Well 3 days ago My engine took a turn for the worst and overheated like 4 times and now it's dead. It was a beat up b18a I have another complete head from a 98 ls and a 96 ls Block and I'm putting all the stuff from my old engine that I can use on it. I need to get the piston/rods, clutch/flywheel, and a few other things to put into my other block I have. I stouldn't have any problem putting the b18b block into my car and using the old b18a exhaust manifold should I? I hope not because It's already gonna cost me alot of money that I dont have to put the other engine together....
