Death Of A Lt1...
****..I found one in a Junkyard about a Month ago..the guy there was like "there's an Engine over here..it's Aluminum and it says 5.7 on it..I've never seen that before.."
Sure as **** it was a LS1. He only wanted $400 for it..
Looking at it closely it had a Spun Rod, and had been smashed up a little bit..it fell off of a Fork Lift. I tore some parts off of it that I needed at the Time and left it there..

Yea, we will see, i am thinking ither find a 5.3 out of a 99+ truck and use the LS1 induction and harness, or use my 383 with a crank trigger id i cannot get a distributor to work as i want, i got time, i am going to get my 89 up again first.

stock rods pistons 6.0 50$ (.030 over pistons are 180$)
ls1 intake 50$
75mm tb 50$
26lb. inj with fuel rail 100$
ls1 stand alone engine managemnt harness with obd2 port/pcm 450-500$
maf 50$
ls1 to sbc 3rd gen mounts 100$
crossmembr for th350/400 with tq arm mount 150$
6.0 flexplate with spacer (th350/400 bolt pattern) 100$
even 700r4 is adaptable with this stock flexplate
LS heads-from 200$ to 500$ for quality 241 0r 243 casting.
02-03 z06 ls6 cam 100-150$
ls6 springs 70$
LS coil packs 100$
6.0 truck exhaust manifolds 50-75$
even with these parts, which are mostly all stock from various ls vehicles.
if u go with the ls6 intake/heads and cam in a 370ci 6.0 motor its basically a
400-425hp with stock manifolds.
whats holding u back, ive have my own version of this combo for my third gen and building another for a friend.
of course ther will be other misc. parts but this basically covers the core of the system. a great entry level swap, with lots of potential, tunabilty, powerful ignition,
a 3.73 gear with 3500 stall, th350 trans will make your rs into a nicer street screamer, and with a 150 n20 shot

Well, if i can figure out how to get a signal to the PCM from a traditional mount distributor i will go that route, i have been doing a bunch of research and i got one guy that just needs to tell me how he did his.

it is an example of how a budget strong ls motor can be put together for swaps. the ls aftermarket premium seems to have gone away now,
and imo and exp. the prices have really dropped.
just giving an example of what has worked for me inthe past.

weight,
rods, bearings, pins, rings, are the same weight but must account for new heavier piston weight, for 5.3 crank or just use ls6/ls1 crank in place of
5.3 crank. i have done the machine work to this block before, but imo
might as well pay the same to have a 6.0 block and have a 4.03 bore as oppossed to a 3.905 bore. machine work will be of equal price if not more for the 5.3-5.7 bore, since it requires more material to be removed , over .115
of material removed with final .010 hone, or so depending on preparation and
cylinder finish

he uses the tpi intake for blueprint, and location of dist in lt intake,
uses 95-99 vortec truck crab type dist cap with msd replacemnt, uses lt coil
for ignition, and he has a harness, that connects, the dist to run properly, his own car is running with a t76 355ci lt4 head motor, uses fmu for fuel, and ed wright tune, along with 42lb. svo injectors, car makes over 550rwhp on 10psi
he dont post on here much, works as a machinist for oil industry fittings.
has done 2 conversions for friends of mine.

Well, i was just going to use a full TPI setup with the LT1 intake if i cannot manage to mount a rear mount optical setup, i have found a couple of folks that have done it, but getting them to fab one up or tell me where i can get one is kina hard.

So you would build a motor with out balancing it?
If you alreay had a running 5.3 and wanted more there is not much wrong with going that way. Buying a 6.0 block is easy to do yes. I was just tossing it out there as an Option I have seen work
