IMO all are on small side. 5.13 gear with 29" tire I would figure you will be spinning it pretty good and all listed are not going to be high rpm producers. I would be looking at something in mid 270's to 280 degree range. But hey I have been wrong before. America home of free. Brought to you by 2nd amendment. | |||

Other than for a cost saving, why a flat tappet cam? | |||

Why not? Cost saving is part of it. | |||

WHo picked those lobes,, no reason to have more ex lift than intake. LS 104 to 106, 256-260 and 262 to 266 duration. Install 2 to 4 degrees advanced. | |||

Who picked the lobes? Those are from 7 different cam sources including custom grinders. | |||
