Would like to put an LS7 into 2004 Tahoe...is this possible?
Would like to put an LS7 into 2004 Tahoe...is this possible? I figured this LS7 specific forum would know the answer to this question. I have seen the complete factory LS7 crate engine offered at $12,999 through the Jeg's catalog.
This crossed my mind when I received literature from Procharger concerning the h.p. increase for a stock 5.3 liter Tahoe; ~400 rear wheel after install. The LS7, while twice the cost would offer more power with piece of mind of new engine reliability.
In addtion, it should break into the 14's

You could have that motor rebuilt with forged stuff plus heads and cam for a lot cheaper than an ls7 and have equal if not more power.. The heads on your engine flow really well when ported, youll see a lot of ls1 guys using 5.3 heads.. and if you really needed the extra power you could just add a nitrous shot and be well above ls7 power

I have looked at katech packages for the LS7 and it out of my budget. So a stock LS7 or another reliable way to increase horsepower will have to be explored. Thanks.

if an engine is built right with quality parts it'll be very reliable I would look at the katech budget 427 short block and then buy ls7 heads and intake. I would thing it could be done for 3k less than buying a ls7 crate. Then all of your stock electronics coulb be used. You are going to need to upgrade to a 4l80e with that much torque. I say buy the budget block and build a mock ls7 minus the dry sump and get a 4l80e to boot for the same price.

And will the 4l65E(?) hold up to the extra power and torque?

From what I understand, it should be a reliable set up. If you know otherwise I would appreciate your input. I started a thread on the forced induction section and was advised to do exhaust mods at a minimun to pull 400 at the wheel. The only engine upgrade to the stock 5.3 I have considered is installing a very small cam. I will however be changing out the stock muffler and replacing it with a straight through design. Any input is appreciated.
you should be able to get 400 whp for a lot less than 13k....how about some AFR's, a TR224 114LSA cam(if thats too big you can go smaller but that is a great DD cam), and a full exhaust + a tune to pull it all together and you would be at or damn near close to 400 rwhp and it would be a very reliable setup.....

My big question is why are you trying to make an SUV a race car?.. dude its not an f body,.. its a grocery getter or a bling mobile man.. Use it to tow your fbody, not race down the track ... how much is this ATI kit guna run you? what about fuel upgrades and tuning .. you can just buy yourself a ls1/lt1 roller for the price honestly.. i duno JUST my 2cents .goodluck

5.3Ls are turds and shouldnt even be in GM trucks. Go to SDPC and check out the complete 6.0L Escalade engines for $3699...im sure you can get them cheaper elswhere too. Not sure how hard the swap would be.

GM should be ashamed for not offering as an option 350+hp 400+tq 10,000 towing when they have the parts on the shelf to do it. Playing second fiddle is bullshit. I wouldnt own my avalanche if it didnt have 4.10s..the 3.73/3.42 aves cant get out of their own way. 2007s better have some **** as an option at least. Why would they even sell them with pitiful 1/2ton towing capacity compared to the competition? Ok Im done ranting...just GM is stupid.

I was under the impression that when you put a supercharger or turbocharger on any stock motor not designed for it, that the motor was on borrowed time.
Doesn't any sort of FI eventually eat away at the stock rings? And if it is suggested to only run 3 or 4 PSI, then you are wasting your money for a very small power gain, IMO.
