What heads are you running? Just the stock L98s?

293hp@5000
351tq@3500
160cc ports, 9.1:1comp is what I get.

Stick with the 350 man. All else being the same, 23 more cubes means more power and torque across the board...

Performance Trends show 395 ft.lbs. at 4000, and 350 at 5200.

Throw on the Vortec's and add about .9 compression and it goes to 410 ft.lbs at 4000 and 375 at 5400.
