Post your questions so we can discuss. 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. Which route would be the painless of the two? Quote

Love the garage,, nice and well organized, looks just like mine 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. Sure is beautiful seeing that car 28 years apart! 3 Quote

Based on what I see you’re the Joker. lol. 😂 ( p.s. to all I know Adam personally, he’s even been to my house). Definitely is a joker mention 🙂 when I do the cowl I'm gonna tuck a joker card (painted) on it. Not to big though 😂 Quote

MC1of80 Posted December 18, 2023 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. 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. 2 Quote

So manual valve body? I've read and seen the term, but is it actually making it a manual? Or I was hoping Holly would make a bracket I could put on the throttle body. Quote
MC1of80 Posted December 18, 2023 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. Pros and cons of our addiction. 😳 Quote

There you go. 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 it’s own power and you can focus on the rest of it. 3 Quote
Dtret Posted October 18 Posted October 18 I’m posting for Adam I took over the build of this car because for some reason progress halted for an extended period of time with no restart intended. Stuff happens. We picked up the car and parts in April and brought them my house. Things have drastically changed since then. We basically decided to scrap the car( although it’s still sitting out back) because the floors were all riveted and screwed together. Every valley in the body was filled with spray foam, sealed and primed. The exterior, all holes and rust were just covered with bondo. And the frame was completely rusted. It was a Michigan car. We cut a deal on a different car. So I have been building a car for him. It won’t be a restoration but it will be a decent, safe car. I don’t have a bunch of pictures but I’ll post a few. 8 Quote

Dtret Posted October 18 Posted October 18 The cinder blocks were just holding the body up until I could get my little trailer under it. No work was done on the body. 4 Quote
FrankOC Posted October 18 Posted October 18 I don't think Ive ever seen chocolate pudding used as a gear lube. Keep the pics coming! 2 7 Quote
Dtret Posted October 19 Posted October 19 That rear differential kinda shocked me when I pulled the cover off. I was just going to reseal the gasket. Well that didn’t go as planned. Surprisingly there wasn’t any damage. Funny thing, when we were looking over the car Adam said he wanted to get a 12 bolt for it. I crawled under the car and informed him that it was a 12 bolt. Not the preferred 12 bolt but it’ll do for now. 2 Quote

willie Posted October 19 Posted October 19 Dennis looks like you are doing a great job helping Adam!!! I think i will bring one of mine up to you and drop it off. It needs the same thing and then some!!! As far as the blocks and 2x4s, as others said, not the best scenario. But i have to be honest, i have done that also but it was oak 3x3. Still not perfect but you do with what you have. Like you no work was done on the body but that's how i got the body separated from the frame. However your 2x4 needs to be longer!!!!!!!!! The rear end chocolate pudding is frightening, glad that all worked out!! Certainly didn't think that was going to make it!!! Keep up the good work!!! 2 Quote

420ponies Posted October 19 Posted October 19 If you're looking to use your Turbo 350 it's a Definite Yes! I know of many big block/ turbo 350 combinations in the past. The best thing is a Better 1st gear ratio! They are very strong upwards of 600 hp. Knowing what you want, I don't think you're looking at that hp range ( right?) . An 850 cm on your combo is a little too much in my mind. A 750 cfm is more than enough for upwards of 550 + hp. A 2 Bolt bottom end is capable of 600 hp, if built right. Is it a nodular iron crankshaft? Good " H" beam rods are the ticket. I'm concerned about that piston choice for the build. What camber heads and what camshaft are you going to run? . Do you have an engine shop near you that can help with the build? There are some very good shops in your area that can help with what you want out of your engine in this build. My build, 427, nodular iron crankshaft,454 block, 396 crank, " H" beam rods , flat top pistons ( valve relief for the intake), 10:2 ratio compression (.030" gasket), with '69 427 closed chamber heads. Dual plane ,air gap intake, hydraulic roller camshaft, . 567/.578 lift , .112 lobe separation. I'm running stock manifolds that work better with these closed chamber heads. Back " in the day " we had a similar set up in a ' 70 Nova ,and it was a 11.90 et 1/4 mile Street Car !! With this set up, I'm guessing a 12.60 et 1/4 mile car with the added weight!! There are a lot of "added" tricks to make a turbo 350 perform at this level, just have to find a good transmission shop/ builder in your area. I'd check out some bracket racers in your area. I know, lots of information, but I always have ammunition going in. Hope this helps with what you want.😊 6 1 Quote
