Re: Getting a TR224 Get the 918 springs, titanium retainers (optional), 7.4 chrome moly push rods, new timing chain set (depending on mileage), new GM crank bolt, new GM front cover and water pump gaskets, and new GM front seal.
We can install that for you also <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Getting a TR224 The stock ones shouldnt break.
Correct me if I'm wrong, but I thought the main reason for switching to titanium retainers was to lighten the drivetrain. But, the stock retainers are tiny (in comparison to older small blocks) so its not like you are doing the same thing as you would to a 69-79-89 small block.
Am I right in saying that the gain to be had from this switch on a 6600 or lower reving application is marginal if any? Dont get me wrong; this thought is limited to the 26918 spirings of course. If I was to upgrade to a bigger spring that necessitated the use of aftermarket retainers I would spend the little bit extra for the titanium. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Re: Getting a TR224 Retainer snaps, valve drops, gets chewed up, chain reaction which causes other valves to bend when they hit their piston - how is that NOT possible?
<---- Makes sense to me that if you drop a valve into a chamber at 4500 rpm that it will substantially **** a bunch of stuff up - please explain otherwise?

Re: Getting a TR224 Mike is correct in his explanation, it was more for the weight savings and making more HP at higher revs, same can be said for roller rocker's. The stock retainers should be fine with these springs for a 224 cam. There could be more involved with that broken retainer than anyone will ever know and is a very rare occurence IMHO...

Re: Getting a TR224 I agree Dan, personally I'd rather play Devil's advocate though when talking about the entire top half of this guys motor getting destroyed, it's only $160 (when put into perspective), which equals cheap insurance to me... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Getting a TR224 I'm surprised no one has mentioned a new oil pump. I would get the Katech blueprinted and ported oil pump...another piece of cheap insurance since the stock ones seem to fail every now and then.
Titanium retainers' sole purpose is to lighten the valvetrain...they are not stronger than the stock retainers. Simply put and conditions being the same, 1 lb of titanium is stronger than 1 lb of steel...two retainers of equal size (not weight)...the steel will be stronger.
I would also get a Cloyes timing chain...if I remember correctly, they are much better than the stock replacement.

Re: Getting a TR224 I definately agree that is cheap insurance and would do it myself for the piece of mind and only $160.

Re: Getting a TR224 I have looked into the oil pump thing. It turns out the aftermarket oil pumps are just cleaned up and deburred factory pieces. You can even do that yourself in your garage with the right hand tools. A factory pump cost me $80, while the Katech and other aftermarkets are only slightly more. Even with the stock GM pump, I run 60 pounds of pressure at less than 2500 RPM. I do recommend changing the chain if the engine has a lot of miles, or if you think you'll be leaning on the engine quite a bit.
I agree with you 100 percent on the retainer info. But, as I'm sure you can understand, I can recommend parts to my customers until I am blue in the face... If they don't want to buy them, all I can do is say "Okay!" and install what they want to buy. Many times it's not that they don't want to, it's that they just can't afford to spend the money. It's not hard to get $1500 into a good quality valvetrain. Truth is, most street cars aren't driven hard enough to justify some of the more sever duty parts. That's just my opinion.... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
