Debating between these 2 Howards Hydraulic flat tappet cams for a mostly street cruiser with some strip action (idle quality is not a concern fyi). Engine is a 70's 360 with the following:
- Ball hone rebuild on the bottom end (stock bottom end)
- Stock heads with .028" thin head gaskets (possible milling the heads for compression if in the budget) and speedmaster adjustable rockers
- Air gap intake
- Holley 780CFM carb
- Hooker 1-5/8 headers
- 3700lb car, 3000-3500 converter with manual valvebody
Which cam would be the better choice? Which would create more vacuum? Would either be okay with stock pushrods and rockers, or are the adjustable rockers a good idea on this? I've never done a hydraulic flat tappet build before, only roller and solid stuff. Any one brand of lifters better than another?
