Hey family just checking to get some info on who’s running Trickflow 170 heads on 302 stock bottom end. What’s the biggest cam you’ll running with 1.6 rockers or 1.7 rockers? Looking to put an cam on my stock bottom end. I have a cam on the shelf it’s a xe270hr cam 512/512 lift 218/224 duration with 1.7 rockers.

I ran xe 264 hr-14 (same lift .512 less 2 deg duration) on stock 86 bottom end with no issues with TW170 and 1.6 rockers, also tried 1.7 since I had them and they worked but didnt gain anything so I went back to 1.6. I would still check PTV clearance but should clear no problem

I've got TW170 heads, 1.6 rockers and a Comp 35-302-8 cam which is a 220/224 @ .050 .512/.533 on a zero decked block with stock style replacement forged pistons. I checked the PTV and was a few thousandths below the recommended clearance on the intake side, so I ended up retarding the cam 4 degrees to get within spec.
