Lm7 in c10 trans question Building a mild street truck out of my 85 c-10. Going to drop a 5.3 in with a carb. 219/228 ls1 hot cam possibly. Want to go biggest cam without having to do a big stall converter. I'm trying to keep trans as simple as I can but I doubt the turbo 350 will hold up. Any suggestions on a trans that is a pretty easy install

I know I will have to get some adaptor engine mounts to get the 5.3 to fit. Once the tranny is bolted up will the driveshaft still fit or will I have to change some more stuff out?

If you have the cash, a 4L80 is totally worth it, a used one for 600$ will hold 600 HP of it is not a 400k mile worn unit. The one in my 86 YA had 198k miles and works need ect behind my 5.3 with a cam.
A th350 will work perfect if it is rebuilt, and if it has low miles it will hold as long as you aren't beating it to death.
A th400 and 80 would require drive shaft length change. Otherwise a stock location swap plate setup will keep the factory drive shaft length and fit like it was made for the truck as mentioned.
