balanced and the flywheel is neutral balance. Ive never seen a factory small block 400 with a stick trans. They must be few & far between. Ive junked dozens of those 73 and later pickups. and very few have std trans.
We did have one pickup that had a small block 400 and a stick trans. the engine leaked oil and vibrated. tore the bottom end down and the mains where shot. It had a flywheel that was balanced. I still have that flywheel. I always suspected it was a 454 flywheel?. We paid $500 for the truck nice looking red short bed with chrome spoke wheels. sold the body for $1000 sold the crank and rods to a guy wanting to build a 383, for a $100. Sold for a $100 the Saginaw 3 speed to a stock car racer. still have the 400 block, I use spacer bearings and put 350 cranks in them.
On a stick shift netural balance engine. I prefer to use a 168 tooth flywheel from a chevy truck that will accept the 11 inch clutch and the 3bolt starter that bolts to the bellhousing. on a automatic is still prefer the 168 tooth flywheel (flexplate) and a block mounted starter with the holes directly across from each other. Preferably with a cast iron nose.
I've swapped flywheels back and forth between a 396, 327 and 283. These are all internally balanced engines, nothing later than a '74. It is also my preference to use the 11" clutch with a 168T flywheel, preferably from a truck with the starter-mounted bellhousing.
400" small block in a 4 speed truck. External balance stick. LOL If you want to stay stock use the 283 flywheel you can get a clutch plate to fit the borg warner. If you want to be all billy bad *** get an aftermarket flywheel and an 11" clutch. We ran an 11" clutch on a '63 283 powered Bisquit I look back on it and the Zoom Clutch was overkill. The money could have been better spent elsewhere. LOL
You can buy A 26 spline 10 1/2 super T10 clutch kit for the 153 tooth flywheel . I have bought them at auto zone before and summit racing has them.
I'm running an 11" Zoom diaphragm clutch in my car, think the pressure is like #1750. So with the hydraulic clutch, no sweat in traffic.
