Very nice. As to horsepower I will guess maybe 300rwhp. I am assuming the parts were just bolted together with no porting.

Re: Anyone using this combo, what kind of #'s

maybe 300 hp..id look into doing more with tpi intake for easier hp gains, not sure about the specs of a lt4 cam but if your looking for quarter mile times you might see mid to low 13's judging on the shifting

whats compression ratio?

my set up is
-355 brodix 180 cc aluminum heads w/ comp cam extreme energy 280 .520 lift, hooker shorty long tubes, 3500 stall stock bottom end 10.5 compression, 750 double pump rpm air gap. estimated 390-400 rwhp and im about 12.50s. good luck

Re: Anyone using this combo, what kind of #'s

I also could go with a Holley Stealth Ram with 30# injectors and a 58mm TB and ZZ4 113 Alum Heads. Undecided right now. Is there going to be an issue w/ hood clearance. What kind of numbers do you think this will give me with all the other things listed above?
Thanks
