Eng removal LT1/LT4
To add to a previous thread. I spun the rod bearing, and it made
the most sense for me to replace the short block. (Scoggins Dickey had best price). Hood does not need to be removed. 6 Speed does
not need to be removed. Wiper motor does. Label ALL wires. Bell
housing comes out with the motor, no problem. To aid the install: get
2 or 3 longer trans bolts. Cut off heads, and use as guides to align
the bell housing/trans. Fuel lines do not need to be removed. Just fold the fuel rails/injectors etc over and onto the windshield. Radiator does not need to be removed. A/C lines do not need to be removed.
Tip: break the front damper/balanced bolts while accy belt is still on. This create enough resistance to break the bolt.
Engine will run very rough for the 1st minute or so after start up.
Don't let this scare you.
This was my one and only LT4 engine change...and I DID NOT follow
the GM service book. The Haynes book was a better guide.

Did the Haynes manual list all of the torque specs for every bolt when you re-installed the motor?

Also the six speed needs to be removed but I think you just mistyped that.
Oh and Haynes manual is better? You are the first who's ever said that!
Glad you had success.

No the 6 speed does not need to be removed, I have done this several times and my trany has never been pulled out of my car. I have also never had a problem with the wiper motor on my LT1 cars either.
Here is a shot of my LT1 hotcam motor before we installed it and the 6 speed never moved

like I said
the 6 speed does not need to be removed.
I pulled off the crank pully and vibration damper
prior to removal. This gives you more room to slide the engine foreward.
And yes, the Haynes book was a better scource than the
GM service manual. (in this case)

I just pulled my engine last weekend and did not pull the tranny i have a 6-speed. I did pull my hood off because i like the extra room to work on the front of the engine. This is the 5th time I've pulled my engine. I did this one in about 7 hours by myself. I only pull off the front pully not the dampner and it still clears the front crossmember and i have the larger dampner because of the 434 engine.
