Post your questions so we can discuss.Β So I've got two avenues. It's got an old 350 tranny under her now. I know nothing about other than when she had her 350 motor it rode down the road on short quick gas can run. I've had a few g-body Monte Carlos and have always struggled with the kick down or indent cable. So I went out and got a 4L80 I figure that be good enough to hold that big block. But I didn't account for needing a stand alone tcu (computer). I also know the drive shaft will have to be modified if I got the 4L80 route. But is there a way to use it without the comp? It'll hook up to 850 Holley carb. So for wanting to drive it's sake I thought maybe pulling out the 350 n rebuilding her with stage 2 goodies. But I'm not mechanic and I've never rebuilt one.Β Β Which route would be the painless of the two?Β Quote Link to comment Share on other sites More sharing options...

Love the garage,, nice and well organized, looks just like mineΒ All good workspaces are a mess right lol. It's actually my buddy's garage. So me not being so mechanically inclined for shouldering most the weight of the mechanics I'm trading him my 88 Monte (which he's LS swapping ATM.) For the work on the 70.

MC1of80 Posted December 18, 2023 Share Posted December 18, 2023 I believe you can use the 4L80 without a computer BUT it needs to have a manual valve body. Not 100% sure on that.Β Th400 would be an ez swap out the th350 upgraded would work for a while depending on how you drive. As far as the "kickdown" cable the th350 will work without it being hooked up without danger of cooking the trans. BUT in order to "kick down" you would have to drop a gear, from drive to 2nd and go.Β 1 Quote Link to comment Share on other sites More sharing options...

MC1of80 Posted December 18, 2023 Share Posted December 18, 2023 Yes manual valve body. Meaning you control the shifts. It no longer does it automatically. Including every time you come to a stop, you HAVE to start in low and work your way through the gears. If you start in 4th, 3rd or even 2nd you most likely will cook the clutches and make the trans useless.Β Pros and cons of our addiction. π³ Quote Link to comment Share on other sites More sharing options...

Put the 350 back in while looking for the 400 ( you are looking for anyway) and drive it till you kill the trans. At least then it will move on itβs own power and you can focus on the rest of it.Β 3 Quote Link to comment Share on other sites More sharing options...
