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.

In a stock 346???

 

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.

Seems way too big.

 

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

Attached is a list of mods that are being installed on the car. Please post your thoughts. We plan on spinning the motor to 7200K.

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
