TBI boy takin the plunge...

Well Xmas came early for me today.....I have been searchin for a couple months for a 5.3 to swap into my 91 RCSB and today I found the winner....I hope. It is an L59 with 97k miles out of a 2002 Tahoe. It is complete with all accessories, harness, and ECM. Comes with everything except the TAC module/pedal. Snagged it for only $412! Maybe its just me but I think thats a good deal....I go pick it up Monday. Pics are kinda crappy but let me know what you think!

Im not real crazy about it being Flex fuel or DBW but I think I can deal with it....
It being flex fuel should not make any difference to me correct?
Now I need a transmission....Can anyone tell me what years 4L60Es will bolt right up to this motor with no adapter plates or modifications?

Good deal, where did you buy it from!

It is an auto recycler called LKQ. LKQonline.com This seemed to be a heck of a deal since most of the engines they sell at this price are not complete pullouts, have higher mileage, and do not include accessories. I could not pass this up especially since it happened to be located about 45 mins away. The only reason I can think of that made them sell this package so cheap is because it is flex fuel. I hope this flex fuel doesn't give me any troubles.

Awesome and it being only 45 mins away makes picking it up easy. I don't think the flex fuel will be hard to overcome.

Does anyone know what 4l60Es will bolt up to this with no modification?

I would assume that a 4l60e cam WITH the 5.3. But you should not have any problems with that. You could put a 4l80e, th400, powerglide, ect.

Ya i know it came with a 4l60e I just dont want to get a 4l60e from a different year and then have to swap flexplates or add adapters and stuff like that. So I was just wondering which years are the same. 99-06 all the same?

To my knowledge if you get the same year, or a little newer, you should be fine. I dont know if the 5.3 of the 99-00 year had the long crank snout like the 6.0 did. But I would assume so.

99+ 60e that came behing a 4.8/5.3 will be fine, flex fuel won't hurt, in fact you get bigger injectors and if it has the same square fuel rails the newer e85 motors have they flow about as good as any aftermarket rail

Sweet. Ya, I knew about the bigger injectors which is good except I probably wont need them since all I plan to do is headers and a mild (TR220) cam. And I think it has round fuel rails but Ill check later.

99-07 classic 60E's are the exact same. the 07-08NNBS trannys are the same also minus some inside parts.
flex fuel is good like said..bigger injector which means better cam choice ;)
i wish i would have gotten a steal like that on my motor :( damn good deal man. change the tb to a dbc from a 99-02 intake or find you one already p&p. if you wanna upgrade then you could snag a NNBS intake an a dbc 90mm tb an have a strong top end

ya I'm not sure if I'm gonna change the TB or not. There are pros and cons to both. With dbc I have better response and don't have to fiddle with changing the damn pedal. But with dbw cruise control will be just a couple wire hookup and I won't have to mess with findin a tb cable that works.

Picked up the motor today. It looks good except the water pump and ps pump pulleys are bad/warped/bent. It came with everything except the TAC module/pedal assy. They said they would sell me the pedal out of the donor vehicle for $100. I noticed the head casting is 862.....is that good, bad, or neither?

Thats normal 5.3 head. 9.5 to 1 compression

Alright. Which stock head casting is desirable?
12-28-2009, 06:33 PM

243 and 799 are the best flowing but the 862s are good heads too.

thanks.

Does anyone know if that's a good price for the tac module?
Or should I just switch to dbc and why?

Every site I have read points to DBW being the better choice. Most choose DBC for ease of install. TPIS did a dyno on a stock 90mm DBW vs a stock 90mm DBC and the DBW flowed better and made a little more power. If you have a DBW harness, you should run DBW.

Easier to do cruise control too.

Thanks. That makes a lot of sense and is what I wanted to hear. I didn't know that dbw was better for performance. Seems like if it was good for a few more horses than more people would run dbw.

No problem man. If it were easier to install a DBW, thats what I would have done. Not to mention you can get a 90mm dbw throttle body pretty cheap. Compared to a 90mm DBC throttle body.
