I pulled my old 228/232 cam in favor of a smaller cam. Its been in for about a month and has been great. Nice smooth idle and cruising, almost stock like. Which is what I wanted because my wife is driving it more than me and she hated the old cam. I had it tuned pretty well but she still didn't like the cold, low speed characteristics of that cam.

So got a cam from EdC at FTI, a nice baby cam. 220/224. Finally hit the dyno and it did amazingly well compared to the old cam. Actually made more power up to 5400 than the old one. Then that one started coming on but the stock clutch slipped on the dyno, so I don't know how much that cam would have made. It did make 427/388 on a dynojet before the Yella Terra rockers though.

Anyway, here's the graph of the two cams. Made 405/385.

A friend installed that cam on a 112, made a shade under 400 hp with stock heads.

Mine is also on a 112. I would be curious to see what it makes on a Dynojet. I know from when I did it last year, the curves were a good 10 less. And that was with the rockers added which I'm sure only make 1 or 2 hp if any.

It was nice to see it making more power with the heavier LS7 clutch and stock catback vs the stock LS6 clutch and Corsa Touring catback.

What other mods are on the car? Those are some strong numbers for such a small cam. Very nice.

Ahh, the heads would explain it. But that's still some great power for stock-like street manners on a daily driven car. Congrats.

Then ed Curtis designed for you a smaller cam than your previous and you made more power with only cam change!!!

Those lobes he used for your stick must be magic...

Read his post again.

Yes, smaller cam...more power. At least more useable power. The other cam did come on pretty good up top though. But the car is really too heavy for that kind of cam.

So more power with a cam change and loosing the catback. Nothing wrong with that

NicD,
I was looking at your old graphs and mine look pretty similar to yours. At least before you put the FAST on. I'm really digging this cam!

Thanks for the help before I put it in.

The best of the both worlds...more usable power and a grocery getter to please your wife!!!

With only going for smaller camshaft numbers at 0.050.

Looks strong! I cam cam shopping still and dont want to do the job more than once at least for a year or so, so I am still researching but am getting tired very quickly now and I am just about to buy anything close to a 228 cam and call it a day.

would you suggest the 228/232 cam for an 01 6 speed fbody with stock heads and full exhaust?

I am looking for a flat tq curve for the most part, and about 400hp under 6k rpm, not wanting to rev past 6k to make peak.

I was looking at a comp cam on xer lobes 228/232 .588/.595 111+2 lsa?

Rob

iTrader: (6)

That is the cam I just took out except mine was on a 110+2. My torque curve wasn't flat as evident from the graph in my first post.

It would definitely work better in an F-Body than a GTO but it did make power. I would talk to the sponsors of this board about what your goals are. Or go to who I went with. Either way, you'll get a better cam suited for what you are after.

Found the old dyno from that cam. This was from a GT2-3 to the 228/232 cam

thanks for your response.

well I need to stop using flat in my terms, more or less I like how the 3-6k range on urs looked. starts high down low, goes up alittle bit and peaks, then goes down slowly but stays about where it started.

either way nice gto!

Sounds like the same cam I have. I bought is used from Ed Curtis. It was apparently a blower cam used for dyno testing a GTO. Mine is on a 114 lsa. Gotta love these small cams. Nice results!

Thanks. I guess "flat" is relative. I was going to advance it to see how big of a increase in the low end would have been, but just decided to change it to make it a nice easy driver.

Rob

iTrader: (6)

Thanks. I don't know if mine started out as a blower grind but it does the job. I know this cam has been around in one form or another for a few years. My buddy had a 220 cam from Ed in his goat and it made 435/405. The specs are different between mine and his.

I was thinking of running one of eds cams in my new motor. Nice looking power and curves. I was looking into running his StreetSweeper cam in the new motor.

Why in the world are you thinking so hard about it! whatever you do you probablycant tell difference in seat of your pants Just try something other then XER lobes.

What do you want to shift it at stock rpm for? Cant understand people saying that. Make use of a perfectly good cyl head/valvetrain/bottom end. That cam will want to be shifted at 6700. Hell 224 cams want near that much depending. Look at his graph peak at 6400 shift at 6800 or so. 211 dur cam peaked at 6000 rpm. Youd have to do something a little different to do what your talking about

Haha, no prob. I really do like the cam a lot for a daily driver. Awesome manners to the point of almost forgetting you have a cam and gobs of power and torque to go with it.
