Dumb question of the day...
Are LT1's RR's specific or should any RR's for a SBC fit?

 

i believe they are specific...

 

Most any SBC rocker arm will work with trimming of the valve cover supports. Narrow-bodied rockers are less fussy.

 

What brands would you guys suggest for the budget minded guys?

 

The ones that I am selling

 

Well the Lt1 rockers have a formed tip that helps them stay on the valve tip. Some of the old sbc rockers just use guideplates.

 

Incorrect

 

I would go with a set of comp cams pro magnum series. Either buy them new or look in the for sale section as they are pretty easy to come by.

 

an lt1 is a reverse-cooled small block chevy. that's it.

 

I just got the Comp Pro Ultra Mags..they were a little over 300 bucks but they are supposed to be one of the best!

 

I have comp pro mags, they dont make them anymore but i havent heard anything bad about the ultra-pro mags.

 

When you guys installed your rockers did you go all the way with new springs and all that good stuff or just the rockers?

 

You should always replace the valve springs with at least LT4s or better when you install 1.6 rockers. A few people run 1.6s on stock springs but it is overall not a good idea.

 

This is out of my 95 LT1 from a vette and my 94 had the same setup. My 72 C10 doesn't have these kind of tips.

 

You're referring to Non-Self Aligning Vs Self-Aligning rockers (SA rockers are the ones that have the little tabs). Engines with guide plates and rockers without the tabs are Non-Self Aligning and are the recommended way to go in performance applications (per CompCams.)

Even though many GM engines come from the factory with a SA valvetrain, including the LT1/LT4 engines, the LT1/4s have a whole host of differences from earlier and later small block Chevys. Many of these differences cause the parts to not be directly interchangeable with earlier and later engines. IIRC, 92 through 97 were the years the LT engines were made.

Starting with the block (which is unique to the LT1/4) then the Opti-Spark distributor, camshaft cores, cylinder heads, intake manifold, the LT4 has 'net build' roller rockers made by Crane, water pump, etc.
