Anyone done this? went from the v6 to the lt1 carbed? I'm in the process of doing this and I almost have all the parts together. If any has have you had any problems? I'm going with a th-350 transmission that is be rebuilt. I have all aftermarket Autometer Phantom gauges. Please let me know of any troubles I about ready to pull the old out and in with this beast. Would I have to change drive shafts thats one im not sure of.

thanks for any heads up.

 

Im doing a fi v6 to carbed v8 swap but mine isnt an lt1. Same difference though. I dont think you'll have to change the drive shaft. I know i dont, i could be wrong though. But hey, have fun!

btw from what everyone says getting the old motor mounts off is one of the hardest parts.

 

i just cut the head of the bolt and POOF the mounts fell off. but getting them on was a different story

 

There is someone else who has done it but I can't remember their name. Going to a carb greatly simplifies the whole swap, but if you want a/c you're still going to have to notch the frame. With a TH350 I think you'll need to a longer driveshaft. If that becomes a problem let me know, my brother had a custom one made in Houston for his car for I think $100 that was supposed to be good to over 500hp. I think. I'll check with him about it. Also, you'll either want to get a very good fuel pressure regulator, or get a fuel pump designed for a carb. Other than that, I don't think you'll have too much trouble doing the swap.

 

The TH350 has to have a 9" tailshaft, or you'll need the longer 200r4 driveshaft, or lengthen yours for like $65 at a driveline shop.

 

should be a direct bolt in with the 9" shaft ...the 6 inch gives you the problem.

oops thats what you just said eh twilight!

 

Do you guys know if a 2nd gen drive shaft would work? My friend who gave me the tranny has a few of them. He said it works with the tranny?
