I'm getting some 272/272 Cams and am looking for the following
Manley Performance 4G63 Spring & Retainer Kit

Can any of you guys recommend a good place to get the above kit?

Cheers
Matt

 

slowboy racing should sell them. They may not be listed on his site...but I know Mark can get them.

 

yep just contacted Mark, just hope i dont get stung on shipping/taxes as i'm based in the United Kingdom.

 

I dont know about Manley, maybe mine was just unfortunate.. but when I used them on my turbo honda I dropped a valve because 1 retainer cracked and what do you know entire motor was destroyed. Since then I have only ever used Ferrea or Supertech.

 

where can i get ferrerea or supertech springs/retainers then?

 

same place or AMS sells them. Loads of vendors on here actually. Z1....contact adam.

 

what do you guys think of these?
SI Dual Springs w/ Manley Titanium Retainers:

Me personally I am going with supertech because that is what I trust. I reved my old honda to 10k and had Manley on my head for 4000 miles and the manley retainer cracked, Replaced with supertech on my new head reved to 10k for 2yrs straight while turboed, Just my personal experience maybe it was a flaw in the retainer and I was unlucky.. And believe me the worst thing you can do is drop a valve Entire motor probably is trash.

 

did you properly chamfer the springs before you installed the top end?
did you also check seat height?
was it a stock valve?
I have never had a failure with any Manley parts for any car
usually its installation or tuning error
i had the same motor running 4 straight years with many track events
with only a refresh build every season to check tolerance and re ringing

 

Yea I knew that was coming, I been using same machine shop for 5yrs, Houston Engine Balancing, The guys name is Tommy Costales, use to be a pro racer so I am sure he knows what he is doing. Here is website http://www.houstonengine.com/

Why dont you go with the Piper Race Cam kit. They are 272 but if you look at the hard numbers they are more agressive then most on the market. The kit comes with springs and retainers.

I have got the BP300 cam kit in my car which are thye 265s and they are a treat and rev out nicely.

already bought the cams mate.
think i'm going to go with ferrea dual springs and ferrea titanium retainers.
