1.6 Roller Rockers.... Installed!!

Hey folks....

I just got done installing a set of Comp Pro Magnum 1.6 Full Roller rockers.... and I must say that I am way more than impressed with the results...

My 350 was completely rebuilt about 10k miles ago.... the only thing that was original was the block... we did the following mods...

Bored .30 over = 355 c.i
Flat top pistons
Comp Cams .500/.510 lift camshaft
Springs/Lifters (For Higher lift cam)
Headers
Bumped up timing
Heads/Intake Manifold bored a little bit....
Custom burned chip based off the car's mods..
Complete MSD Ignition system (Box/Coil)
Removed Catalytic converter
Moved Air temp. sensor to air intake from TPI plenum
Homemade air intake with K&N Filter
New Injectors (21 lb)

Anyways... The difference between the stamped steel 1.51 (supposed) ratio rockers i had on there before today compared to the 1.6 Full roller rockers is incredible...

I apologize that I don't have any hard numbers to give (no dyno anywhere around here) But in this case I don't really need any to notice a difference.

My car has so much more low end power it's ridiculous.... My acceleration has jumped like crazy... I know I sound like i'm just babbling but holy crap.... Im getting put back into my seat even when I just ease into the pedal.. and when I floor it all I can do it smile

The one and only drawback to me doing this is that it really shows me how bad I need to upgrade my intake components to some higher flowing ones... I still have the stock TPI runners, stock throttle body, and the stock intake manifold, that "TPI Wall" really comes fast for me now.....

This is one modification that I "STRONGLY" recommend to anyone looking for easy power.... all it took was one afternoon's worth of time and I couldn't be happier...
