Re: 427 LS engine in Peoria, IL
You're replacing the engine in your red Firebird? Already?
BTW, the guy I bought my car from was in Oreana. Total scumbag - DO NOT do business with one Michael P. Sleeth or any of his associates.
Also, if you'd like to track him down and break his legs for me, I'd be much obliged.

No, I didn't. Thanks for the tip.
I'm really out of touch with where people have gone and where to go to sell car parts. You're right about not being able to sell anymore on the forums.
