pulled the trigger... LQ4/4L80 swap (6.0 vortec)

[hook50]

thanks, very good info. this is part of my homework lol once i seen what your doing i knew i would get some good info outta this. but like you say i am a bit mechanically inclined but far from a mechanic. i want the low end grunt but also want some good top end power as well.

i was really worried that my last post was gonna come off "dick," i didn't mean for it to if it did. was just saying that i wasn't a real good source of info on this kind of thing. i just told them what i wanted to do, and they spec'd out the stuff they thought would get me what i was after. hopefully after it's all said and done i'll get it dyno'd and we'll see what kind of numbers it puts up. unfortunately i won't have a stock baseline to compare it to, so i guess i'll have to just assume stock numbers. but i'm hoping for some good hp/tq. better be for all the $$$ going into it huh. lol

That's going to be one hell of a yukon when you get done with it. Good luck man. Thumbs up.

 

[AtomicHoe094]

yea, cant wait for the numbers and how she handles!!

alright, i have in my possession my newly respringed 243 heads with dual springs and titanium retainers. still waiting on my converter, evidently it's still tied up with ups, but on its way. so as soon as tuesday comes i can start putting my heads on, waiting on my arp bolt lube to make sure i get good torque that i scored, but isn't gonna get here till tuesday. hopefully start the buildup soon boys. stay tuned!

Why would you do all of this and not replace piston/rings?

 

[branndon_b]

well, it started as a budget build, didn't wanna go into the bottom end and kinda turned into one thing leading to another. but it was a low mileage motor, so i'm assuming that the block/pistons were still good. still had crosshatching in the bores, so i'm gonna venture to say it was still in good shape. we'll see how it goes, keeping my fingers crossed at this point.

 

[branndon_b]

one head on, had to leave to go help my dad with some stuff, otherwise i may have gotten both done. gonna throw the other one on tomorrow.

Cool project. I've got a '96 Hoe that could use some 6 liter love. Might be a good excuse to drop the Hoe engine into my '71 Blazer... Wish I had more time and $$$.

Watching this thread. Good luck, Tony

I do the same thing. I figure I'll break her down over time with this same excuse so by the time I do it, it won't be a big deal.

i encourage you to start doing your shopping and trying to find motors in a good price range. the prices can be all over the map. if you find one, go ahead and pull the trigger, get you an engine stand, and nickel and dime it a part at a time until the time comes that you need it. even if it takes you a year or longer to piece together what you want to swap in, so be it. don't get in a rush, but be ready to pounce if you find something in your price range. like anything else, good deals don't last long.

 

[branndon_b]

getting closer boys, shouldn't be too long now.

getting things married up.

another shot

nice a$$.

closer shot of motor lift plates i made with a buddy of mine to pick up the motor and tranny together without having to pull the valley cover. plus i don't really trust those little bitty bolts to lift it all, even though people do it every day. you don't know my bad luck though, i'd be THAT GUY that pulled all the bolts out of the heads. soooo... 3 big bolts in the front and back of the heads, i feel better about that.

another motor plate shot

looking across the top at all 4

 

[branndon_b]

got some stuff done today, buddy came over and we tore into it today. hopefully i'll get the motor and tranny out tomorrow, gonna have to get an earlier start than today, didn't really get rolling until around 2ish this afternoon. stay tuned

 

[AtomicHoe094]
