Well, grandpa's gone and done it again. He bought entirely too many of Gavril's flagship 502 CUI crate engine, the ZZ502/580 Performance Pack. Granted, he probably won't quite see that 580 lb/ft since grandma said he has to put exhaust on whatever he puts them into, but that's fine. He can still floor it and roast the tires to oblivion, which is all he wanted. And if he ever feels the need for more, Gavril always has the ZZ502/720 pack which he could buy...
'ZZ502/580' carbs, stock exhaust, tubular headers
'ZZ502/580' carbs, no exhaust, tubular headers
'ZZ502/720' carbs, stock exhaust, tubular headers
'ZZ502/720' carbs, no exhaust, tubular headers
Gavril 502 CUI "ZZ502/580" Engine 2.0.1
Grandpa put the big block crate engine in all of the famly cars
