I have this motor in my 70 C20. Runs very strong, but if you are looking for a silky idle, this is not the engine for you. If I was to by the same motor again, I would not go with the deluxe. finally had to toss the Holley carb, ran horrible, and yes I even had it chassis dyno tuned. I thought the carb would be calibrated for the engine, nope. Just off the shelf carb, same with the HEI. Swapped it out also so I could get more initial timing without going over advanced at higher RPM.

The cam has a 108 LSA which gives it great low end with out sacrificing upper HP.
As long as you don't mind bumpy idle your golden. I do agree, go with a roller cam for reliability
