So I've been doing some research on which springs and retainers I should buy with the Kelford 272 cams. I've been reading alot of awesome things about GSC springs, but my problem is that I cant really find any info about which retainers are best paired with these springs.

 

you could try the ones that are sold with them as a package...

 

I heard the stock retainers are pretty good.

 

My reading = Fail

For some reason I totally didnt see the retainer and spring pack they sell right above it... Sorry guys.

Stock retainers won't work with a beehive spring.

 

From MAP website:The GSC Beehive spring is a factory replacement and will use your stock OEM retainer and Valve Seat to ensure an easy install.

*Max lift on stock Retainer is 11.4mm at the valve or .259" cam lobe lift.*

 

Umm yes you can?

 

From what I've and based on the note on MAP website, you "can" run them with stock retainers, but its not recommended if your running 272 cams.

 

I have hks 272 with GSC beehive springs, no problem at all
From what I know, the stock retainers are lighter then most aftermarket retainers.
.

 

Interesting... Is that what's important when it comes to retainers, weight?

On a side note, I heard some people talking how the Kelford 272 cams are a bit more intense on the valvetrain then most 272 cams, and that's why they require spring upgrade, where as some 272 cams dont. I have no knowledge of the HKS cams some i'm sure how the compare as far as spring upgrade requirements.

 

Stock retainers. That's what I run on the Kelford 272. If you are not reving past 9200 rpms stock are good.

 

My mistake, I was thinking of something else.

There was a thread a while back where a guy used a stock retainer with Cosworth springs and it damaged the retainer.

 

Actually you must run beehives on the stock retainers. FYI stock springs are a beehive design. They are NOT straight springs.

 

Well the GSC springs are designed for the stock retainers, so I'm hoping they wouldn't damage the stock retainers.

 

I have the GSC's with the GSC titanium retainers.
