You guys out there that have put them in after having a 3200 RPM spring. What are your thoughts? Is it worth it? How do you like it? Drivability? Towing, daily driving? Racing? Lets hear it.


Thanks

It's worth it
Only place I ca find that can get it is Schied's, so give them a call on Monday

Any bosch certified shop can order that spring....it doesnt have to be schieds. I ordered mine from a little injection shop in central Texas three years back and I've been running it with no complaints. Its doubtful you'll see the full benefit of the 4200 spring unless you have 60lb valve springs as you would float the valves before you saw that kind of RPM's.

Thanks guys, I already have the 60LB vs's I am planning on installing them @ the same time.

Thanks

Also you'll want the heavier high rpm application plunger return springs in your VE. Get ahold of KTA for part numbers.

thanks for the tip Bill. I have heard about that. I don't really plan on running that high very often. I don't know much about the inner workings of the VE so that maybe a job to let some one else do.

Thanks
