Did any 90 to 92 305 camaro's come with a roller setup from factory?
Besides the corvette. Thanks to ALL.

 

88 and up 305s and 350s are roller cam in F-bodies

 

Yes...I have one for sale here

 

So I have a 1992 RS 305, are you saying ALL 305 & 350 are Roller?
How can I tell if mine is a Roller motor?

 

idk i got a 350 and it was a flat tappet best way is to open it up and pull a lifter. thats what i did.

 

I also pulled a TPI off a 1990 TA I just bought, it has a flat tappet also.

 

From the factory, all U.S. passenger cars 305 & 350, '88-up, got roller lifters.

If you saw something that fits that description that had flat tappet, either the cam or engine has been replaced.

 

Well that could be the case, I dont know this car, bought for the TPI.
Then the motor could be a 350, how to tell this by lookN at it?

 

its should say 5.7L on the driver side of the block where the tranny connects by the back of the block

 

I once heard that you could tell by the Harmonic balancer, is this true?

 

i have 2 305 ho rollers one needs to be rebuilt and one is rebuilt..one has e-tech heads and the other has v-tech heads both have 5.0 ho stamped on back of block

 

yes it is 350 have a thinner one and a 305 has a wide one like 2 inch maybe and the 350s is like an 1inch

 

Thank You Vary Much

 

np did you find out what it is?

 

Not yet

 

ITs going to have whatever balancer is on it, they are interchangeable. The only way to know what size engine it has is to get the casting number off the block. Same year, same car is probably going to have the same balancer installed.

 

if its a stock balancer and its skinny its a 350 if its wider its a 305 but im not gonna argue over this... who would change a balancer and put a 305 one on a 350 or vise versus thats would not make sense but w/e

 

OK, the 1990 Friebird T/A has the narrower balancer, 5.0 on back of block.
My 1992 Camaro RS has the wide balancer 5.0, why to different balancers?
I guess the difference in the years maybe! It really dont make any since.

 

wierd my 91 T/A has a wide balancer also and its a 305...

 

Depending on the year and the specific engine, they are not different at all, they will have the exact same part number. I'm glad you wont argue, because you are not right. Why would it not make sense? The balancers are not CI dependant, they are dependant upon the diameter and how it works with the rotating assembly and timing tab.

 

balancer may change between stick/auto

 

FWIW, the 5.0L in my '87 IROC has a factory roller cam.

What's also strange is that it has center bolt valve covers, but it doesn't have self-aligning rocker arms. It also has the lo-po rotators on top of the exhaust springs.

 

another tough guy

 

I'm not a tough guy at all. You are handing out bad advice, you were wrong. That doesnt make me a tough guy at all.

 

oh alright sure but w/e some motors you can tell like!!!! that can you not?

 

Well all I can say is that the balancer is diff. from 1990 Firebird to a 1992 camaro.
Both are 305 CID both are a AUTO. and they are both center bolt valve covers.
So you STILL have not said why the bal. is DIFF. Thanks.

 

No, you cant. The press fit size of the balancer is the same between the 305and 350. They will in fact use the exact same crankshaft casting, just a different balance. The balancer can differ depending on pulley/belt configuration, timing cover/tab configuration (Actually the tab changes per the balancer, but its all the same), and possibly the trans combo (although I havent seen proof of this being a deciding point). The only real engine you can tell the difference on is a 400. 305/350 is the same.

 

not mine i have a 305 and a 350 and they are different so your wrong...

 

Im sorry, I thought i was dealing with a grown up person here with common sense, my mistake. I can post part numbers if you would like, but what good would that do. Sometimes I wonder where kids learn it all at such an early age nowadays. Take the one off the 305 and put it on the 350, did he 350 just lose 45CI?

I went ahead and got the part numbers. Here is a lookup on a 1988 camaro:

305:

27-305-F 12551537 $157.22

350

27-Vibration Damper 12551537 $157.22

The first part is GM part description in alldatapro catalog. Then part number and price.

 

You have NO clue what you are talking about. I have seen 350s and 305s BOTH running either 6 3/4" or 8" diameter balancers out of the factory. Just depends on the year and application. Most of the performance cars ran 6 3/4" balancers and trucks typically have the 8" balancer. As long as you have the timing cover to match it is 100% interchangeable between engines as even the FACTORY did it!

 

man STFU i was told i was wrong cant you read above so uhhh yeah so keep on talking that im done at this post...
