Will be pulling the 350 currently in th 67 and looking to replace with new one. Top of the list right now is one from Pace Performance. Complete package including Holley Sniper set up. Main difference is the Pace vs GM Performance is a cam change and only 1 year warranty. Would appreciate you "Engine" gurus opinion. I value your expertise as I have read many of your responses on engines and complementary components. Thanks. Link below.
