Ok guys this is my first post other than my hello post, anyway i have a 96 silverado with a vortec 5.0, this may have been beaten into the ground already so sorry in advance if its redundant for you guys. I was looking around at some engines and came across gmperformanceparts.com, I found a sb 350 that I really like its a turn key crate motor. The thing is i dont know what all will be involved with a swap like this such as the 700r4 trans. that I have. I know it will bolt up but could you guys tell me some general problems I might run into on a project like this? Sorry for the long post just didnt want to leave anything out.

acutally i did the exact same thing to my 95 everything bolted up computer was compattible everything is the exact same the only thing i changed was my chip to a performance hypertech 350 chip you should have no problem at all!!!

There maybe a little more, I would recommend using the computer at of the 350. For some reason Suzuki-guy's truck does not run correctly

usually you have to have a ECU compatable with your engine. your new motor may not be compatable resulting in sensor problems and performance problems. if you do get a new engine make sure you get your ECU tuned to the right specs for your new engine. also there may be a few re routing projects with your hoses and wires and what not but other than that you should be good. have fun with that 350!

My engine ran fine for 150,000 miles with 305 computer, 350 performance chip. I had it reflashed and tuned at the dealer no problem my engine ran fine its just now having problems 4 years later

Ok I guess I left one major detail out about the engine Im looking at, well its uhm carburated so yea, I dont know how the whole computerized 700r4 tranny with a non computer controlled engine will work out. I know about needing a new bypass style fuel regulator and a bracket for the kickdown cable but im more worried about the transmission since it has a computer controlled O/D and uses the computer also to lock the T/C in O/D. The other thing I was looking at was maybe just tearing down the top end getting the heads reworked and putting a crane comp cam in it and new injectors. But the issue with that is using a 350 cam in a 305. Guess I could just call summit and ask them about that issue but does anyone else think it would be worth it? I mean a fresh motor is good and all but I just want a little bit more out of it. Its my DD by the way.
