Yes they are. The 4BT/6BT with a TH400 was a combo used in a lot of bread trucks and similar box trucks.
These kind of posts always help me keep my priorities straight. At this moment the original owner of this very fine 57 doesn’t care one whit about what drivetrain goes in it.
Back in high school a friends brother had a '70 Chevelle with the 450 horse LS6. Lower tune was the LS5 and over-the-counter 465 horse LS7 could be had too. They may be slightly off topic for this site but the General truly did make some great LS engines
Uh, yeah. Back in the late 60's and early 70's LS engines were a different breed, comparing them to the modern LS is like comparing a 60's girl to a modern facsimile (insert pronouns here). Not apples and apples. Back then the LS designation I heard stood for Luxury Sport. They were a hit for us old guys and GM re-used the moniker just like they have reused LT-1 over the years just to mess with us. Hell, they even made modern 396, 327, 427 CI variations just to play with our harp strings. They even put them in cars that vaguely are reminiscent of our muscle cars (wannabes). Make no mistake, not the same engines and not the same cars. Some people say better, but we (the HAMB) are not "some people". I'd take that 70 Chevelle LS6 over the new adaptation any day, all-day...and the real 60's girl with miniskirt and go-go boots for a seat cover while we're at it!
The first LS engines sure got neutered in ‘71 due to “the powers that be”. Ie the Vette LS5 in ‘70 was rated at 390 HP, something like 325 in ‘71.
I have a buddy that into modern LS swaps. It is what the "you tube huddled masses" think they want and are willing to pay for it. It is a troubled time indeed, thank goodness for the safety and sanity of the HAMB. It reminds me of that scene in Pleasantville, the HAMB is our bowling alley. We need HAMB bowling shirts like Big Bob!
I like em I like old engines too. I don’t care what makes it go but I know I can’t post my LS build on this forum. Have one in my step van we’re building. But $350 for a complete set up for a 5.7 is hard to beat with the wiring, column, trans and rear axle. I’m a $1 per HP at this point What makes it go is irrelevant if you dig it. It only matters which forum the pics get posted
Not promoting that whole "LS" thing but you do know that Holley carb pattern intakes have been around a long time, still not HAMB friendly.
I think Ford was close to the first Holley pattern in 57 when at the mid 60’s ones were a direct bolt-on. In 1963 Ford was using 2 Holleys on their 427 so they are way inside the HAMB cut off. Vic Edelbrock was always quick with manifolds especially multi carbs overhead V8’s because it was the go-to prior to the aluminum high rise single big base Holleys in the 6-700 cfm range.
yes and no good sir . while the ls has proven itself to be cheap , reliable horsepower . it looks really funny under the hood of an older car . you might get a pass on a 70’s or newer car . but anything 1969 and older just looks funny with the cop and funny fi intake manifolds . hey I could of had a free ls and 4l60e trans from a work van , chose to buy a carbed 383 , why ? Painted Chevy orange with the correct valve covers and air filter housing will look like it simply belongs under the hood. in reality , I would have built the 235 that’s under the hood now , but building vintage iron has become insanely expensive . and again , I’ll agree with you the ls is a cost effective option , but like a fat chick at last call , you’ll take her for a ride , but won’t be bragging to your friends about it !
Friend of mine loved the large ladies. Married one. He was happier than a puppy with 2 …… I’ve been trying to get my wife to gain weight for years. Period correct/ish build? Nope For a beater to cruise, who cares. Don’t have to worry about looking at a LS in a step van. Doesn’t have a hood. The super low car intake is going to free up floor space. My merc gets a 283 The wife’s 56 has a 350 in the works. The 57 van has a LS mocked up My49 has a 235 waiting on it. It all just chunks of metal with holes.
