Ok looking to swap motors as about everyone knows. I know a ls1 is obviously lighter then the truck motors. Yet it doesnt have the cubes of a 6.0. If I were to list a ls1 as something I would throw in how many miles would be the cut off point for a good motor? Any major drawbacks to a ls1 over a 6.0?
As always, the lower the mileage the better, thats all. Great motor, with great potential to make more power. 6.0 has slight more torque is all. Wouldn't hesitate to jump on a fair LS1 deal. I did.:)
I wouldn't loose sleep over the weight difference between the two unless your truck is a gutted out full on dragster. It's something close to a 100lb difference only. If I had to choose my golden rule is "No replacement for displacement"
No replacement for spending almost a full grand over a 5.7 for 16ish cubes either... So far cheapest deal I found was 1700 for a lq9 with 50k...
IIRC....Lq4/4l80e + harness and computer for 1800 in for sale section...

Really wanting a lq9. Something with higher compression.
Good deal...i'd be all over this if i didnt already have this setup! Throw some 243's on the LQ4 and bam you have LQ9 CR if not a little moreQuote:

yeah get it right in the same area...the 317's are a 72cc head and the 243's are a 66cc i believe so that right there will bring a 9.4 up to the 10.0 of the LQ9, or at least very very close to it.Quote:

LQ4 with 243 heads is 10.4 cr
LQ9 with 243 heads is 10.9

using a LQ4 you get away with a slighty dish so it has some room for PTV over teh LQ9. However you got a mill heads just to get the compression up so there goes your PTV
not like you loose a lot...he can still run a plenty big cam, specially if he's going boost on this stock motor he dont wanna go to extreme...and he wont have the PTV issueQuote:

Probably more HP than a lq4. Less than a lq9... The higher cr of the 5.7 will help it out perform a lq4 I would think. Only reason I am considering a lq4 would be to run l92 heads later on :chevy:
sounds like a deal to me. i can get the ls1 for 850 and cant find a 6.0 under 1200

keep looking and you will find one. mine has 160k on it, but it wont be running until later this year so i got time to get it built how i want it before i NEED it to run.
