will stock upper mount to any aftermarket lowers?

The Holley Systemax I intake manifold was the only one that would bolt to a stock upper. It was a slow seller and got discontinued last year...you might find one used or on ebay. The Systemax upper and lower kit that most of the 5.0 guys are familiar with is really the Systemax II.

Oh yeah, the Comp Power Box is still around but you'll need a lot of RPM to take advantage of it

If you're on a budget, get a Cobra manifold off ebay...there's a reason neither of these manifolds sold well. :rolleyes:

Hmm not that im aware of I know comp makes a upper that mounts to the stock lower but never heard of a upper that mounts to an aftermarket lower.

I forget about the systemax 1 that was before my time I actually never saw that one only saw the second version and that doesn't mount
