Doug,
thanks for the advice (to George too !)
That's a good american engine sound !
here's what I have right now (new in box).

I was told something like 400HP with a good carburator and exhaust ...
what do you think ?
It will not be a street car, I need power from 3000 to 6500.
kind regards
Philippe
That's just about what you will get with that cam. Maybe 425hp with it going pretty flat at 6,500 but still will go to 7,000.
These engines are VERY capable of making 500 dependable hp AND safely run to about 7,400 to 7,500 rpm.
Frankly, with what you are telling me, what you were advised to pick is not enough cam for the track at all. It will have a lot of bottom end in first gear but will run out of rpm's too quickly and seem like it's short.
I would go with what I have (and I did). It is going to be just about right. It revs easily into the mid 7,000 with power.
I have mine idling at 650rpm. At that rpm it does sound like a speedboat burbling through the water exhaust.
I'm sorry. I tend to be a counter culture personality?Go figure?
Incidentally. With solid lifters, you adjust the valve lash with the engine off and cold. If you don't know how to do that, PM me. I'll give you the how to instructions. It is not difficult to do and you can do it in about 4 hours if you are not a novice.
