The fact that this is something that I do professionally should add a little clout to the argument. If it doesn't, then so be it. However, it's my job to be familiar with bore spacings, valve angles, port dimensions, port volumes, etc. I see similarities between engines and I see where some engine designs are taken from the positive aspects of others.

However, you can bolt an LS head onto a SBF block with the same ease that you can bolt a 351C head to a SBF block. If you can't see the similarities between an LS head and a Cleveland head, I'm not sure how to explain it to you.

The very fact that the changes made to the SBC line of engines (that had in fact been popular since the 50's) going from Gen 1 to the LT1/LT4 and then from the LT to the LS line made them functionally more like a SBF is very hard to dispute.

So, you can add all the little literary intricacies to your paragraphs that you want (crickets chirping) but as you put it, the facts are indeed the facts.

Just so you know, I am a Pontiac fan too.
