I made 280 HP and 380 TQ with the stock ported base, a ZZ4 cam, L98 Corvette heads, and SLP 1 5/8" headers. I ran a best of 13.25 @ 107.18.

Now I've got more mods and struggling to find traction.

13.81@98.98mph with stock intake, runners and plenum on a L98. Everything was ported and gasket matched. I also had some good suspension mods, good enough for a 1.96 60ft.
