You might be able to alleviate some of the poor performance, but you can not eliminate the damage a badly designed intake path does to the power output of a cylinder — w/o redesign.

Absolutely, completely agree!

- Get a different race car.
If you are not racing the car competitively either;
- Enjoy it as is,
- Build your own intake,
- Get a different car.

Not racing the car competitively. I'm more of a drag racer, but I have other weapons for that in the shop. I bought/ inherited this car from my dad because he was no longer able to drive it and I have many fond memories in this car with him. This winter it is getting the 418 stroker I have been working on. I just need to contact Blykins for a cam and some other small parts.

Good driving skills vs poor or mediocre driving skills will make a much bigger difference.
If you have excess energy that needs dissipation, buy a set of worry beads and rub them regularly. It is less expensive and equally as effective.

Not fretting at all. The motor that is going in should be over 500 hp (more than enough for the car). I was just asking if anyone had knowledge on the 4 pattern cams as it is not something I have dealt much with first hand over the last 20+ years. I am sorry if I have rubbed you the wrong way but I thought this may be a good place to ask as I have read numerous posts with good information. Even though I have been racing, fabricating, and building engines for quite some time, no one knows everything.
