Mopar purple .528 for a 383?

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.

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.

I’ve never ported an intake before, but maybe the dp4b can be my first. I have room for a 2” spacer maybe with the DP4B, 1” for sure.

I’m gonna get the pig running after the 4 speed swap with the DP4B. Then I’ll do the cam/lifter swap, start with the DP4B again and try the trick flow. If the trick flow isn’t where it is at, I’ll port the DP4B and run it.

I appreciate your input, and I’m not at all opposed to the RPM, I know it’s the best dual plane available for the BBM. I just don’t want to pay full price for it hahaha.
