Industrial Hemi for Street Use

[JJ]

I have (2) 331 Hemi engines IND 56. I plan to put one in a '35 Ford Pickup. While looking for engine parts I came across a statment that Industrial engines are not recommended for street use, http://www.earlyhemiengineparts.com/indexframeset.html
Can anyone tell me why?

The cam is set up to run at one set RPM. It'll have to be replaced/reground. many have extra water holes in front, so you would have to use the bulky front cover that came on it. Check & make shure the heads have the oval exhaust ports,instead of the small round ones

Thanks, I was planning on replacing the cam anyway during the rebuild.
