You would definitely want to change things around if you are spraying that much nitrous.

Mark and I already had a private conversation in regards to the cam he was using and a cam I suggested. He chose to purchase a cam from someone other than me. My recommendation was based from thirty eight years of racing Pontiac engines, hundreds of standard pushrod location Edelbrock head combinations and the results from a friend of mine running a very similar combination as Marks. If Mark would like to post up his "new" cam card we could all critique it.

His original posts have merit but they are basic text book information. They are guidelines, but don't get specific on what needs to be done for specific applications and why. Chances are when you call a cam grinder to purchase a cam you will talk to a salesman that has been trained to recommend something from their catalog and also to be conservative or "safe". If your fortunate you will get to someone more than a trained salesman. That person will be helpful and usually have a lot of feedback but I doubt it will be direct feedback based on combination like Mark's. His is unique and not a ton of them like his out there.

I remember calling Comp Cams thirty some years ago and asking the gentleman that answered the phone for a recommendation. I was running a 463 with 7F6 heads, 4,000 stall and 4:10 gears.... He recommended a 268H (218/218 110 LSA .468 LIFT) cam due to the low compression. I reiterated my combination, told him this is more like a S/S combination and they were running 270° solid rollers. He said "they'd go faster with the 268 due to their compression ratio". I had similar experiences with other calls, I've also talked to some sharp guys that were and still are helpful.

That's pretty funny and not surprising from 30 years ago. How many thousands of 268H cams have been sold over those 30 years? 267-455 Pontiac V-8, fits them all!!! It's all the cam you need in a Pontiac. If you were a serious racer, you wouldn't be running one anyway. Those were the days. Throw out the 068 cam, put in the 268H Comp Cam and run about the same. That's about the time I was first introduced to Harold Brookshire, Tim Goolsby at Ultradyne/Bullet cams. Everything changed from that point forward.

Thank you for your help but the cam I got is from you a customer of yours sent me his cam card part #.I order it today .So thank you. Our combo are really close his heads flow a little better than mine .I have better lower lift #.Here is the Hydraulic Roller I just got but not using order a solid roller today Cam is new in the box.

Most of your professional engine builder have a good understanding of how cams work. Most of them have thier own grinds that they have worked out over the years. They also normally work closely with a cam company. Normally they can get you in the ball park with a grind that works with your combo.

If I am working on a new combination and I would prefer to call a engine builder and let them get a baseline cam. If I already have a baseline I will normally cam a cam company and have them help me make the changes I am looking for.

Why is it people expect professionals to give out hard earned info for free? Mark should call Paul and buy a cam from him if he wants to know what Paul would do.
Ron Walker (a customer of Pauls) has a pretty similar combo and he's running the ets Mark wants to run so Paul's been there done it.

Not so sure he was asking to spec out a cam, but pick his brain and shoot the $h!t about N2O cams. You know, from a guy "in the know" as Paul likes to say.
You think Paul designs cams ? Or call guys like Scott B and takes the credit why it runs so good. I think the latter. Give the specs to someone with Vizards program and buy the cam it tells you to. Thats what all the cool kids are doing.

I have heard good things about a cam guy at Bullet named Chris Paget (not sure on the spelling)

I buy a lot of cams from Scott, I also buy a lot of cams from Comp, Crane and Crower. I used to be a WD from Lazer and bought a bunch from him.
I'll give credit where credit is do. You should know that I've given credit for you being what you are many times. Of all the records that my combinations have set only one was done with a grind from Scott. It was a turbo 4.6 Ford. However it looks like we're going to be the first 511 cid Pontiac to break 1100hp with E-heads. That engine has a cam from Scott in it.

Usually I avoid BS'ing with the Village Idiot but since you brought it up, how about you start. Please explain to us what makes the cam your selling a good pump gas nitrous cam? I've run almost identical grinds and I wouldn't necessarily say it was a good pump gas cam or nitrous cam.... But I'm still learning.

I know who I am not calling with cam questions!
