502 casting
I have a guy who has a 502 for sale and he will be giving me the casting numbers tomorrow. He was not sure but said he thought they were all the same. Are they? What do I look for? Thanks in advance for info.

When you get the casting numbers, google "Big block Chevy casting numbers", there will be several sites that will come up with the casting numbers-it will show the year made, bore, stroke etc. It really is simple to look these up-once you have the numbers. Once you have the casting numbers you can determine EXACTLY what you have-the year Generation IV, V, VI etc. Same goes fot the heads. Hope this helps.

The 454 is a 4.25" bore (roughly) the 502 is 4.5" bore (roughly), so even a simple measurement across the pistons on the short block would let you know.

Thanks fastshafts
I will ask the guy to make dam sure its a 502 before I pull the trigger. I cant measure anything as the block is 600 miles away. I did not know there is a big 8.2 on the side. Which side would it be on? What are the differences in the generation 4 5 6 ?

Thanks mrfixall.
I will ask for pics from the guy. he will be giving me a shipping quote in the morning. I will get them to you as soon as I get them. Thanks for your help on this.
So if I want a full roller engine I want the mark IV or VI as it is set up for it. If its a V and I want roller I need to add that lifter girdle thing that adds mass and is not ideal. Am I understanding that right?

with the correct lifter you can make any big block a roller cam set up..the gen VI is limited to .575 lift with the factory lifters,,if you go higher then .575 then you will loose oil pressure and the lifters will get noisy and in come cases you will loose power over 5k rpms..
