Do your TSP headers and Y-pipe tuck up nice, any fitment issues ?

WOW thats a huge cam for a 98 the motor will probally blow with you spinning it to those RPM's recommend I would choose something that isn't as big. Get a custom cam from PatG and be done with it. Good luck with what ever you do though.

Really? I'm not gonna be spinning it past 6 unless I'm at the strip, even there it will probably be only 6200 max.

I think that is a huge cam for a stock bottom end LS1 especially the 98 with the weaker rod bolts. If you arn't going to run the cam to its full potential at 7200 RPMs then it would be pointless to get a cam that is that big. I think that there is better cams that would meet your needs better. I would highly consider specing a custom cam with PatG for your RPM range or getting a smaller off the shelf cam that would peek in those RPM ranges.

I agree, this cam does not make much sense in the context of 6200RPM shift points and stock displacement.

The EPS 222/226 .597/.598 113LSA would be better, or maybe even the 218/226 .595/.598 113...

Interestingly enough, if you go by the rev range that EPS labels the cams the closest would be the 214/220 .600/.564 115 which is listed as 1500 to 6500 RPM Operating Range. It has a smooth idle though, and I think if you wanted something even more ideal power wise, but giving up a little idle quality you would want it on a tighter LSA... I don't have the information for the duration at .006 or .200 so it is hard to say exactly but I am sure that Geoff at EPS or PatG could help you with that. Granted if you are going custom then a 222 on a 110 or 111 might end up making more sense, I just don't have all the numbers for that lobe to speculate too much.

Honestly people have gotten way too hung up on duration at .050 as some sort of measurement of manliness. You want to match the cam to the rev range, not put in something with more duration than is needed for your RPM... all you will be doing is giving up power in the operating range for some peak way off at 7000RPM that you will never see.

you can get some used 243s for $400.you can get a used ls6 intake for $300.get good valve springs,harden push rods ,and comp trunnion bearings for the stock rockers.keep the stock parts for restoring the car to stock for testing.

I agree 100% with Haz-Matt.

I've seen way to many cars out there with way too much cam for the combination. I like the 222/226 on 113 for what you've got.

Alright, guess I'm gonna have to rethink the EPS cam then. Thanks for the advice guys. Well I'm set at a 6200 limit right now, once I do the cam and get the engine to handle it, I'll probably put it at like 6800 or maybe 7000. How much weaker were the 98 rod bolts though? I want somethin with a really nice lope that will push me atleast to 400rwhp. I'll start up a new thread with what I'm lookin for and let me know of your reccomendations there. Thanks guys!
