HEY MEN!! Be careful out there it is a jungle with these ''buyers and sellers''.I called a guy about a 454 engine on craigslist.I ask him for the block casting numbers along with the head numbers.Well you thought I was putting this guy through alot of trouble.When he came back with numbers,this hi performance motor was a truck motor.When I mentioned the web page that I got the referance numbers from,this guy got all arrogant with me and told me I insulted him .If I didnot do my homework,I WOULD HAVE PAID 7K for a piece of crap truck motor.Watch your money fellas!!!FISHMANJOE
