its a long block probly needs bearing cause they sat it outside no coil pack or anythang so should i get it for 300$ or walk away

There is a bare block on Ebay for 500, so I would take it if you wanted to build something like it

ok so im guessing i should get it im wanting to build a high compression motor to run on propane for my cherokee
im leaning more towards it being an 07
so what can i actually do with it can i bore it to 5.7 i think some engine builder prefers that when he builds 383s hmmm forgot the name read it in engine masters

what kind of flange is on the carbed intake for the ls motors?

Its an L33 with basically 243 LS6 heads since the 799 early ones.

That's a Trailblazer type 5.3L.

Bo185

Now that i think about it the L33 also did have the 799's as well as 243's. Intake or camshaft would tell you the difference. Both are very nice.

i would certainly figure out if its a GEN III or IV engine. they dont know what its out of?

$300 is good no matter what but it just depends what you're putting it in.
