View Full Version : Pulling the motor

11-22-2010, 09:35 PM
What exactly is the easiest way to pull motor? Dismount it from trans or pull the trans too? Probably going to buy myself engine stand and hoist and just do the work myself than take it to shop to have it dyno tuned.

How intense is it rebuilding the bottom end/upgrading? does the haynes manual cover most of what I need to know?

um. its prolly one of those things that if ya have to ask....

but when i did it i just took the 7 or 8 bolts out that hold the block to the tranny. there is one opposite of the starter thats facing toward the drivers side. took me a bit to discover that one. and a good amount of extensions too. All and all it was a easy task. Didnt mess with the bottom end but ive rerung a few SBC's and its super simple. Just gotta be clean and make sure you properly torque everything down. And invest in some plastigauge. Its only a few bucks and its worth the extra time and money to make sure your tollerances are correct.

Well I figured I'd ask with you guys being "Grand AM" owners, a lot told me to pull the trans + motor, some say just motor.

just motor.......

but you are pulling the motor to have it dyno-tuned? If its already in the car, why not just trailer the car to where you need to go.....

i thought u sold everything? to rebuild anything.

If all you need pulled is the motor, then it's easier to just take the motor out the top with a cherry picker. If the trans hasn't been built up I'd pull that too though and rebuild that. And IMO most Haynes, Chilton, and the like aren't worth crap. They are far less detail than the factory manual. You can find them used online, so if you are going to get into serious work get a GM factory manual.

If you are NOT going to do tranny work lift the motor out. Otherwise you may as well drop the whole cradle and deal with everything...

GM Service Manuals are GREAT, even at full price from a local dealer can save you many hours.
Sometimes it's worth getting friendly with the parts guys at a dealership, 'jobber' price beats retail.

Good Luck

i dropped 3 g's in the transmission during the summer, thats one of reasons i'd hate to just get rid of the thing, to much money involved already, Might as well finish what I started get some #'s and Times that i can happily say i did it and than maybe move onto a new project. I'm going to have to say i love cars more than i love racing quads lol.

if you have a hoist drop it out the bottom witht he whole cradle

if no hoist out the top by it's self just did it with my car no previuse experiance with a N-body at all.

just make sure you have like 10 extentions for the bitch bolt. it's a backwards facing bolt between the eninge and trans and have to go in through the wheel well PITA

also here is a site with most GM manuls digitized and free

the bitch bolt is easier to get to on a 3400 than a 3800.

11-24-2010, 04:04 PM
^This. Done it on both cars, and it's def easier getting the 3400 out the top than the 3800. :)

11-24-2010, 04:56 PM
yes on both accounts.

i hated removing the 3800 in my old GP

depending on how fast i sell my quad, I'm going to slowly get parts without having the mother load of cash from it. Once that happens, I may have a few questions to ask on the bottom end. 12's jackpot is still ago? I hope cecil or atco are open in time :D
