holy crap bigtimmay, remind me not to mess with you, i dont even bother trying to mess with my dressed 2.3 cause i cant move it, while its out thoe i will weigh it so every one knows, i mentioned the 3.0 24v duracrap because of the all alumanim cunstruction and its mabe alittle lighter than 200 not dressed but with intake and exhaust, winds high and puts out quite a bit of power, ls1 is a good choice too thoe, we are guna be putting one in my friends bimmer, those are cheap and so easy and light, just make sure you get the right one, the trucks have diferent cranks and are usualy the cast iron blocks, so get one out tof the 1998 or newer cars, and some of the trucks came supercharged and that will bolt on too, and if you have money to blow, here where i live the company my friend works for made the first 500 ci ls motor and they build them any way you want them.
