Re: 454 engines

Did all 4 bolt blocks for 454 engines, get the oil -cooler provisions in it? Are was that only for the LS-6 engines in corvettes . Could it be a true 4 bolt block yet not be tapped for the oil cooler?

Did all 4 bolt blocks receive the machining for the oil cooler provisions? This I do not know because I have not seen all of them. However, I can say that typically they did have those provisions and I have never noted a 4 bolt block that didn't have them. But, that does not mean that none were ever manufactured.
