Where would you clock this cam?

Advance? Retard? Or straight up? And reasoning why.

383 + .06" BBM 394ci. stock rod length and crank throw. 11:1 mechanical compression. HP Ultra 750 E-85, 3600 lbs. Slick Shift 4-speed. 4.88. 31" tire.
Trick Flow top end w/Manley RAS, Comp, and PAC.
It should trap at 6600 @125 if it can make the juice.
Bottom end is sound with Milodon oiling, Manley Pro Series I-beams, Ross custom, and Total Seal. Scraper and tray. So...it should stay together when twisted tight.

Camshaft: Mechanical flat tappet. 236@.05" intake, 244@.05" Exhaust. 114 LSA. 297/334 advertised.
Straight-up +-.5 degree.
IO 42 btdc, IC 75 abdc @.006".
IO 5 btdc, IC 51 abdc @.05"

EO 99 bbdc, EC 55 atdc @.006"
EO 58 bbdc, EC 6atdc @.05"

Cam grinder recommends straight up. others say +4. I've even heard -2 degrees.
Effective compression ratio straight-up 8.6:1.
So, where would you close this intake valve?

OK, have fun.

You're missing 2 degrees @.050, unless you meant 236 @.050.

Checked it three more times. 236@.05" Fixed. Thanks.

114 LSA angle with a 4 speed I would install it at 110 or maybe even 108 ILC, that motor will not be a torque monster with that cam

Split overlap would require that you advance it 6 degrees which might be too much. I'd probably start with 4 degrees advanced. Why does the cam grinder think it should be straight up? The usual recommendation is 4 degrees advanced. 114 is a wide lobe center for that application. I can't tell if you are building a bracket car or a street car. The gear ratio seems like a bracket car but that lobe center seems like a street car or an EFI car.

Both Street and strip. It's got OD for the highway which equates to a 3.56 gear. 2500 rpm at 65mph.
It's a mute point now. I just measured PV. In at 113.5 (timing gear set is cut 1/2 degree off) leaves me with .062" on the intake and .085" on the exhaust with zero lash. So there's no advancing this cam without making changes.

I'll move it forward 2 degrees tomorrow and see what it measures, but it'll probably stay in at 114.

The cam grinder is correct in that it goes in straight up. Believe it or not, moving the IVC and few degrees is less important that what happens at overlap when you move the cam around, and advancing that cam changes what’s happening at overlap the wrong way.

I’m not sure what the LSA is 114 but that’s pretty wide IMO.
