vortec 454 external oil lines(want to delete)

[bucket]

Driver in a truck I would keep them. That being said I run a gen6 block in my race car with them plugged off. No oiling problems for the 5 yrs I been running it

A gen 6 block from a truck, or a gen 6 block from GM performance parts?

First was a 98 gen6 vortec 454 that was rebuild to a 489 and was in my dually. Current engine in racecar is a gen 6 502 block. Both production blocks. 489 still running in another truck after 5 yrs with them plugged off.
