107... Big IF
Do a search , the Thumper cams don't get a good review because they mostly make your engine " sound " lumpy because of the big overlap
There are better cam choices for a 383 out there .Look at the many online 383 builds and see what cam they used.
Why try to reinvent the wheel?

Re: zz4 or comp cam thumper
with the thumper cam your going to get more power and sound obviously but your going to have a lot of "fun" tuning for that...
the zz4 cam you wont have hardly any trouble tuning for and will still net you a good amount of extra power.. Personaly, I would go with the zz4
