Found a replacement engine, any tips on removing LT1?
Well I posted on my fun night at the track where I spun a bearing about a month ago now.
I found a replacement
I was turned onto it by a local shop that I trust and who built it.
355ci
cast crank
stock rods arp bolts
speed pro pistons
ported out heads with bigger valves
custom grind comp xfi cam
engine made 411whp in previous car.
I even got to hear it run in the car
soo....Any tips or things to remember when removing my old motor?

No matter which one you have, I suggest HAPPY HOOKER its inexpensive and the best purchase I've made for a C4, it cuts hours off of an engine pull.

If your engine is stock you should be able to pull it as a complete unit (even the exhaust manifolds)

basically disconnect all the water hoses, AC lines, fuel lines and electrical connections, unbolt the gearbox and engine mounts
slap the hooker and engine hoist wiggle it a bit and it should "pop" right up

since I have LT headers, and an electric water pump, I have to remove them in order to pull the engine.
I remove the damper to pull the engine far enough forward to clear the tranny. Don't forget to support the tranny prior to disconnecting the engine
Good luck
Mike

I did some LT1 pulls on a couple of different cars prior to buying a happy hooker and wish I had one from the beginning. I use mine enough that if I lost it I'd buy another, even if it was 4 or 5 times the price.

OK, I want to yank this sucker out with the least amount of work, I plan on dropping it off fully dressed to the machine shop, they are going to do their thing and give it back to me fully dressed ready to drop in. Some people have not removed the tranny (Manual) and still manged to do it, your saying the flywheel makes it a pain? How much of a pain? Will removing the damper give me enough room? I want this to be a half a day thing, then half a day back in.

I don't think there's any way to get it back in with the tranny on while the hood is still attached. I kept the flywheel on, but took the bellhousing off. Does your half day estimate include hooking it all up, plus installing the tranny, driveshaft and doing the C-beam?

Do yourself a favor. Drop the tranny, bellhousing, clutch and FW out from the bottom. Its not a big job (took me about 30 mins) and makes removing/putting back the engine a lot easier.

Alright, I agree removing the tranny is a good idea, I don't have a lift so this will be done with jackstands, and a tranny jack, can I roll the tranny on its side to get the shifter to clear? I am not superman, but is that manageable or should I find a victim to help me?

ZF6 is pretty heavy and doing it on jackstands, your going to need help.
