408 Stroker

70, i think you have it backwards... The 3310 750, when tested wet, is about 680cfm. The Avengers/HP Holleys, and Demons are wet flowed. The 870s I run are great. They need about 3 sizes more primary jet but that's it. The latest one was idling nicely at 800rpm last night with a hyd roller cam that's 238/[email protected].
