Default SO Im pulling the engine.

Yall got me paranoid...

So I pulled the car around to the driveway so I can do it on concrete.

Never pulled an engine out of a C4, how much fun is it to get to all the bellhousing bolts? And where is the best way to hook the hoist up to what is essentially a shortblock?

Looks like a tight fit between the crank pulley and the steering rack...I guess just hoist it steep front first?

Im really going to need some help getting all the hoses and wiring re-routed when I go to put it back together...what a birds nest.

At Summit, what Eagle Street or Street/strip balanced rotating assembly should i look at getting? Im guessing a cast crank, I beam rods, etc will be more than enough for what Im doing.

3' extension with a swivel socket makes removing the bell housing bolts relatively simpe.

The TPIS happy hooker is supposed to work with your L98 as it does on my LT1

Best 50 dollar tool I've ever bought it allows me to pull/install my engine whole (even with long tube EM headers)

Crank pulley has to come off to allow to block to come foward off the dowels into trans.Watch hitting the plastic wiper motor cover on the way up ; many have done it

Why are you buying a rotating assembly? If you are freshening it, rings, bearings and gaskets are what you need.

If Im going through the BS of pulling the block, no way Im putting back the old crank, rods, pistons, etc..

besides, 650-750 isnt bad for a crank, rods, rings, bearings, etc..

Ill go ahead and have the block cleaned, have it bored out, new cam bearings put in, new oil pump..

What's a good oil pump, cam bearings, etc that wont break the bank.

Looks like they would bolt in where the 4 fuel rail bolts are in the L98 intake manifold. My intake and heads are off though.

Ill find some bolts to hook too, might make a bracket that goes into a few head bolt holes or something.

I believe Pete is trying to infer that your factory rotating assembly is much better than a cheap aftermarket one

Well heck...

If I keep the stock crank, Id at least want to replace the rods and pistons, I have to replace the pistons if I overbore it.

I figured...155K miles..rotating assembly must be about worn out..

Pulled mine out on my back with car up on heavy duty jackstands in my driveway after I sent #2 into the oil pan with a little nitrous foopa back in May of 2000.....



And here is proof I got it out all in one piece with the crank pully still in place. Note the special jig on the engine that allows you to tilt the engine to get it out....very important extra $50 tool
