Guest Mike Posted October 15, 2006 Share Posted October 15, 2006 Yes... I searched:confused2 I'm just looking to improve the performance/reliability of my stock rockers on my 350 Gen1 SBC. I'm having a 406 built soon so I don't want to waste my cash. Are these okay for cheapies? I'm considering the 1.6 ratio with a mild/mid street cam. http://cgi.ebay.com/ebaymotors/PROCOMP-SHAFT-MOUNT-ROLLER-ROCKERS-CHEVY_W0QQitemZ180038120145QQihZ008QQcategoryZ107063QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Quote Link to comment Share on other sites More sharing options...
getZ Posted October 15, 2006 Share Posted October 15, 2006 Those are some pretty cheap shaft mounted rockers. As far as quality I wouldn't know. I have some stuff from procomp and it's been okay quality. If you are only running a moderate cam at best, shaft mounted systems are an unecessary expense. They are for high rpm rocker stability when you start reving up above 7000 with a big lift cam. If it was me I would go with somebody elses roller rockers and save a few bucks, but that's just my opinion. I really like my steel comp cams roller rockers, but those cost more than those procomp shaft rockers Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 15, 2006 Share Posted October 15, 2006 Thanks getZ. One of my reasons for going with shaft mount rollers is to get rid of the guide plates. I just hate adjusting them. For this motor, I think the cheapy Procomp brand are probably okay. However, I'm still open to suggestions and am listening to caveats.

tfreer85 Posted October 15, 2006 Share Posted October 15, 2006 Just be careful Mike. I had bought a shaft mounted roller setup for my 1st Gen SBC (stock heads) and they had clearance issues at the rocker base. I know they're cheap but like getZ said unless your revving fairly high or making some really serious HP its not going to be worth the money or the machine cost (at least for me) to get the proper clearances, when you can do something better. I went with a roller tip rocker arm instead and am happy with it, its just a nice little cruiser type motor. Tyson Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 15, 2006 Share Posted October 15, 2006 Thanks tfreer85. I know you're both right... you get what you pay for. However, this is a temporary upgrade and I'm having a 406 or 434 SBC built soon. For that engine, I'll opt for an $800+ name brand setup. Hopefully, prices will drop a bit by then. Sheesh... the Ford and Mopar varieties cost less than half as much for basically the same thing. I'll ask the seller whether these will require any machine work for a Gen1 SBC.

280zwitha383 Posted October 16, 2006 Share Posted October 16, 2006 Are you talking $800 for rockers? Why? Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 16, 2006 Share Posted October 16, 2006 280xwitha283... Because shaft-mount rockers cost that much and they are the most reliable design. However, by the time I get around to having the new motor built I may chicken out and buy some less pricey. Quote Link to comment Share on other sites More sharing options...
280zwitha383 Posted October 16, 2006 Share Posted October 16, 2006 How many rpms are you trying to get and how much lift? Quote Link to comment Share on other sites More sharing options...

For this motor, I think the cheapy Procomp brand are probably okay. However, I'm still open to suggestions and am listening to caveats. Mike, Adjusting guideplates is a simple procedure and a pretty basic part of engine assembly. Considering shaft rockers (which are unnecessary in a street and even many racing applications) just to eliminate a normal engine assembly procedure is very backwards thinking. If you feel that the guideplates are too much trouble, have a machine shop assemble the engine. You have probably spent more time researching the shaft mounted rockers than what adjusting the guideplates would have taken. The KISS method usually works best, especially on a street engine.

Guest Mike Posted October 16, 2006 Share Posted October 16, 2006 RPM's and LIFT... just 6.5K and mild/moderate lift. I know what you're getting at but for a couple hundred bucks the shaft roller rockers are very tempting, don't you think? Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 16, 2006 Share Posted October 16, 2006 jakeshoe... It's my excuse for buying them and I'm sticking to it:confused2 I just want some cool rockers for my current engine:mrgreen: A couple hundred bucks isn't so bad for that. Now... for the next engine (probably a 406) I'll shoot for 7K RPM redline. I'm not implying that I want only the best for the next motor, just as near as I can get without taking a second mortgage on my home:cool: Quote Link to comment Share on other sites More sharing options...
