Hey guys, I'm sure this has been posted many times before, but I wanna try to condense all of the answers into one thread I have access to all of the parts needed to do the 3100 top end swap on my 3.1, for free...all I would need to pay for is the labor, and I get that at a discounted rate. So my question to all of you gearheads is, how much power is actually gained from this swap? Is it enough to notice a difference or does it only rate on the butt-dyno. Also, how much labor time am I looking at? Because if I can't pay for the labor charges right now I'll just have the nitrous put in and do the top end after the winter. Any input would be great, I'm trying to do as much homework on this particular subject right now as I can. Thanks alot guys!
