February 8, 20187 yr If my rig didn't come with the 6.2 I'd be running one. Hard to say no to the extra displacement, but I am limited in HP right now by the block. Any wee gains and I'll push water.

That being said at a certain power and weight threshold you have no choice. How "built" of a motor are you planning? I am going to say mild just a street toy..Honestly I was going to start with just a basic stock 5.3 and go from there..I realize there is not really a huge horse power difference in the 4.3 v6 and the 5.3 or 5.7..But they dont seem to be alot out there for the v6 without pouring a fortune in it..And from what I researched I can just add wires to the existing harness for the v8 spyder..And I can get a LS swap kit exactly for it for like $700 or so..So to make a long story short I would like to just do a drop in out of a Silverado,Suburban,ect..And mildly beef her up a bit on a budget..lol

Speaking of...I dont know if you seen the newer movie Chips but that 2016 Impala SS at the begining was bad ass! They have the 5.3 as well I do belive..And I assume it is a rear wheel drive also.

They have the 5.3 as well I do belive..And I assume it is a rear wheel drive also. The Impala SS is no more and hasn't been for several years now. The car in the CHiPs movie was just a Chevy SS. It is RWD and actually just recently ceased production. It did not sell well. Actually, it was nearly impossible to sell. The Impalas are still FWD, and the V8 cars with the 5.3 used the LS4 and someone indicated on the previous page. It is not like the 5.3 Vortec. The block, intake, and several other things are bespoke to it for FWD use. I think they use a weird starter or mount or something.

February 8, 20187 yr 1 hour ago, ///M5 said: Seen some buys for <$100 if you pull it yourself. All for a motor that with a turbo can easily hit 600+ for nearly no dough. I LOL when I see you type about budget builds. $5K is not a budget build for me.

February 8, 20187 yr Bigger blocks from GM will wake up with the heartbeat easier, but if you brew your own the charger option is significantly more expensive than going with a turbo.

You're not running 10s on $500. I'll provide you $500 and a car. Let me know when you have it running 10s. Granted, you can find an engine and a turbo for $500, but that's it.

Much cheaper to build in the GM domain unless you are targeting over 800hp. An Ecotec can easily drive a T4. Hell that little Chinese 3 cylinder they make could spin one given the proper turbine and header. You know there's no replacement for displacement. Use as large as possible. You make more power on less boost and break less stuff.

Change to a T6 and the expense and different story.
February 8, 20187 yr For myself since I can't fab shit, I just bought a damn kit. $5k is about right...but hard to get much over 12lbs for less with a super charger and not using used parts.

Ahh..I didn't notice that when I looked it up..I assumed it was a Impala SS.....I seen that some came with the 6.2 didn't they? And why didn't they sale to high priced? They seemed pretty nice but I never seen one in person either..What was the deal with them?

It's application dependent. We can't just say T4 or T5 or T6, or anything for that matter. We don't have any information on turbine or compressor mapping, cam specs, mounting, etc. We can all do dyno tests and make the results read any way we want. I'm going to assume here that you've seen some where they did basically a swap of a kit from a 4.8 to 5.3 and did pulls on each. All that indicates is the turbine and compressor are not proper for the application (5.3), or was best suited for the 4.8 application.

Honestly, I think they were overpriced for what they were. $10K cheaper and they'd have sold like hot cakes. Just my opinion. Think of it as the blue collar CTS-V. They're ugly, but the performance can not be denied. Of course when you look at it that way, it makes you wonder how Lincoln sells any of their "dressed up" Fords. It must be all Matthew McConaughey. Yes, that's it.

February 8, 20187 yr Just now, mikel7829 said: Would it be easier to just do a 5.7 vortec from around the same year? I can't tell you what is easy for you. I don't know your skill level, will power, budget, etc. . . People often get ideas and start builds and they stall when they realize easy is not as easy in reality. Ask me about my F150 that's been sitting since 2010 needing a simple head gasket that turned into a broken valve that turned into an engine swap that turned into thousands of dollars in new parts, that turned into a rusted out cab that was previously rust free, but spending several years in the same spot on dirt exposed to weather and oh yeah, let's not forget work and being a parent override everything else in life then you get sick and your parents are getting older and. . . .
