Need Help Replacing Crank

Can someone tell me what's involved in replacing a crank? I need to replace the crank on the 1972 Chevy 350 4 bolt that is currently in my CJ. Can this be done with the engine in the car?

Also I see ads for stroker kits, is all that is involved is just replacing the crank?

Re: Need Help Replacing Crank

Car? Yes you can pull the crank with the engine in your jeep, but you still have to drop the transmission. It is much easier to just pull the engine. I think that you have to replace connecting rods and heads to build a stroker, but I'm not sure

Re: How does one replace a crank

The tranny is already out. So what exactly is involved?

Re: How does one replace a crank

I'm not sure, but it would depend on how much clearance you've got under the 350. Some motor mount systems I've seen use a 'cradle' to mount the v8, and there's not much room to get the crank out. If the tranny's already out, it's only a few bolts to take the motor out. [img]/wwwthreads_images/icons/crazy.gif[/img]

As for a stroker kit, I would not recommend changing the stroke on a motor that has some miles on it, as you would risk breaking rings or pistons as you hit up against the ridges from where the rings currently stop in the bore - a ridge is usually worn into the bore.

Good luck
