Depends on the application. Longevity for a endurance application is different than for a drag race application. That is your point, right? It's not uncommon for a drag race engine to sacrifice longevity for power.

Yea pretty much. Imo unless u spend a trillion dollars, you have to sacrifice certain things. As u said, power for longevity. I called Brodix today as well and they said the bronze guides are what they use in all ls7 heads

I wouldn't worry much about 'durability' either. To a greater or lesser extent, most of the guys I know with dedicated racing applications tend to do a rebuild after every season or two.

Just the cost of doing business......

The build parts are quality from the oil pan to the intake. Whether they are stock rockers or bronze guides. It is what it is
That's fine - I don't build drag race engines, I build endurance engines that spin 4k-8k+ RPM for 40-80 hours non stop between refreshes. Abnormal or accelerated wear is unacceptable in those applications.

thanks man.... im pretty happy with this hydraulic roller.. im sure solid may net a few more hp but the price for the rockers and complete sr set up wouldnt justify it in my opinion...


i think i left a few horsepower on the table as well.... i dynoed the motor with 1 7/8 headers but i will have 2 inch headers on my car.. should net about another 20-30 im hoping

Yeah, that's the point - likely came across harsher than I intended. Again, great numbers, I just look at things from a longevity standpoint first.

I would think that cam spec'ing is more tied to compression ratio than to cubic inches.

Yes....there are other factors involved, but cubic inches is a lesser factor than most people think.....

when he said that he caught me off guard as i am no cam expert. i dont even know if he knows his face from his *** but i thought id ask on here... he was saying torque should be higher in regards to horsepower but from most race engines ive seen horsepower more often then not trumps torque by a lot.

I ordered a pair of RHS LS7 305cc FRH and for street application FRH suggested the LS7 lifters with trunion upgrade. For the exact same reason Strokedcamaroz28 said..... it's true some of the stock stuff now a days are just as good if not better than the aftermarket.
Another suggestion that kind shocked me were the HR.....johnsons ST; same one used in the stock COPO Camaros.
