Mopar purple .528 for a 383?

Which intake is wrong, the DP4B or the trick flow? The dp4b came up really close to the rpm in the manifold shootout. The trick flow is on hand and will go on for ***** and giggles purposes. If it’s a dog it will go back on the shelf. Unless someone wants to trade me a tunnel ram for it.

OH! I was making a red to the TF single plane. The older DP4B would be my choice. If you’re capable, port match it as deep as possible. That’ll help a bit. Also, I do belief a combo spacer up top would be another small helping hand. If it fits under the hood.

The 3.91s and four speed will allow you to run any intake you want.
But good points were raised about c.r. You really don't know what pistons are in it aft3r all this time.
( I think I have used five different single plane intakes vs two, whoops, one dual plane. But my cars have 3.91s and 4.10s)

I’m still with a rpm on this. The gear ratios listed will certain wake up the car. The nice thing about those gears and the single plane is once it starts to rpm, it’s gonna feel really good upstairs.
