I need a new block for my 97 Z, and my heads are shot too. So i figured a long block is the way to go. I found this long block for a decent price but what do you guys think?

any motor from a auto parts store or on line warehouse is most likely gonna be crap!
if you get a short or long block it needs to come from a non mass production company the ones u get from auto parts places some times have mismatched heads and some times even mismatched main caps with out line honing it and thats no bueno there are a lot of those motors that crap out very quickly

 

Try e-bay, there are still a few factory new gm units to be found for a good price. http://cgi.ebay.com/ebaymotors/Chevy...item4cec36a608

 

That's an iron-headed LT1 in the ebay link....

 

Does it really have to be new? You can find perfectly good LT1s a lot easier for less than a grand and spend a few hundred just freshening it up.

 

yea its a iron head but its a brand new FACTORY long block and you could run the factory heads which do out flow the stock alum ones or get some nice alum heads and just swap um over
