Roller Cam and Roller Rockers

[Blwn87]

I have been eyeing the complete roller kit in the Poston catalog for a long time and am ready to get the $ and am wondering if its the right move to do. I have heard that in the true muscle car days to get big HP gains you would install a hydralic roller cam and roller rockers. Is anyone running the combo and what kinda HP,1/4, or seat of ur pants difference did u recieve and is it a good idea to run on the street?

I ordered the 206/206 roller kit from weber, but I have not installed it yet. From what I hear from numerous mechanics, is that you'll see at least .2 tenths and between 25 - 30 hp if you go from a flat tappet 206. I shall see though when I'm done. I have a 206 flat tappet in the car now.

I have ATR's roller kit. I don't know what gains I got just from the cam since I did a complete rebuild at the time. But it is EXTREMELY easy to install as compared to some of the rollers I hear about out there with thrust plates and stuff. Their cam installs very similar to a stock cam. The car idles great and pulls VERY hard.

Somewhere or another I have records from when I degreed in both a 208/208 hydraulic cam and the PT&E 210/210 econo roller. While the duration at 0.050" was (obviously) very close, the roller got to 0.25" lift 20 deg quicker than the hydraulic did. In other words, the roller had 40 deg more duration @ 0.25" lift than the hydraulic. That's gotta be worth some powah! Wish I didn't have to yank it out...

Just to clarify, the hydraulic had 54 deg duration @ 0.25", the roller had 96 deg. Get a lot more airflow with the valve held open that extra amount I suspect.

Last year, when all the roller cam fiasco was going on, I saw someone mention that Comp was going to look into making a good quality cast roller cam, comparable to such offerings for SBCs and such. Anyone heard of any progress on that front? Wonder if it'll ever happen. I'm not going to drop the $$$ for a billet roller kit (I just cut my losses and went back to a hydraulic), but if I could use my old parts with a new cast roller that wasn't going to crap out after a few miles, I could be swayed to try it again.
