I've pulled several siezed engines out of GM trucks,as the others said,all you need is a little more room up front--all the ones I pulled I just took out the radiator,didnt need to strip the front of the motor down,but different years may be a different story.I suggest you buy at least 2 bags of speedi-dry or cat litter for this job--your going to need it--a lot of dextron in that coverter,and you will have to hook your engine hoist nearer to the front of the motor,so after you pull it back enough to disengage the converter it will lift the front of the motor up,reducing the amount of clearance needed in the front.I've tried pulling the tranny with the engine on a 4x4 before,its not easy--the tailshaft splines arent always easy to get out of the adapter(on one truck I cracked the tailshaft on a nice TH350! /forums/images/graemlins/blush.gif /forums/images/graemlins/angryfire.gif)and you have a hard time extracting both together out from the engine bay--Its easier to just pull the engine and converter,and sweep up the resulting mess,in my opinion.Some folks take the nose right off,its only about ten bolts,but I never have,too hard to lift it off alone!. /forums/images/graemlins/crazy.gif
