350 chevy roller rocker conversion to buick 350

Can anyone tell me what chevy shaft roller rocker arm can be used for buick 350 and if any machining or modifications need to be made. There was a post a long time ago about this, but it is no longer available. If anyone has information where I can find 1.6 or 1.65 for my buick motor I would greatly appreciate it.
I refuse to pay thousands of dollars to ta just for some rocker arms

 

Mark Burton used to make a kit to convert the iron heads to sbc rollers. Unless you find an old un-used kit that’s not an option anymore. I recently send mark his original heads he’d used to create the kit. Finishline also has a set of Burton’s conversion. It basically milled off the pedestals and used a plate to mount studs for SBC rollers.

 

those rollers do work good I have had mine on there for over 25 years. you could always use the hardened shafts for the rockers. With the rollers you will have 1.6 ratio as the sock ones are 1.55.

Those rollers are a lot of money they should not be that much.
seems to me the 350 has taken a crap here not many posts anymore.
but then who has money?

 

Yep, I noticed that also, pretty quiet in here, im sure money has EVERYTHING to do with it

 

I think I have a spare set of poston roller rockers I could sell. Send me a message and I will dig them up.

 

Correct me if I'm wrong but Buick 350 and 455 used the same stamped steel rocker arms. The difference was the length of the shaft/valve spacing they were mounted on. You should be able to take a set of 455 roller rockers and mount them on appropriately sized shafts for a 350.

My other thought is to find a suitably similar roller rocker arm and mount it on a Buick shaft.

Does anyone know of a comparable rocker shaft that could be cheaply sourced.

 

Kevin, (Storm1) runs these rollers. Angelucci Performance built them or sourced them for his build. They look very nice and close to TA's or T&D's...I believe they are 1.6 ratio.

Maybe something to check out as far as price & availability.

big dave,
fwiw, nascar spends millions on engine developement which includes valve train. they have running roller shaft rockers for quite a few years.
stud mounted roller rockers are old and nascar doesnt use them anymore and neither do we.
if you go stud, once you cut the head AND screw up, you have created a very nice door stop.
just my -.02$

 

X2, I always wondered why people want to use (convert) to an inferior rocker set up, either keep the factory shafts or upgrade to shaft mounted rollers. It’s almost like an oxymoron, your PAYING to go BACKWARDS

 

There is an LS setup that has the roller rockers in pairs on a short shaft, four of those per side which are mounted to a one piece aluminum mounting block which is in turn bolted to the head. Those rocker pairs can be used if you make your own mounting block. Not particularly expensive, I bought that setup but as I've been busy with the bus conversion and the mill is down I've not made up the blocks yet. However, I'm getting a digital readout for my birthday so I'll be back on that in another month or so and making the two blocks should be fairly easy. They are adjustable of course. Seems like the price might have been under $200.

Jim B's setup looks similar to these but the pushrod offset is closer together like in the Buick. You would still have to mill the pedestals down on the stock heads.

 

Was originally going to use Chevy rockers on my aluminum heads but my machinist refused to because he didn’t like the geometry. Too much of a side load on the guide plates for one.

 

These are the one's Jim B has. Not LS but you can see the closer pushrod offset. Price is a lot higher now.

I messaged this guy to see if he had 350 roller rockers, he said, "unfortunately no".

Mart, If you change the spacing for the hold down bolts the 455 ones may work?

 

Yep, if you bought new shafts, might be a price wise wash.
Redrilling may weaken shafts too much.

They seem to be same offset as 350's.

 

awhile i bought some ford stud rollers, 1.6 and 1.7 and i have t&d 1.65 and ken-bell ? rockers. i think i can make the ford's work on the v6 or v8. but its a next project

 

Can someone post up a picture of a stock SBB head to see?

If you have roller rockers from 1995 you should change the bearings in the roller rockers before they eat up the shafts. Mine finally ate into the shafts and have to get new ones and new bearings.
I noticed only the four center intake rollers dug into the shafts. This could be from more heat in that area since the exhaust is in the center but could not say for sure. I ran synthetic Mobile 1 the entire time.

The point of this is the new rollers for the rockers are a lot tighter between the rollers as compared to the old ones so if you have the old sets change the bearings now before those shafts get worn.

I will try to get pics together if I can get them in this computer as I am also changing the cam too and this is how I found the problem.

oh 1 more thing as Columbo would say these little batards cost 12.00$$ a piece and that is times 32 so you get the gist of this.
and those shafts are a buck and a quarter just for thits and giggles.

Almost what I paid for the whole set up in 1993
