Opinion: Main Support or Windage Tray

[Yard Dawg]

Could use some advice on whether to use a main support or a windage tray.

I was planning to use both, but they won't fit with the Canton 7qt Road Race pan.

It's a SBF 347 (N/A for now) and it'll be going back into my daily driver.
(We pulled the motor to fix a seperate issue)

I was previously running just the windage tray but wanted to add the support while it was apart in order to strengthen the stock block.
I am also adding a "valley girdle" as well in the event that I add a mild blower at a later date.

It will see some open tracks and a few autox events.

Would appreciate your input/opinions.

Thanks in advance,
Steve
