So I broke the crankshaft in my LBZ, and I am trying to decide how to get back on the road (unfortunately a full So Cal Stage 1 engine isn't in my price range right now). Thus, as I see it, I have 3 options:
1. Try to rebuild the motor (assuming the there isn't too much damage to the block. Still would need to find LB7 pistons, and take the necessary time in the machine shop.
2. Purchase a new long block from GM for $7700, and then just put all of my stuff back on a new engine).
3. Purchase a used block. Cobb has one for sale at $5300 (plus $300-$400 for shipping. It has about 80,000 total miles but was rebuilt after the first 20,000 by All Seasons. When rebuilt, the LBZ block received LB7 pistons, and LBZ rods, and the engine was balanced. Cobb claims there was a huge difference regarding how much smoother the rebuilt engine ran as compare d to the was than stock.
I'm probably putting out about 600 horsepower and 60 psi max boost with the mild triples i have from EPR. You can see my other mods in my signature, and I don't really have any plans to try to make more power. As such, what do you guys think I should do?
Do I (1) go with the more expensive, but brand new, stock motor and hope it provides at least another 120,000 miles because everything is new?
Do I (2) go with the semi-rebuilt motor that may hold up better to my mild triple turbo set up despite having 50,000 miles on it?
Or, do I (3) try to rebuild my motor, and waste the time and effort looking into every part? (Is there any chance of saving any significant money doing this?)
Thanks for any and all opinions. I appreciate your time.
