Put a TR230 cam in our 00 SS M6. Used the ti retainers and comp 918 springs to go with the new cam. Also replaced timing chain with LS1 factory replacement since we were already "there" anyway..
Problem we ran into was we forgot about the spring seat locators...YOU WILL NEED NEW ONES DONT FORGET...because the springs are a different size, so we ordered them from comp. and had to put off the finish a few days
Got everything back togather and took her to tune and dyno friday -
377.2 rwhp and 370 rwtq

We had already pretty much standard bolt on mods - slp long tubes and mas, 411 gear etc...

She is my daily driver and i think this was a good cam for that. The tune really smoothed out the start and idle and the new power feels good.
Guess the 12 bolt is next hopefully we get a few good runs before we break the 10 bolt!!

Would like to thank LS1 how to for the great write up for cam install!!!!! This is a wonderful write up to have when you swap cams.

Are you sure you didnt use 921's? 918's are direct drop in replacements when I did mine. Which tr230 did you use? The 230/236 or the 230/224? The 230/236 would have required 921's and the 230/224 918's

Aren't you suppose to be getting closer to 400 Hp... If not more with that cam. Thats the one I think I want to get.

Spring seat locators? My 918s dropped right in when I put my TR224 in.

the cam is the TR230 - 229.6 intake 224.6 exhaust with lsa 111
we put the 1.7 rockers back on valve lift .577 intake .568 exhaust

yes we used the 918 springs and the stock spring seats were about 40 to 60 thousands too loose and according to the tech at comp cams it would let the springs float a bit at the bottom at high rpms. They suggested we use different ones. When comparing the stock spring to the new 918 spring you can see the larger diameter at the bottom of the spring not to mention the 918 is a bit taller. Im sure you can use the stock seats but comp puts out the ones that are made for the 918s because they fit perfectly to keep the springs from walking from side to side at high rpms.

This cam is suppose to add i think 30 to 60 hp to what you start with (i think thats what i read anyway) but we have found that you need to lean to the lower end of these numbers on most parts.

Hubby wanted this cam because of the power band it produces mid to high end.

I have the same cam and no problem with the 918's.

370hp is very low, you must be missing some bolt-ons.

Those #"s are kind of low. Does your car have an LS6 intake? Pully?

LS6 on a modified engine should give you at least 15, if not more.

LS6 intake, ported TB and underdrive pulley should get you to 400 rwhp.

I used to run the TR230/224 in my car with ported stock heads, pulley, LS6 intake, LT's, etc... it went 11.58 @ 118 but only dyno'd 399/381... mainly due to me being on slicks on the dyno and having a 9". With a 10bolt and radials I bet I would've been putting down 435 or so. Either way, that cam pulled ******* hard and I loved it!
