I was thinking about getting these, and was wondering what type of experiences people have had with them. Thanks for any input.

 

They are having the manley springs over .500 put in along with arp screw in studs and guide plates. And porting the intake only. But im not sure if i will port the intake b/c the vortec's flow pretty good already. But That base they need to drop the price sum. I am thinking of selling the set up once they are done and probably not use them as Im going to try and work with some Afr tricked out 195's and the Super Ram base thats ported along with the rest of my set up. This set up on the charts was around 410hp. but that's also with a 236/242 @112 lobe/ this cam is supose to be real nice. I await end of year to instal.
