Ok I am in the process of disconnecting things to remove my engine this weekend. I removed the 4 top transmission bolts and other things, are there other bolts that connect the transmission to the block? I see a bolt that connects the torque converter to the fly wheel ( just guessing on that one) is that one? looking at the wires at the back of engine bay Bubba has been busy on this car. I am seeing things that just don't look right. Well that's another questing down the road.

There should be more than 4 bolts on the bell housing. Follow it all the way down - the bottoms have to be removed from underneath the car. And you're correct regarding the the TC bolts. There's 3 of them. Also remove the starter - makes life easier. And on that note - if you didn't already, DISCONNECT THE BATTERY!! Lamp

Lamp

Before you start disconnecting everything, make sure you have the trans supported as it will drop when everything is disconnected and you start to lift the motor off the mounts. Most common and easiest way is to use a floor jack under the transmission pan with a block of wood. Jack up until the trans just starts to lift.

Make sure you have another jack handy as you don't want to pull this one out until the new motor is bolted up.

Good luck!! Wink

Yup...six bolts for the bellhousing/engine, and three on the converter. You'll need to turn the engine over(spin it) to get to the other two bolts. Once you have all 3 bolts out, slide the TC rearward to make sure it isn't stuck in the crankshaft.[;0]

As Paul says, you need to support the trans as you separate the engine from it.

OK good advice did not know about supporting the transmission. So far I have taken off 4 bolts on the bell housing and I did not see any others but I will look for them. How do I turn the engine for the other bolts? I already took out the starter and disconnected the flue pump. Do I have to take out the radiator? I took off the shroud.

You should be able to take the engine out with the radiator in place. JUst take it slow. Since you have the shroud off, I'd take the fan off to give some added clearence.

To turn the flywheel, remove the spark plugs so there is no compression. If you don't have a flywheel turning tool, use a lone screwdriver and engage the flywheel teeth and use the starter mounting boss to work the flywheel around to remove the TC bolts.

There should be two bolts on each side of the trans and then one on each side on top at about the 10 and 2 o'clock position. Support the trans under the pan with a block of wood and a floor jack. Unbolt the torque converter. Remove the pulleys and the water pump. Remove the carb and put paper towels in the intake. Remove the distributor and put a rag in the hole. When you disconnect any wiring, make sure you mark them since this sounds like your first engine removal. You have to remove the vacuum lines, disconnect the exhaust, support the engine with a lift and then remove the motor mount cross bolts. Take one more look around the engine and make sure there are not any wires still connected. Now you can remove the engine. Good Luck and be safe.

One thing Ray and I figured out early is to take the engine lift in from the side. The nose is too long otherwise. You may have to take a tire off and support the car on a jack stand on that side in order for the lift to line up....

If you have trouble holler, I just went through this.

To turn the engine can you put a wrench on the front pulley bolt?

Actually, the center crank bolt ( Bottom middle pulley) yes.

I found I could turn mine by hand once I took the plugs all out. Wasn't too bad.

Be very careful using the crank snout bolt to rotate the crank. If there is too much resistance, you can strip out the crank threads and then you are screwed. I recommend buying a crank turning tool. It will bolt to your balancer using the three pulley bolt holes. You then insert a 1/4 inch extension and use a breaker bar or ratchet to turn the crank. No chance of messing up the crank. That tool also comes in handy when you are installing the distributor and reattaching the torque converter. Jim is correct, be easiest way is to come in from the side unless you have alift with a long boom. Mine will reach from the nose with about 2 inches to spare from the bumper.

TAKE LOTS OF PICTURES!!!!

A digital camera is your best friend so that you have an aid to remember what goes where when the engine comes back.

Will just got done with the disconnect process the only thing left are the engine mount bolts. I could turn the torque with my hands that was nice. That was great idea of taking the plugs out. I would had eventually figured that out after I kick the dog and gave the wife a wtf look. As for taking pictures yes I did take pictures of the various brackets but vacuum hoses? The previous owner (Bubba) has so much stuff disconnected it was not worth the time. My plan is to take the engine out on Sunday. Then in the next few months I am going to re-dew the whole front. During that time I will research on whether to keep the 327 or fine a 70 corvette block or just do a create engine. I will let you guys know how my Sunday goes.

Good job!! Keep us up to date on your progress!
As for keeping the 327...why the heck not? They make a really excellent base for a build-up...remember, the 375hp fuelie was a 327!

I agree with Joel and Luke on the 327. IMO, GM never made a better engine.

perhaps a bit of topic, but what are the main differences in those engines and our stock ones beside some cubic inches ??? Confused

About the 327 I heard from some that the 327 was good engine that it had a higher rpm then the 350. The numbers say that it is a 275HP from a 68 Camaro. But I had somebody tell me that it had 283 heads on it. Something to do with 2 crowns instead of 4? I did check with Paragon and they Had heads for 400.00 each I might just do that. Right now I don't plan on doing anything with the engine till Nov. When I do put the engine in I was going to take the car and the engine to the vette shop and let them hook everything up. Just to make sure it gets done right.

If you want to keep the 327, that's great. Does it have camel hump (fuelie) heads? Personally, I would get the numbers off the engine, find out what car line it came in and sell it on the appropriate forum or E-Bay it. Then buy a crate motor. If you are not looking for big horsepower, a GM 300 horse 350 runs about 1,500.00 for a long block with a 3 year/36,000 mile warranty. That's what I did for the 69 and I am extremely happy with it. You add the water pump, fuel pump, intake, carb and distributor and off you go. Runs on regular gas (That will help the wallet). If you are looking for big numbers, there are plenty of builders that sell crate motors for almost any application. The piece of mind you will have over a rebuilt engine with no warranty.

OK the engine has been removed. I did not have any problems with the removable except I had to take off the headers. I did sweat the load on the transmission its still in there for some reason I thought it would stay up. Oh well its coming out today. I can't wait to start on the front end and get that mess clean up. With the engine out there is so much room to work in. I did buy that front end video from Van Steel with that things should go well. I will keep you posted on my progress.

Cool. Good Luck with the clean up. I recommend a gallon of Castrol Super Clean. Spray the entire engine bay down and then power wash it. Oil and grease gets everywhere.

When you wack it all back in, it's much easier to put the engine trans back in as one unit.
