Default New Cam

I'm in the process of building a bracket car. I'm installing a custom cam 247/251 .623 113+3 along with 215cc Trickflow heads. Your feedback would be appreciated.

Car is a NA 346, 4500 stall, Turbo 400, S60 with 4.11s/spool, and will weigh 3100 with me in the car. Car is a full time race car and will never see the street.

The combination was designed by Ron at Vengance Racing. We are looking for low 10's.

It does seem a little large (mainly on the intake side), but those TFS heads flow great and the guys over @ Vengeance have put together some nice combinations, so I would trust him.
Here's some other well-performing "big" cams for reference:
240/244 .605/.596 112 lsa- Vindicator
242/248 .608/.612 110 lsa- TRex
239/251 .570/.570 106 lsa- GM Cup Cam
Your cam isn't much bigger than either of these

Please post your reasons for why you believe this cam is too big for the application. I would appreciate your feedback. Please note, I'm a novice in the technical application of cam specifications
