So maybe alittle black magic involved.

Is that what he called it? "Sacrificing" a goat?

That allows modeling and simulation especially with the computing power now available. At the very least, I would be interested in seeing what the calcs say. Secondly, it would be of interest to compare the theoretical with the empirical.

Wouldn't you have to have someone who specializes in 4cam engines and one with the same valve angles, chamber size & configuration ? then throw in limited valve lift & rpm [weak chains]
If you know someone like this Please !!! get us the info
Thanks

This might be blasphemy, but shouldn't Ford mod motor guys have a good idea about cam size vs. flow data for 4-valve heads?

Good point. I'm also curious about what software tool Todd P. used (if at all) to develop the cam profile he recently posted on the thread about his 427 project.
Here's his latest:

What Todd is doing is very different from what's been attempted before. We certainly have much more data regarding either stock or ported heads on a stock short block. I'm just interested in using a similar process for the for the "run of the mill" LT-5 mod. If its been done before, I'd be interested in the results.

Sounds like the "while I'm there" bug has hit. Xfire just spent lots of $$ on ported heads and doesn't want to put stock cams back in! I'm in the same spot.

I am about to be in the same spot. How about a limited group order and a discount !!!??? I have a 350 cube motor and will have ported top end inc. TB. Just about out of money for cam grinding even though I have a core set of stock ones to hand over. Would love to pick up that extra 20-25 ponies at the wheel.

I have pointed this out in the past Sean Hyland builds 600hp Ford DOHC Cobra motors.....also has developed cams.

Lee,

Could you post the ISBN# for that S. Hyland book? (ISBN# usually on the back - often next to the a bar-code.)

It would make for an interesting read.

Here's my take.

I doubt it but, if Todd were to loose any low end power with his cam choice he will make up with C.I.'s.

Basicly if Todd makes for example 650RWHP @ 7k RPM i'm pretty sure he won't be making zero power at 2k or 3k RPM.
I can't wait to see how it turns out.

650RWHP @ 7k RPM I'd love to see that one.
