    Darko had some H2 take out 6.0 motors at Pacific Motors last time I looked, but he is getting top dollar for them. Still, might be worth checking.

    If you plan to rebuild here's a iron 5.3 for $200. Set of $100 gen 4 rods and fresh bearings and she's a ready to rock.

    Punch those 5.3 iron blocks out a bit and you can use 5.7 LS1 parts.

    A small update on the LT1 Opti....

    I got the second AIP Opti sensor, installed it and bench tested it on the O-scope. I could see the high res and low res signal. I put the distributor back in the car, cranks but wont start. No spark from the coil.

    I am going to go back through the factor service manual diag process a 5th time and make sure I did not miss anything. The trouble tree keeps pointing to a failed distributor or distributor connection (the connection(s) to the distributor are good).

    I will be reassessing the car at some point this weekend/early next week. I'll post the findings. The LS conversion is starting to look way more appealing.

    I don't know too much about the LSs as far as choosing this vs that. Other than displacement, how is the 5.7 different from the rest of the LSs?

    If you were going to swap an LS into a C4 Vette, what engine would you go with and why?

    Just depends what your goals are. 4.8/5.3/5.7L are all "small bore", meaning that you'll have to use the older cathedral port heads. 243/799 heads would probably be your best bet there. These combos could make 300-450hp pretty easily and reliably.

    6.0/6.2L are "big bore" and will allow you to use LS3, LSA, LS9 big square port heads that flow really well.

    Iron block is about 80lbs heavier, but can handle big power. Think 1000+ hp easy. Aluminum blocks are lighter and proven to 1000hp.

    Best budget set up? Iron block 6.0L with a mild cam, ls3 heads and intake. 500hp pretty easy.
