I need help fast, V8 to 6 cyl Powereglide.

[Nads]

I just yanked the engine out of my '60 Chevy wagon and the bellhousing on the PG doesn't even come close to matching the V8. Is there a different bellhousing I can get to mate it up?
The flex plate is way smaller on the V8 too, there's no way the starter would mesh.
I was told by some good folks here that it would be a drop in.
If I have to get a new tranny, which one will be the right one to replace the PG dimension wise.
Will the driveshaft splines be the same.

Thanks.

Nads,The small flexplate takes the starter w/ the parallel bolt holes.(Usually found on 6cyls,)It is the 152 tooth wheel.A short tail TH350 trans is a good replacement for the PG. Charlie

Starting at the beginning, Chevy V8's from 1955 to 1961 all used a cast iron bellhousing, 168 tooth flywheel, and three-bolt flange mount on bellhousing starter. These bellhousings all had a 4-11/16" diameter transmission locating bore. These all interchange and will also fit V8's up through the present (except flywheel for the 400 c.i.d. small block and 454 c.i.d. big block).

The Chevy "Blue Flame" (235 c.i., etc) 6 cylinder engines used from 1950-1961 will not accept 1955-1961 V8 bellhousings or flywheels or starters.

yeah i agree ,, why not use a 350 the spline shaft is the same 27 splines on both powerglide and turbo 350 The Powerglide and the TH-350 use the same 27-spline output shaft and are the same length. The TH-350 has a steeper 2.48 First gear. The two-speed glide offers a 1.76 First. Six-cylinder ’Glides use a 1.82:1 First gear. the yare both 27.75 inches long , the yhave shifter conversions for the column indicator and it is a sweet swap http://www.chevyhiperformance.com/techarticles/60978/

Nads, as stated in previous posts and through your own experience, the bellhousing pattern from a 235 and a V-8 are different. However, the easy solution, like already said, is to convert to turbo 350. Same size output and length, so it is a bolt-in from that standpoint. You need to mess a bit with shift linkage and maybe add cooler lines and a cooler, if your trans is an air-cooled model. The kickdown cable is only for kickdown, you can figure that out later, it will run fine without it. You do have to hook up the vacuum line to the modulator, which is located at the rear of the trans.

The turbo 350 gives three speeds, and the lower first will really help get that big car going easy. They are cheap and everywhere in the junkyard. They are alum case which is much lighter than that old cast-iron thing you have now. So better gears, cheaper, lighter, and almost a bolt-in seems like the choice is pretty easy to make.

I'm getting a TH 350 from a rebuilder in town, $350, man the bills is piling up fast. I guess it's time to kiss that old antiquated shit goodbye.
He told me the splines on the TH 350 are fine and the PG is coarse, no problem, I just have to get a new yoke. However he said the TH 350 is shorter so I have lengthen the driveshaft.

Man, I'm so confused, I want my daily driver back.

I guess I have to drive the bone rattling '34 until the '60's back on the road.

Ain't old cars a heap of fun????

dam sounds like your having fun again. http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

Dude Grinder, I'm covered in grease, I'm too old for this shit. You coming out in two weeks to do Vooddo's eyebrows?
Does anybody have any idea how heavy a cast iron PG is?
Somewhere between Oprah and Jared, the Subway Sandwhich guy.

Oldchevyseller, I checked the splines on the output shaft of the PG and I counted 17, give or take 2 in my drunken state.

I have to say that because I'm a Chevy guy to heart, we still have a lot more interchangeability than some others.

Shit, it's just money, the old girl will be back on the road soon.

The way I see it is that even having 4 old cars with zero payments is better than having a Lexus with payments that requires ROCKET SURGERY to fix.

Are you saying the front splines are the same, so PG and th350 take the same torque convertor, or am I reading wrong here?? http://www.jalopyjournal.com/ubbthreads/images/graemlins/blush.gif

I had an aluminum PG a couple years back and I KNOW the 350 convertor doesn't fit, and I even contemplated buying that adpater thingy shaft from Summit so I could use the far more available th350 performance convertors. I'm sure the tail shafts were not interchangable either, but not positive.

[Grinder]

yeahI want to be there to work on voodoo's love mobile. what date what time ?What nads was trying to do was just an engine swap.To make life easy .Not the whole tranny driveshaft redo everything bullshit boogie.Boy it's going to rock with that v8.No more getto shmoozing you'll be super slab crusing http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[Nads]

Okay, my boy Mike's got an aluminum PG out of a '67 El Camino, will this thing fit?
I'm worried about the torque converter now.
I'm going to his shop later on to check it out. I'm keeping my fingers crossed.

you are wrong, misunderstand, bad information given / received. Common on the interent for some strange reason... LOL

Input shaft splines are waaaay different from glide to the t-350

Early glides had a course spline output shaft, not the same as a T-350. Even the early aluminum glides had a course spline output shaft.

[Nads]

That's what I thought, I don't mind changing the yoke, a simple enough operation.
So what about the converter? I have a flex plate on my engine, it's in good shape, the teeth aren't buggered up. The engine's a '62 so it would've been running a PG, unless it was changed in it's life. But the guy who sold me the engine said it came out of a stock '62 Bel Air sedan.
What starter do I use? My engine has starter mounting holes from the bottom.

Right now my wallet's bleeding. All I want is to have it on the road by the end of the week.

PS the Chevelle website has some bad info on it, the output shaft on my old PG is definately coarse.

[oldchevyseller]

no i never said the input splines are the same!!!they are not . the output splines are!!! it is in my post http://www.jalopyjournal.com/ubbthreads/images/graemlins/shocked.gif

[oldchevyseller]

let me ask you are you sure you dont have a turbo glide? not a power glide , that tranny was availble also,what does your shift display look like in your car??
