you trans can work. there are other posts on that topic as well. basically, if you use your stock tranny there is a possibility that it wont last. as for the bellhousing, it does bolt up. a few holes dont line up, but there are enough for it to work.

none of your accessories will not work at all.

All lsx based motors will not fit your accessories with stock brackets. At least you have a 4.3 and the radiator still may work, throttle and cruise cables work, fuel lines/ pump work. Hell I had the 2.2l and had to get lots of stuf you won't. Most people need to get a driveshaft cut I didn't need to my driveshaft fit prefect. One last thing is you should have posi and you may want to find a 8.5 rear with 3.42 or 3.73 cause 7 5/8 will work just how long?

what about smog . i want to buy a crate motor but do ls1 crate motors come with smog pumps or do i need to buy that separatly. and what about the a/c and alternator

First off look at this link the cheapest crate you can get is a LQ9 at 3,749

Second you should goto this link and read alot about this engine swap

Since you are worried about smog my opinion is that you should buy an engine trans from a wreaked 2001 or newer lsx based vehicle with transmission which will be about the same price as a new crate. If you get a corvette engine you have to get different headers and a camaro throttle body. If you get a motor from anthing else you have to buy all the corvette accessories and headers. Also, when doing this swap you have to decide on a different oil pan. modified 5.3 truck pan is what most do. I did a ls2 corvette oil pan cause there are no clearance problems with a bagged or lowered truck.

are ther any other v8's that will go in a little easier. maybe from a newer truck like a vortech 350 or anything else

the accessories that will not work are alternator, power steering, a/c pump. tensioners and idler pulleys will not work either. i believe that is all there are for accessories... if you consider anything else an accessory, let me know...
