LEON, you must not have read the 1st post lol. I said "daily driving" and "mpg increase". Im not gonna hot rod a crew cab 3/4 ton truck. I wanna drive it daily, im all about saving money if i'm able. Still leaning toward keeping my TH400 because i wont have to move it and its a beast compared to a 4l60e. I dont like buying parts more than once lol. |
Re: 454 vs. 5.3 efi vs. 5.3 carbed
Guys, im sorry, i have no idea how to multi-quote or whatever its called. Still leaning on 5.3/th400. I get mixed reviews on 4l60e. Plus if i do that i wont have to move my trans x-member or cut my driveshaft. I can find a set of 3.08 gears and be turn low rpms, all my driving is 45-60mph at the most.

Re: 454 vs. 5.3 efi vs. 5.3 carbed
the 4L80e is like a turbo400 with a OD. Or go all out and get a 4L85e...its even stronger.

Re: 454 vs. 5.3 efi vs. 5.3 carbed
Well if you're looking to JUST save money, go with the 4.8 or 5.3! If you want more power later, add boost! BTW, swapping an LS motor is not exactly saving money ;)

Re: 454 vs. 5.3 efi vs. 5.3 carbed
okay...lets learn something today. lets say............................
10mpg @20,000 miles vs 15mpg @20,000 miles. If i drove 20,000 miles and had an extra 5mpg and the cost of gas was 4$ a gallon, id save $2,668 from my little quick math i just did. Also take in consideration that i'd tell my motor/trans and that'd cover alot of cost also. I noticed 454s are not cheap. It's about saving money for the most part,but its hard to throw the thought of a LS swap away when 20,000 miles of driving pays for the whole swap and the BBC/TH400 is extra money lol. Its going in my 67 btw so it actually just makes that project cheaper lol. |
Re: 454 vs. 5.3 efi vs. 5.3 carbed
LOL. I'm going to daily drive mine. But you can't go wrong with the 5.3. I understand the 4L60 is not very strong. The TH400 is definitely stronger...you can always add that over drive...I forget the name, but they are about 2200
In either case, you are doing the right thing. Posted via Mobile Device |

Re: 454 vs. 5.3 efi vs. 5.3 carbed
You know, I see all these guys saying that the BBC brings the cool factor to the people looking at our trucks. Let me just tell you how many people are shocked and blown away that there is a LS based motor in my truck.
There is a local car show that I drive my truck to. There are other 60-72 Chevy trucks there, some SBC, some BBC, but only 1 LS based truck. Even with mine looking like a total POS, mine gets the crowds. Maybe it is because it looks like a pile and then people are shocked with the LS? I think more people are seeing the LS in these trucks as cool vs the BBC. But hey, maybe I am wrong. Oh, and you know how much fun it is driving around the BBC trucks :) That is beyonnd cool :) |
Re: 454 vs. 5.3 efi vs. 5.3 carbed
Ever thought of diesel swap?
|
Re: 454 vs. 5.3 efi vs. 5.3 carbed
If your not going to tow heavy loads or hot rod is might as well go with a 5.3/4l60, i would skip the 4.8 nothing against it but they're both so cheap you might as well get a 5.3 for the extra power

Re: 454 vs. 5.3 efi vs. 5.3 carbed
Never thought of a diesel swap. Ill just go with a 5.3/ 4l60 with a tune and exhaust. The power will be roughly the same,but the mpg only puts money in my pocket.Shouldn't have much in it after i sell my motor and trans.........btw Ls swaps look way cooler than bbc IMO. Nothing like a rusted/primered truck with a LS efi motor ;-) , i dont give a damn what year it is.

Re: 454 vs. 5.3 efi vs. 5.3 carbed
A diesel would give you the best mileage out of the truck but the cost up front is higher then a ls swap.A aftermarket company holley i think makes coil pack covers that look like big block valve covers that would mess with people.

I think I found the answer you've been looking for.....

Re: 454 vs. 5.3 efi vs. 5.3 carbed
I like the BBC valve covers on the LS motors. Holleys c10 has en. Its a nice looking motor.
Moose, since u make all the money, you can buy that and ship it to me. It'd be an awesome xmas gift. |
Re: 454 vs. 5.3 efi vs. 5.3 carbed
I hate posting new threads so answer me this guys. If i install the 5.3/4l60e combo using dirty dingo mounts or mounts that are adjustable, would i even have to move my trans member? The th400 and 4l60e are roughly the same length right? Ive looked through some 73-87 builds but not found any that have removed a th400. I know the th350 is shorter.

By a toyota for gas mileage. Put a big block for fun. Just my opinion

Re: 454 vs. 5.3 efi vs. 5.3 carbed
IMHO you should do what would make you happiest. I think if it was me i'd just stick to the fuel injection on a big block w/4l80e. Wait that's what i'm doing anyway. I'm hoping to get fair fuel mileage so I can drive it very often. I think these trucks are cool no matter what they have under the hood.
