I have done reading on here and other boards but havent found a answer. I am putting a t5 out of a '93 s-10 behind my chevy 153 inline 4 What I know: I have a 1.00 14 spling input shaft A fly wheel from early chevy V-8's and 153 teeth will work on the 153 What I am having a hard time with: If I get a clutch for the s-10 or the 153 the pressue plate is to small to bolt to the v8 fly wheel The s-10 flywheel crank bolt pattern is not the same as the 153 The stock 153 fly wheel is crap, HEAVY, and I can't find one. I would much rather go with a modern one anyhow. Any suggestions? has anyone done this swap and what did you use?
Redrill the V8 'wheel to fit the smaller clutch, or use the bigger pressure plate with the S10 disc. As long as the inside diameter of the plate is about the same as the inside of the disc, it will work. The banger sure isn't gonna tear it up! There is a clutch that works, it's for a 4.3 Astro van, 1985-86 I think. Hard to find, but a good parts guy can get one. Don't go to GM, they no longer stock them. Napa, Bumper to Bumper, etc., should be able to find a rebuilt one for you. That's the only V6/V8-to-small shaft T5-clutch GM ever used.
On a 4.3, you have to cut the end of the T5 input shaft off a bit, it bottoms in the crank hole. The banger might be different, but check it to be sure.
All the pressure plate I find that work with the v/8 fly wheel are around 10 inch and up, all the clutched I am finding for that shaft are 9 1/8th does'nt mate well enough. I will look into the astro van clutch. Thanks
Keep in mind that you'll need a bellhousing for an 11" clutch. The more common smaller bellhousing for the 10" clutch won't work. 11" car bellhousings are sort of scarce, and the more common truck bellhousing has a larger bearing retainer pilot hole. There are adapter rings available to allow it's use with the car transmissions. Bob
80's Jeep used a 9 5/8" 14 spline disc. 10 1/2" 14 spline discs are available as aftermarket or custom made. 11" 14 spline was used in 80's Astro vans. S10's used a 9 1/8" 14 spline disc. It's always possible to get a disc custom made. Alot of places out there that can do this and its not as expensive as you might think...
Hey BigBlock..... contact Charlie Chops 1940 here on the HAMB... he has this set up in his little orange track roadster and can give you exacting details on the T5 to Chev 4 mating...........
I had my bell houseing bored over the fit the t5. Why wont my bell housing work? isnt a 153 tooth flywheel a 153 tooth flywheel? Thanks for all the info, I will contacting Charlie Chops 1940.
Mention was made of using the AstroVan 11" clutch. It requires a 168 tooth flywheel. I pointed out that it will require a bellhousing made for the 11" clutch. If your using a 10"/10.4" clutch, then the "small" bellhousing from a V8 or inline six will work as will the 153 tooth flywheel. By the way, what was it you had bored on your bellhousing? Bob
You are talking "153" as in coming out of a Nova or Postal Jeep, am I correct? It should work with the smaller diameter clutches but won't work with the Astro van clutch as it takes the larger bellhousing to clear the pressure plate. We used to run into that issue all the time back when guys were swapping 4 speeds and bigger clutches into rigs that came with ten inch clutches and three speeds. Oops, now the pressure plate and flywheel hit the inside of the bellhousing. I was always under the impression that those engines took the same flywheel that a late inline six, 283 or 327 took but I may be all wet there and learn something that I didn't know today if that isn't the case.
I had the center hole (forgive the incorrect term) bored larger to accept the t5. I using the stock bellhousing from the 153 in a '62 Chevy II I didn't know the 153 tooth could not take a 11 inch disk. That being the case I am kind of back in the same boat again. I can't locate a stock flywheel for the 153, I can get a v/8 to work but I am unable to find a clutch kit to work with the flywheel and a small disc. I have looked into custom build clutch and that is too pricey for me local area I am looking at 300-400 just for the disc. with a pressure plate and fly wheel I am in for 800 bucks or more... too much. Just for fun here is a pic of the engine.
I used a Chevy II bell on my 283 and T-5. Same thing as you, bored the hole for the T-5 nose. I used the 153 tooth flywheel, a common 10 inch PP and the 9 5/8 disc that was mentioned earlier. Everything works well. Frank
The 153 flywheel usually has a 10 1/2" clutch. Jegs and Summit both sell a 14 spline 10 1/2" clutch setup. With the proper bellhousing, you can run the 168 tooth flywheel and an 11" clutch if you wanted to. You can but brand new repop 11" bellhousings on ebay for about $150. Of course, if this engine is going back into a '62-67 Nova, then I guess you are stuck with the '62-67 bellhousing you have due to the fork angle.
My 153 has a 9 1/8 clutch and I cannot find anything other than that. when going by make model engine
Charlie Chops 1940 brought up a excelent point. These engines shake ALOT and the stock heavy flywheel is there for a reason. So I will just have the stock flywheel resurfaced and use a stock s-10 clutch which should mate up fine. Thanks for the help.
Check pressure plate for an '86 Chevy Cavalier HO(I know), if I remember correctly it's what I used with 153 tooth flywheel. 9 5/8ths I think
