I've been a long time lurker, but I finally registered. I see there are plenty of knowledgeble people here, so hopefully you could help me out. My 95 4.3 has now 249k on it, and altough still running very well (knock on wood), I do wonder what the "life expectancy" is... So, seeing that an LT1 swap is fairly inexpensive and pretty easy, where in the NYC area would you recommend I pick up a used engine? Is 249k something to be scared about? The car is properly maintained, and I've encountered very little in the 2 years I've had it in terms of problems, heck, I think even the tranny is still original... So, sorry for the long post, but what insight can you give me? Places to get parts?
