Default Steeda #18 Cam: Has anyone gone fast with this cam?

We are working on a 85GT project and we have already done all of the bolt-ons like a better intake, 650 D-pumper carb, underdrives, shorties, exhaust, T-5, 4.10's, Nitto Dr's and skinnies up front. We have it down to 13.20's @ 102 with the stock junk 85 heads and stock 85 cam. We have a perfect set of GT40 irons and 1.7's off of a 94 cobra I have and we are going to put those heads on the 85. So now we need to pick a cam for it. I saw the Steeda #18 cam and to me the specs look perfect for the GT40 irons and the 1.7's we have, but I'm no expert. The #18 specs are: 280/286, 220/226, w/1.7's= .510/.510 on a 112 sep and 107 C-line. Steeda told me that the #18 cam was designed in the early 90's with the help from Crane (who still grinds it for them) and was designed specifically for the Gt40 irons in a GT40 package with Gt40 intake etc. Steeda said they had a 92 coupe with the #18 cam and GT40 irons and they got it down to 11.90's at 113+. The at all sounds great, but the only thing that bugs me is that I can't seem to find anyone who uses it or knows of anyone who has a screamer with that cam in it. The Steeda #19 which is the same cam except it has a wide 115 sep is real popular with the 94-95 guys with the finaicky computers, but I don't see the #18 being used by the Fox guys. Is the cam a dud or was it just not marketed a lot. I would jump on another cam, but the specs on the steeda #18 just seem ideal. Let me know what you think about a cam for our 85 project with the Gt40 irons and 1.7's. Thanks!

The #18 has only had good reviews, as far as I know. I've seen cars with it and they run fine, it'll definitely be an upgrade from the stock 1985 cam you have.

I see a lot of good comments about the TFS stage 1 cam. The stage 1 cam with 1.6 rockers specs out almost the same as the Steeda #18 with 1.7's. Stage 1: 275/279, 221/225, w/1.6's= .499/.510 on a 112 sep. The Steeda #18: 280/286, 220/226, w/1.7's=/510/.510 on a 112 sep. The steeda cam is $199 and the stage 1 is like $160. So a lot of guys use the stage 1 because it is cheap, but it still seems to like the Gt40 iron heads. You would think if the Steeda could get their notch to run 11.90's at 113 with the #18 cam in a mild N/A combo with Gt40 irons, that guys would be buying this cam up like crazy, but you hardly ever hear about it! Any idea why?

Did alot more than cam to get that car to 11.9. The TFS is cheaper and justa s good of a cam. You could also look into a Comp cam.

Maybe we should get a really good set of springs and use the Stage 1 with 1.7's. Our lift would be .528/.540, Would that lift work good with the GT40 irons or would it be wasted lift?

Both the tfs1 and the no.18 are good cams. Since you're goin to be running 1.7 rockers I say go with the tfs1 cam just because it'll net you more lift but no so much that it'll be too much for the heads. They'll be at their limit of flow at that lift but it'll be fine.

Man, you are just everywhere , aren't you. When I say "ideal" that is just my opinion. I just think it has a nice amount of @ .050" duration but timing events still maintain good cylinder pressure since we only have 9.0-1 compression. A nice additional 6 degrees on the exhaust side to help the exhaust weak iron head, enough lift (.510) with 1.7's to allow good flow but still leave us some room for possible milling. Plus, I just can't get myself to put huge amounts of lift on a head that peaks at .350-.400, maintains that flow to .500 and then starts to lose flow above that. Not to mention the spring requirements and guide wear etc. associated with high lifts. Back in the days before the high flowing alum heads, everyone was using either the stock heads or GT40 irons and you very seldom ever saw a cam company make a cam over .500 for them. Almost every cam from Crane or Crower had .480-.496 lift. I think the same thing applied when the FRPP letter cams cam out. The E, B. & F are all short lift cams. I was thinking the X & Z came out later when the GT40X and other alum heads started to come into play. I'm certainly no expert, but that is kinda how I came to my conclusion, even if it is wrong. Thanks & Take Care! Aaron

By the way that carb is probably too much for that setup.
