The Crane 227 is a great cam.. just a little on the small side for what he's looking for.

Ummm yeah...not worth the swap in my opinion.. very little gains. You be better off with Lloyds Hot Cam grind. That's even a mild cam as well.

I went 115 mph with the 227 cam with a set of very mildly ported heads. Thats faster than a lot of bigger h/c cars sadly. Shift points were around 6k for me with that cam.

It's a low end cam (227)...if you want something that will give you more mid and top range power look elsewhere. Our cars already have good low end as it is that's why I suggest looking into something else...Lloyd will tell you the same.

If you want a low end torque monster then the 227 or the LE version would be a good choice.

hmm i just did all the searching my brain can handle. the 227 is more stock then anything but makes good torque (which is nice in a DD) as you said elliot. and the 503 is a hard revving hp freak. now i have to figure out which i want.

If he wants a cam that is friendly on the stock bottom end then he is going to want one that works within the stock rpm range of the motor. And the 227 cam gives impressive gains across the board, not just low end. I don't think 115mph with a mail order tune out of heads that flowed 230cfm is exactly a slouch.

Don't rule out the LE version of the Hot Cam if you want something in between. Really depends on how you want the car to drive and what you are comfortable shifting at..

I think there is a misconception sometimes about big cams and stock bottom ends. It seems like some people have come to the false conclusion that a cam will hurt the motor. The only thing that hurts the motor is your right foot. So the point im trying to make is you can have as big a cam as you want so long as the rest of the valvetrain can handle it, BUT you may not be able to get the full potential out of a big cam with out being able to rev the engine higher.

just trying to clairify in case some newbs came under the wrong impression of big cams.

Keep in mind he's doing a cam only and not heads so your experience with this cam will be different then what he will.. I've driven in a bolt on LTx w/ the 227 and it dies out pretty fast in the mid/top end..I've seen numerous guys run that cam and end up changing it out because of the lack of power. Just trying to stear him in a direction to where he won't regret and wish he had gone a little bigger. And I'm well aware bigger doesn't mean better in all cases.

^ ^ i agree with all of that. theres no point in me having to high of a revving cam if im never going to get it to that point and get the full capabilities of the cam. ive revved the stock cam to ~6k no problems. after the engines warmed up of course tho. idk how comfortable id be with the 503 then if that cams powerband is well into the 6300 range. the 227 then sounds like a good choice. but does anyone have any experience with LE's 224/230 .560/.565 112 LSA cam ? that sounds pretty good for a puller cam that wont push the RPM's much farther past stock

The 224/230 .560/.565 112 LSA cam that's the cam I've been trying to direct you towards..not so much the 503..that was more of something I threw out there because you said you wanted something that's not gonna beat the crap out of your bottom end. That cam up top is his version of the H/C..I personally think you would be happier with that over the 227. If you do go 227 then go with Lloyds version of it...you will get a tad better performance

that and its an LE cam and its gonna be good reading about it does seem pretty spot on for what i want. thanks for all the help elliot and everyone else. i have some time before i do that swap but im a person that likes knowing Exactly what i need plenty of time before i tear into it. thats what i have to do because i dont have a garage of my own where i can lay the car up for weeks at a time one day

Yeah take your time w/ making a decision..call up Lloyd and talk w/ him if you have any concerns..he will tell you himself that the 224/230 .560/.565 112 LSA cam would be a wiser choice to go with rather then the 218/224 .544/.544 111 (which is his Crane version)
