Wondering what you guys thoughts on swapping in an ls7 vs a Maggie for a daily driver. I'm really looking for around 550 rear wheel dependable hp. Not wanting to run meth on a Maggie to keep temps down. I know an ls7 swap will be quite a bit more money.

I'd love an LS7 in mine but the cost vs going with the Maggie would keep me from doing it. I think you could safely make 550 with the SC.

Maggie all day! Thst LS7 swap will be pricey. Plus u can make 575 all day with a Maggie. with the correct set up.
A LS7 will need heads/cam intake to even get anything close to 550.

I "daily" mine with a Maggie, not very far, and it's great. Haven't had any heat issues, just worse gas mileage :) Going to be cheaper than the LS7 and you have several options on your setup and tune to make the power you want.

My 1900 puts down almost 600, no meth and temps are fine. I've got almost 12k miles on my build with no issues. *knock on wood*

A LS7 is going to need to be pretty damn radical to make numbers like that NA in a TBSS!

Go Blower and enjoy.

There IS an LS7 427 putting down 540awhp which happens to be the highest "known" N/A awhp out there. It is "mildly" built and using meth by a well respected forum builder. Just depends on what you're after and what your budget will allow. 550whp CAN be had while still N/A and "maybe" by something even less than 427ci. Jus sayin.

Edit: Don't get hung up on hp numbers on a dyno. Making good power and the ability to put it down will win out.... It's NOT just about your hp numbers.

Option 3 : tvs with built motor, if you really plan to drive the truck and not worry about it.

Everyone with a tvs or a blower ends up going forged sooner or later - some by choice and some due to carnage

All motor ls7 is always a lot less headache and better reliability, but your hp goal is on the high side.

Neither!!!

Is it a 2wd rig?
If so, FMT (front mount turbo) all the way baby!

Or get a procharger...P1-SC-1 or a D1SC...
The intercooler is more efficient with the procharger so IAT's and detonation are not as big of an issue, power comes on linearly with a centrifugal unit as opposed to immediately with a roots/twin screw supercharger, andwith a centrifugal the power keeps gaining as RPM's increase, whereas a Maggie will plateau and even choke out

They all have pros and cons, I like centrifugal chargers myself. Typically, you will make more top end horsepower "safely" with a turbo or procharger than you can with a blower or NOs, and centrifugal chargers tend to be easier on the chassis and stock engine than a Maggie is

Just my .02

Yeah forced induction would be the easiest route. A stock ls7 being 505 at the fly wheel. I guess asking for 550 rear wheel is asking a lot for it to be dependable. I drive at least 60 miles a day. Just a bad experience with a procharger on my mystic cobra. It's a 2wd

I would love a front mount turbo, but realistically I would need to get another vehicle to drive while it was down.

Maybe not?
There was a member/vendor working on a FMT header/collector system, crossover and all...

If you got the parts together, turbo, intercooler, boots, pipe and headers...it could be as quick as a weekend project, depending how mechanically inclined and motivated you are...

:)

You're 2 wheel drive huh, NOTHING would change my mind of going turbo if I had a 2wd tbss

Yeah if there was a readally available pipeing kit for a tbss fmt I would go that route for sure. A 76mm turbo I think would meet my hp goal pretty easy.
