Gt40 Combo With 1.72 Rockers

Comp cams 320 open 135 on the seat. Most ots new other than a b303 were within 30-40 dollars of a custom. I plan to upgrade to afr heads when money is better. Haven't found any used cams worth picking up and not knowing If that's a good option, one lobe messed up could grenade my motor no?


Used roller cams are fine. They don't wear near as much as flat tappet cams and any damage or wear they might have will easily be noticeable during a visual inspection.

I just picked up my CompCams XE274HR for $175 with only 5,000-miles on it. That's about the high side of average for a decent used off the shelf grind and the used Motorsport cams are going for less than that.

I dunno...personally, I think custom grinds are reserved for the guys who do class racing that need to stay within certain parameters and not for your average joe just looking to pick up some useable street power.

Again, it’s your money to spend, but I’ll almost guarantee you that any power or drivability you do pick up with a custom bump stick won’t be noticeable on anything else other than a dyno sheet. Of course....the guy trying to sell you the custom grind isn't going to tell you that. ;)

The reason I went with a custom cam was so it could be matched to the motor and the gearing.. Like the op said its only 30$ more for the custom compared to a new comp cam..to me it's worth the 30$ to have it matched as closely as possible...that way I know nothing is left on the table.. If I could find one of the off the shelf used cams for less than 200$ than I would prob do that..
 
I considered used cams but the options before me seemed not worth the asking price, not to mention asking for pictures was like pulling teeth, no way I'd pay 125-150 for a used b303 or 210+ shipping for a 2031 both are older designs. Hit up a guy on a used n-21 never got back to me. So new was looking like my only option. To me the extra 30 over a comp or Anderson cam is piece of mind. Even if my combo is nothing special ill be getting the knowledge of a cam pro and the most up to date technology in what is essentially the brain of the motor.

I guess it all depends on your perspective. Try not to take this the wrong way, but you seem concerned with leaving horsepower on the table with cam selection, yet not so much when it came to selecting the rest of your parts. Your 65mm throttle body for example. Why pony up the expense of a 3.5" intake tube, when your throttle body inlet is only a little over 2.5"? Why limit yourself with a Typhoon intake when you're running 190cc heads? Why go with shorty headers when long tube are proven to make more power and torque across the entire RPM range? Why pony up the bucks for a brand new custom grind cam, only to fill the rest of the order with mediocre, parts? :shrug:

Understand, I'm not trying to stomp on your toes here and am sure you're very happy with what you've got, but I see a lot of "priorities" of convenience when people put together their combo's all of the time. Spending all kinds of time and money on one area, only to skimp in another.

Before you get mad, understand at this point I'm no different. Hell, I've got a high compression 331ci stroker, sitting on the stand right now with a set of GT40X heads and Explorer intake ready to bolt on. Not exactly optimal for making horsepower...but I've always had performance on a budget in mind when building my combo. I mean....I could have gone the custom cam route, but why when there are so many great OTS grinds available on the used market and the rest of my combination of parts leaves so much on the table anyway?

I'm noticing a recent trend. People have been falsely led to believe that unless is a "custom grind" you're going to be left unsatisfied with performance. When in reality....99% of us out there couldn't tell the difference. We're not living in the early-90's anymore when there were only about 6-8 off the shelf street friendly cam grinds to choose from. There are literally dozens upon dozens of varying camshafts out there today to fit all walks of life. So much so that I question anyone’s need for custom cam profiles in a daily driver.

One other thing to consider...that custom cam grind may seem like the cat's meow right now....and might very well be provided you leave the rest of the parts on the engine that it was ground for. But let's be honest....we're gear heads. We're never satisfied. Before you know it, you'll be changing heads, intake, exhaust components again and that more expensive "custom" bump stick that worked so well for your previous combination is now in the same boat as the rest of them.

If that additional $30 (or $100-$150 depending on whether or not a good used cam is available) you're paying buys you piece of mind, then I guess it's worth it and no amount of text I type here is going to change your line of reasoning. Just as long as you're aware of it. I on the other hand am just fine with picking up a comparable unit at a local swap meet and still have enough money left over for new lifters and timing chain to go with it for what you paid for your cam alone. :shrug:

You just need to broaden your search area. They're out there. PM sent.

ok, from your point of view this makes sense. the reason i went with the 3.5 inch tube is because i needed it that big so the meter does not peg, a 3 inch tube wouldnt have given me enough to grow. it cost me less than 50$ for the tube, weld on bung and sensor. the setup i have at the moment wasnt supposed to be the way it is now. i originally bought the heads for a 351. that turned into spending more money than i wanted to spend. so the heads went on the 302 instead of sitting on my bench. the typhoon was a better option than the explorer intake i took off when i put the heads on. the shorty headers were on the car when i bought it so they didnt cost me anything. so i posted a thread on here and everyone was saying get a custom grind because of the mismatched setup. i have a 70mm throttle body i could put on, but i will need to buy a different intake adapter to put it on. but i do agree with what you are saying..i just didnt want parts collecting dust on my bench if i could put them on my car and gain 50 hp.
 
Another thing you buy for that $30 is the open advice of someone who really knows his stuff. I've had 2 FTI cams. The first was in a 302 that made 320rwhp, which is right up there with the best Cobra intaked street combos and it was a really mild 22x's duration cam. Could I have done as well with an OTS cam? doubtful. At the time, I didn't know a whole lot about these cars and took Ed's advice. He helped me select the right parts to compliment my combo (already had the intake). Then he actually helped me with the installation over the phone. That was about 10 years ago, and I'm still happy with the service he provided.
 
Ed's been a pleasure to deal with, and I like his no bs approach. I changed spring rates, ordering some fuel system upgrades before the cam arrives...pretty eager to see the results
 
Not knocking the trade, but I dislike no brain custom cam nut riders that'll recommend custom over ots grind to someone who just have gt40 top end. Sure, for race applications I can see it. I mean, if you change anything on the car, then you will have to throw it away with that mentality. How can you sell someone a used custom cam tailored exactly to your car?

Even if the roller lobes are OK, what about the bearing surfaces?
Any damage to the bearing surfaces will be made immediately apparent at first glance. Remember, bearing material is much softer than cam steel so any damage to those area's are going to come from foreign material circulating in the oil, or a lack of it and would be quite evident during visual inspection.
 
How did you guys even get in contact with Ed Curtis? I tried to get a cam from him last year and never did get a response. I filled out cam order form and e-mailed several times over a month's period. Never heard a peep.

Emailed him.. He got back to me right away. Had the cam ordered within 3 days using PayPal for an extra 10$..
 
Just received my cam, looking at the specs it looks like it should really wake my car up. Looks a bit more aggressive than the ots cams I had to choose from with my 1.72 rockers so I can't wait to put it in, just a couple little odds and ends to buy...
 
Figured I'd update even though threads gettin old, between moving and other unexpected expenses I've finally got to getting the cam in and a t5z in place of my previous wc t5. Should be picking it up today or tomorrow. Will post details soon as I get the keys back in my hands
