If it is a 5.3 then it is a swap, GM did not put a 5.3 in a Camaro. b4c car means it was a 5.7 LS1. The 5.3 is a bolt replacement and common. Very cost effective vs finding a Ls1 motor with low miles. The 6.0 will also bolt in and depending on which one you get it can be a nice upgrade form the original 5.7.

 

yes i see the difference though they did not say was a z28 .guess there popular builds ,i may think about it one day ,with the right car a very clean one though,.an they say coninsidence does not happen that offten probley .more then one .may think,yes it sounds like there could be problems ,i am not sure i would bye one unless i knew who did it ,i guess seeing .driveing it would help,i had seen.this guy selling a .95 on ebay for 7000.00 make offer with 190.000 miles i had to ask him . why so much ,then he told .me it was where he lived in SC that the car with no engine was worth 2500.00 for a rolller ,so i been doing an east coast search ,i found a 94 with 91.000 for $4000.00 in SC,so the guy does not know what he is talking about full of bull ,theres only certain places they cost more ,an so far only.place i found was LA..otherwise there out there 60.000 miles .$5000.00 i seen atleast 10 or more on .east coast floirida to,how ironic ,i would go for the 6.0 ,sleeper .its funny how i get the trucks that actually think they can beat you in a race ,but i dont race so.foolish unless . the truck has some big . hp like farm truck ehhehe,an i am sure in winter even better deals are found
