Reply to "What is a must to do ?"

For me, even for a race car, it is too radical.

I like this one better and it is the one that I am using.

It is ok for the street the way I use the car, but is too much cam for a car that you would want to drive everyday and in traffic.


With the heads that I am useing, Ford A3, with the .605 lift, the heads flow 330cfm on the intake.

That is more than the engine is capable of using.

It is putting the power range in the 4,500 to 6,500 rpm range yet will rev way over 8,000 rpm but I don't need that level of rpm.

I have it idling at about 750 right now with the Webers.


The cam you are asking about is .640 lift. With a 5.7 L engine, there is absolutely no point in that with either the iron 4v heads, with my heads and probably any of the other high port heads UNLESS you plan on running the engine to 8,000 to 8,200 rpm REGULARLY.

Even if you do, be prepared to rebuild the engine after every race or even an extended high rpm jaunt.

With a Cleveland UNLESS you are seriously drag racing the car, you don't need to go more than around 6,700rpm on a road track.

At that rpm in 5th gear you are going to need to be a very skilled driver to not crash it.

It is likely to be as fast or faster than almost anything of it's era that you are running against.

It is powerful and agile. That is the highest level you can achieve with it.
