As it was just explained to me, the new rule applies to those who have an angled spacer plate being used to replace material that has been cut off at an angle on the intake side of the head. They will also be looking for the OEM angle between the intake side of the head and the block side of the head. That is what the +/- 2 degree allowance is about.

Any intake manifold,don't screw with the intake surface of the head is how I understand it. Years ago when John Gunn was torn down NHRA wanted to look at his manifold and he told them no I'm allowed any intake and locked it in the trunk. He said you're not going to look at it and tell all your friends,he got the record and never showed the inside of the manifold.

And, As I understand it, this is really just an attempt to stop creative port increases. If you don’t change the angle, then you would not be able cut as much off the head. to use a spacer as an extension of the intake port. Maybe they should allow the heads with angles more than 2 degrees, but add in the volume of the spacer and add that to the port volume? I am pretty sure anyone with heads that are modified that much know why they did it and what the rule means to them.

I'd like to see a Chevrolet intake on a 383 Mopar. Two very different platforms, and there are plenty of decent enough Big Mopar intakes to not warrant the need for that.
That being said...on the Cadillac topic...Cad500parts.com has the answers to all your Cadillac high-performance questions. |

The BBC has a pitch of 4.84 and the Mopar BB has 4.80. The port runner layout for both is: 00 00 How about fitting a 351-C intake on an FE engine? It can be done with the adapter shown below: ![]() Engine builders and racers can get creative in many ways. Nevertheless, what is the fuzz all about when they allow sheet metal intakes? As a matter of fact, Buicks are adapting Mopar intakes. Last edited by SSDiv6; 12-07-2019 at 07:44 PM. |
