I'm not starting anything, and you guys say this yourselves. The problem isn't aftermarket, the problem is getting the engine to respond right to the mods you add. I know the aftermarket for the Series I. I owned a '94, remember? I was going to swap a Series I L67 into it before my dad died, and we ran out of money completely.
When it comes to cheap, easy performance, the Series I doesn't deliver as well as the Series II does. I'm in low 14'* in the Regal with roughly $150 spent. You just (for the most part) can't do it with the Series I.
I don't think it'* a bad motor, and for some reason I have some strange attraction to it, and the cars it came in. I love the '92-95 SSEi'*, and I think they are, by far, the best looking FWD-era Bonneville. I never said it didn't have potential. It does. It has plenty. It'* power just isn't as easily harnessed as the Series II'* is.
Tuning is the biggest issue, especially with the '94-95 and it'* bastardized OBD-"1.5". It'* not the engine'* fault. I think if there would have ever been an OBD-II controlled version of it, we would have seen bigger numbers come out of the Series I L67.

Way too many mods to list.
