that 6.2 parts list is a bit vague at best.seeing the 6.5 turbo made 350 pounds torque,to get 600 from a 6.2 will be expensive.

Many 502s were made from tall deck truck blocks, but the 502 was never (and I mean never) installed in any vehicle as a factory option. In fact, the 502 didn't even show up in GMPP's performance catalog until about 15 years ago.

Its OK, you're young. You'll learn.



really guy, what are you old enough to be my dad or something, you're 9yrs older than me WOW!


like I said do some research and you will see that the 502 has been used is various fleet vehicles. I can spend 5 minutes online and find multiple different sites mentioning the GM502 fleet engine, and multiple sites selling replacement parts for it. The link I posted to you came off of here, take a look:

United Muffler - school bus GMC

The link I posted was not for aftermarket exhuast it was for BUS exhaust.

how are you going to explain the 98-up 454-502 CI gas Bluebird CV200 GMC B7 conventional Bus

Ain't got no dog in this fight- but 87Z's right on the BBC 502. Moving on...

littleredridingwood, the 402 is a better choice than the SBC 350. But displacement is what you need. If you're on a budget, chances are that will mean no turbochargers or superchargers. The diesel option is all well and good- but that's going to require a lot of finnessing to get the kind of power that a 454-up BBC will get you NA and will be an easier to build option IMO.

Unfortunately, finding a good 454 core is getting harder every day and the cost is rising as well. I hear how there are good $200 454 cores- until you go to pin one down, then just like $5.00 Q-jet cores- suddenly they are nowhere to be found.

The best deal I have seen recently was on a Demon reman 454 engine in a CC article, Cheap Big-Block Chevy Engine Build. Who knows what the current pricing is like, but you could easily find out.

Searching the machine shops in your area might turn up something that was left behind, then there's craigs and eBay, etc. But you already know all that.

That is what I started out saying in the first place. If you are willing to scower junkyards you should be able to find a factory 454, and possibley a fleet 502 if you get really lucky. I would bring a jump box and a compression tester, not make sure the cylinders are okay but to make sure there are no major issues. tons of 80's and 90's GM work trucks, utility trucks, tow trucks, you can find them in lots of medium duty chassised Chevrolet Kodiak/GMC Topkick, B6, B7 fleet vehicles. If you where to look through these you could use the 7.0L 427T block as well.

with one of these engines you could easily just buy a plain jane rebuilder kit (although I'm not a fan of these), splurge and buy a set of aftermarket iron heads (used or new) go with a mild cam, and it would be easy to make a minimum of 400-425hp and 550-600tq all day long.
