is the 1960 cast iron with a 235 the same bolt pattern as the aluminum with a 250 chevy i'm swapping engines and want to use the 250 inplace of the 235 and really don't want to h***le with drive shaft and trans mounts. this is going in my 1960 bel air trying to keep this a low budget build.
well if you use a short alum powerglide and the 250 engine that may hook up ok but you will have a length problem on the engine proabbly not really a bolt in instalation but would update the vehicle
thanks for the replys i figured it out tonight after i pulled the engine. tomorrow i will measure everything and see what i need. here is a picture of the old 60 http://s1255.photobucket.com/albums/hh635/jmb68/bel%20air/
It may be possible to adapt your 60 Powerglide to work with the 250. If the 6 cylinder Powerglide bell has the same bolt pattern as the 8 cylinder Powerglide (not counting the adapter plates), then it might be possible to just use an 8 cylinder Powerglide adapter plate to adapt to the newer sixes and of course the Chevy V8s. I will check on this as I have both adapter plates, along with a 58 Chevy V8 Powerglide.
the bellhousings are different. The 6 has the indent for the starter way up high, the 8 has it down low. I would swap the engine and transmission complete, and I'd see if I could find the V8 brackets to bolt to the frame, and the truck type engine brackets, to mount the engine. Then all you should need to worry about is the driveshaft length and yoke spline count. And you could use a th350 instead of a PG, if you want the car to have a little bit of acceleration. The extra gear really helps.
the acceleration isn't no big deal to me. i thought about the th350 but i already have the 2spd powerglide in my possesion.i'm getting ready to go out side and start to do some figuring and make what i have work.
well the old cast iron is 24 inches long where the newer aluminum 2spd powerglide is 29 inches long the blocks are the same length 31 1/2 or 32 1/2 (can't remember now) thats from the front of the harmonic balancer to the back of the block but keep in mind i took off the plate on the 235 trans plate adapter?? it is 2 inches wide so it looks like i'm goping to be cutting the drive shaft for fitment. hopefully i will be able to use my shifter linkage the worst thing is i'm doing this in my drive way i have a 7/8 plywood for my engine hoist to roll on but the good and best thing i've got going is my 22yr old son who is built like a ox is there to help.all in all this is very fun for me. tomorrow i'm taking some pictures of the progress.
You can bolt the iron 'glide to the 250 using the bell from a '60 or so V8 'glide. Did it years back with a '62 six banger trans and a 348.
You can, but beware that you'll be taking the transmission half way apart to swap that stuff, since the valve body bolts to the back of the bellhousing. I'd rather work on a driveshaft...
well ****** is in have to cut drive shaft no big deal but now needing a yolk the the old one is smaller splined shaft than the aluminum powerglide looks like i'l e heading out to the junkyard next saturday. so now i'm just going to place the nengine in the car to see what i have to do for mounts.
If you could have found a 62-64 FULL size p***enger car aluminum Powerglide, those are 25 inches long (for the "X" frame cars), you could have gotten by without modifing the driveshaft, and probably still used the course spline slip yoke. I just happen to have a 25 inch long Glide that was originally in a 63 409 car. You could have used the cats iron Glide, but it requires a lot of work. Cast iron Glide: Stater adapter plate, bellhousing, main case, extension housing. You would have had to use your extension housing and main case, and a V-8 starter adapter ring and bellhousing. Sounds like you have it handled now however. Butch/56sedandelivery.
well this project is going smoother than i thought.getting the drive shaft cut this week our local welding shop qouted me a good price on everything.my plans where to have this running by june 15th (my birthday) and it looks like it's going to happen i'm actually comming out ahead on money with this so i';m thinking about ordering a 4 barrel manifold for it or the split headers don't know which one yet.
