Stock bellhousing with new clutch

I've got a 350 SBC that I'm swapping into my 92 Camaro attached to a t5 transmission with a 10 spline input shaft. I was able to get my hands on a manual stock v8 bellhousing, however, the 350 that I have has a 14" flywheel. is there a clutch/flywheel combo that would work with the stock manual v8 bellhousing? Will that bellhousing even work with a 14" flywheel? If not what bellhousing would be good? The reason I got the stock v8 bellhousing is because of the clutch slave cylinder mount. Is there a way to get around that mounting if I were to get a bellhousing without that mount?

I am also having problems with the starter matching to the bellhousing, as the starter sits too high to slot into the bellhousing. Is there a starter that would work with that? or is there a possibility of shimming the current starter to fit?

Re: Stock bellhousing with new clutch

The stock T5 bellhousing only fits the 153 tooth flywheel. You did not mention if your 350 had the one piece rear main seal or the two piece but a quick search on Summit will show you both styles available. Easiest to use the parts intended on your car as its readily available and made to fit from the factory

a t5 transmission with a 10 spline input shaft
Yuck... a crappy 6-cylinder transmission. You'll hate the terrible gears and it's likely to tear up real quick because it's even weeeeeeker than a V8 one. Good luck.

the 350 that I have has a 14" flywheel
Not a problem. Unbolt it and throw it away.

is there a clutch/flywheel combo that would work with the stock manual v8 bellhousing?
Yes and no. You can't buy a clutch kit that will work, but you can piece some stuff together and fake it. We'll get to that.

Will that bellhousing even work with a 14" flywheel?
No.

If not what bellhousing would be good?
Wrong question. Can't get the right answer unless you first ask the right question. You already have the only bell housing style (in stock BHs, anyway) that fits your car. The correct question is, what flywheel should be used with THIS bell housing. You don't need any other BH.

Is there a way to get around that mounting
Not that I know of, at least, that you can "buy"; something could probably be made though. But there's more to what you need than just that. The trans needs to be rotated toward the driver's side about 18° or some such, otherwise the torque arm won't bolt up to it. Similarly, there's ways around that too, but at some point, enough is enough. Forget using the truck flywheel and do it right, or at least that one part of it right (using a 6-cyl trans behind a V8 is pretty much the definition of NOT right), then you won't have to worry about all that.

Is there a starter that would work with that?
Yet another thing that devolves from trying to graunch the wrong flywheel into the car, and the slippery-slope cascade of "oops this wrong thing I wanna use doesn't fit so I gotta change this, oops if I change this then that won't fit either, oops when I change that then the other won't fit either" you've worked yourself into.

or is there a possibility of shimming the current starter to fit?
No, of course not. All that shimming does is adjust the starter position to make up for sloppy machine work at the factory, specifically variation in the distance between the crank centerline and the starter bolt pattern. It won't make the wrong all the rest of that stuff work.

is there a clutch/flywheel combo that would work
Sort of. For a short while at least, until that crap 6-cyl transmission tears up. So, I'm guessing then, that you had a 6-cyl T-5 car, and you're swapping this 350 into it? I'll proceed under that assumption and list what you DON'T have at this point and leave out the 6-cyl stuff you can re-use like the console, pedals, torque arm bracket, crossmember, hydraulics, etc.

  • Stock flywheel for Camaro/Firebird V8 83-85, if your 350 is from 85 back, and has the 2-piece rear main seal. It'll be a 12.8" w/ 153 teeth. You'll find that there are 2; one was used in the grocery-cart LG4 cars and weighs about 22 lbs, the other was used in the performance oriented L69 cars and weighs about 16 lbs. You'll want the light one. Although with that crap 6-cyl transmission, you'll find that even that is far in excess of actual need. If your 350 is 86-up with the 1-pc RMS, you'll need the stock flywheel for 86-92 Camaro/Firebird V8 instead, and again there are 2 weights: one for the TBI & LG4 grocery carts, and one for the performance cars. Throw the one that came with that 350 in the trash.
  • Stock clutch (cover, pressure plate, & spring assembly) for a V8 Camaro/Firebird 82-92
  • Stock clutch disc for a late 80s / early 90s S10 (pretty sure you'll only find this listed for the 60° 6-cyl since the 90° 4.3 only came with an auto... Astro vans however might have had the 4.3/manual combo available, I have no idea)
  • Stock throwout bearing for a 82-92 Camaro/Firebird V8
  • Stock pilot bushing or bearing for a stock Chevrolet V8, 1955 - 2000
  • Stock 84-92 Camaro/Firebird V8 bellhousing (which you already have)
  • Stock starter for 83-92 Camaro/Firebird V8 w/ T-5, or (HIGHLY recommended) the one for about a 96 Vette or 98 truck
  • A V8 tach if your car has one of those, and you care whether it reads right or not
All of this is stuff you can get at RockAuto or your local parts store or Summit/Jeg's or wherever, except the BH, which you will use the one you have; and the tach, which is VERY difficult to find one that works right and doesn't read like twice the actual RPMs and somebody is willing to sell. But that's not particularly urgent anyway.

Re: Stock bellhousing with new clutch

Just a FYI a clutch from a Monza Spider v8 will have the correct tooth and size needed for the V6 trans you are using

I like it, blunt and straight to the point. I appreciate the help, all of this will come in very handy.
