here's the deal, i've bought something else to drive, and the camaro is now going to be strictly strip with some street time. i want opinions on the benifit of going with a solid roller setup to accompany my AFR 210's.
if solid doesn't yeild a significant amount above hydraulic i don't see much point in fooling with adjusting valves every so often.

*streetability is not an issue...it's a th350 and will be stalled accordingly.
*the motor is a forged 355 with ~15k on it, staying fuel injected.


thanks for the opinions

You have to replace the whole valve train I believe, except for the valves. I've heard it does net quite a bit more horse power though. And you just adjust the valves every 3000 miles or so, which will take you a while to accumulate.

 

i understand the valve train issues....i'm fully aware of EVERYTHING needed to make it happen, i'm simply asking about perspective differences in power

 

Here you go man. Alot of info regarding this subject.

I just read a 25 hp gain over a similar hr cam.

 

Solid gives you the ability to go alot bigger and alot more aggressive on the cam lobes, its all in the cam you choose. With hydrolic, you are limited to how much the lifters can handle...

 

You might need to change everything. I'm working on a SR setup (taking a break from it right now to write this) and this set of heads needed new valves (longer), springs, retainers, locks, seats.... The rockers are upgraded to 7/16 stud units, 7/16 ARP Pro Series Studs, Stud Gridle and Valve covers to clear everything. Add on to that new lifters, new cam and new pushrods.

On a 355, you aren't going to see as much gain since the setup is not as limited by the valve lift as a stroker would be. All depends on the RPM you want to run. If you want the motor to peak HP around 7000rpm and spin it higher than that, then yeah a Solid Roller would work for you. That also needs a better ECU as well.

When you look at cams for something of this sort a solid cam needs to be about 10° larger @ .050" to be comparable to a hyd cam.

as stated earlier, i am aware of the valve train components that are in need of being replaced....the AFR heads already have 7/16 studs, but are assembled with springs for a hydraulic roller, which they are only good to 550 lift, so they will have to be replaced either way i go.

i think i'm beginning to lean back toward hydraulic on the account that i do not plan to rev the motor past 6500-6600 rpms. i think a good custom ground hydraulic roller should serve my just as well as a HUGE solid roller would.

 

Yeah and you will probably have to change out those AFR springs, they are pretty tame for a good Hyd Roller setup and don't have enough pressure to do the job.

i think i'm pretty well set, and that being said....
bret, i think you're the guy i need to be talking to about a custom grind....shoot me a pm when you get a chance and we can talk.
