Was that a shelf cam or a custom grind? Also what duration?

small light cat really doesn't apply to us resin bucket vee's when it comes to spinning a prop.

Question.

Seems like the Victor JR gets specd on all these builds. Also seems like, on almost every one of them, adding spacers show gains.

With that being said, why is the "super victor" intake ruled out as an option?

I know we made several pulls and a 1 inch Spacer was what it liked on my Vic Jr. We tried none, stacking, etc and found nothing but losses. I can see what you're saying though as the Victor has a larger 4500 flange. Could run their spacer/adapter to go to a 4150 anyway


I have the pulls labeled when we tried diff spacers. When I get home I'll see about posting up the differences

I would use a Dominator intake and put a 4150 carb on it.
