Default Post your 75-79 Nova LS swaps.

I noticed there are quite a few disco Nova guys on the forum, so I thought I'd start a thread for us. Post up your swaps!! I'll start with mine.

77 Nova, 5.3, cam, carb, th350, 3800 converter, 4.10's. Full interior, all steel accept for the hood. My best pass so far at about 5k ft DA is a 7.94 in the 1/8. According to a formula my friend has, that's about a 12.45 in the 1/4, but I'm not saying that's 100% accurate. I'd love to run this pig at sea level!!

What do these things weigh? Also my understanding is the rear end width is the same as the earlier Novas and first gen Camaros. Confirm?

Per novaresource.org, base model curb weight was a shade under 3500 lbs in 1975, and just over 3300 lbs by 1979. Add a hundred or so lbs for a V8. They're a little more portly than your typical 1st gen f-body or 3rd gen nova, but, surprisingly, they got lighter as the years progressed.

I currently have a corporate 10 bolt in my 71. It required no modification.

I run an 8.5" ten bolt that's out of another 77 Nova so no mods were required. I've been told disco era Camaros use the same width rears as well. As far as weight goes, I always figured mine was around 3500 lbs, but now that I read the previous post, I'm happy to learn that it might be lighter than I thought.

That is lighter than I thought. My 69 camaro weighs 3500 lbs without me. 69 F-bodies weigh nearly 200 lbs more than 67-68s. From everything I've read the 75-79 Nova has the same rear end width as the earlier Novas and first gen F-bodies, not the second gen camaros. I have not measured to confirm, but I'm curious. I find this thread interesting because where I grew up, I had a couple of friends with these cars and they were my first experience with "muscle" cars. My first swap was a 454 into a friends '76 ss.

4th gen novas have the same rear as 1st gen Camaros and 3rd gen Novas. 2nd gen camaros are longer.

I have a 75 custom nova hatchback that I have had for years. I am going to swap the I-6 with a 350 that was built for a stock car. Any advice and or suggestions would be more than welcome.

Sell the 350 and use money to swap in ls type motor would be my suggestion.

im just doing a L33 5.3 4L65E tranny into my 76 skylark. I already swapped the rear 7 1/2 baby 10 bolt to an 8 1/2 10 bolt with 3:23 gear with posi. rear turned out to be from 80 camaro, i had to cut off spring pads as were closer together than skylark. I also think its 1 inch wider as wheels stuck out little more but barely noticable. im running 15x8 weld drag lights on rear think rear offset 3 1/2 inches. still dont hit 1/4 panel lip.

Hi I'm new to this site, And new to ls motors. And I just bought my first ls. It's a 5.3 from an 02 suburban 130000 miles. It's going into my 77 nova, along with a t56. My first question is, where can I get proper parts like motor mounts, headers, stuff like that, that I womt need to modify? Or can someone point me in the right direction of a forum where I could find his if this isn't the right one? Thanks guys

I have a skylark. shorty headers on ebay work well. oil pan I used a gm muscle car pan its a mistake. hangs way low under crossmember. mounts use someting that drops on sbc mount directly. the plates bolting sbc mount on sets motor higher and 5.3 altenator touches hood. trannel tunnel will need to be cut open for six speed as 4L65E tight fit in my car. I would cut modify truck pan since thats what you have. you could use camaro but probably cut that too. check for inner tie rod clearance for turning . mine did hit pan.
