So I hope I'm in the proper place to post this Has anyone run a Schneider S-100 cam in there flathead,I'm building a .060 over 239 with 1.5 & 1.6 Manley Pro Flo valves ,milled Offy 400 heads ,Vertex mag ,ported intake ,exhaust and 4 Holley 94 carbs it's a light car with 4:11 Halibrand quick change. It's going to be a red light bandit and an ice scream runner. I have been building it to be a late 40's early 50's hot rod. I have a 270-f Schneider cam for it but have question if it's big enough for the carb setup. I'm open for suggestion. Thanks Sent from my iPad using The H.A.M.B. mobile app
I think the real question is whether you have enough cubic inches for what you're doing? Your setup mentions 4 carbs on a 248 cubic in engine - I'd guess it would run a lot better with two of them, though you might get away with 3. I'd say the 270-f Schneider cam should be big enough - but you're probably quite a bit over carbed.
I agree with Bored and Stroked. I had a much bigger stroker that ran great on a 2 pot. As for a cam dont go too big. Maybe Pete1 can chime in here, but there is nothing worse than an over cammed motor. Check out the specs on an old 1007B grind. That is what was recommended for mine by Pete and it was an awesome street cam. I think something similar to that would work well for you too. Remember Flatheads are not top end screamers. You'll do much better overall and enjoy the driveablity with a streetable cam that has a strong low and midrange IMO
Yes - the 1007B is a great cam for an engine this size . . . Pete and I are definitely 'in sync' on that opinion (and most others, we've worked together on flathead projects and Bonneville for quite a few years). D
My pops is running a 270 in his 28 roadster. two carbs, alum. heads. Runs real nice and has a great lope ay idle.
It would be real simple to pick up the phone and call Jerry Cantrell at Schneider Cams and ask him which cam he would recommend. Whenever someone orders a cam, Jerry asks lots of questions to make sure the cam you select will fit your application. So why take the opinions of other well meaning but not necessarily informed bystanders when 1 phone call will settle it? (619) 297-0227
Here is what that 1007-B sounded like in my 286 stroker. It was so fun to drive, it pulled like crazy from just off idle to well up in the RPM's . It was the perfect street cam for my car.. I'm not sure what the specs are for the 270 but I'd trust Bored and Stroked or Petes cam choice as Gospel.
Hi Deucemac Jerry and I go back to the early 70's and I have always trusted him but for the life of me for all the engines I have built this cam just seems small. Of course everyone tells me these are a different breed of engine and I now I should just trust Jerry . But that S-100 looks more like what I would want and I want to build this engine once and not have to take it apart if it's not what I want. Thanks for the info Pete
Your car looks and sounds awesome. Is there any mufflers or are you running straight pipes because I love the way it sounds . I also love the color I'm new here but I will try to upload a picture of mine Thanks for the help Pete
Thanks, Yes they are just 2 1/4" straight pipes with no mufflers. Your Coupe looks awesome! I agree calling Schneider would be wise. I got my cam advice from Pete1 on here. He's been grinding cams since before most of us were born I think. He was dead on. I'm sure Schneider wouldn't lead you wrong either. I think most people tend to over-cam flatheads not understanding they just wont turn high rpms no matter how badly you want them to, and miss the low/midrange potential they do have.
Hey Rusty Rocket Would you know or could you find out what kind of vacuum your fathers car makes at idle. If I knew it would make the power valve selection close initially. Thanks Pete Sent from my iPad using The H.A.M.B. mobile app
I know some may disagree, but: I run a Potvin 425 "Eliminator" in a 290 inch Flathead. The car is a 32 Tudor Sedan. Everyone I ever talked to, Except Pete, said that'll never behave on the street. Well, it's about the best cam you could ever want; 12 inches vacuum @ 900 rpm idle, pulls smartly from 1200 rpm up to 5500. Large intake valves (1.72"), center dump headers, dual 4 bbl carbs, Pertronix converted Helmet distributor. Stock C7RA Aluminum Canadian heads.
I would totally be happy with an engine that ran in that range. And I'm sure it must sound great. I never saw a 2-4 barrel manifold What carbs are on it? Thanks for the info. Pete Sent from my iPad using The H.A.M.B. mobile app
Pete, You and I all agree on this! I ran on original 425 in my 284 cube flathead on the street - with three Holley 2110 carbs, heavily ported, aluminum flywheel, 25T Zephyr gears . . . ran really well! It is a fantastic cam. I prefer to have it ground on a 32 Steel core (which is what Potvin typically did), but that is just me.
Tomorrow my buddy Jerry at Schneider have to have a discussion on this cam situation. I think the S-100 with 270/280 duration is more what I'm looking for. I didn't stroke the engine so it would rev more safely but because of the small displacement it needs to rev to at least 5000 plus with the four carbs I need to increase the clyinder fill time. The engine has an aluminum flywheel and the car has 4:11 gears so it should have good bottom end. So we will talk ,I have got to say that Jerry has done all my cams since the early 70's and Dave did my cams before Jerry. But I have to say they never were wrong with the cam selection.
My only concern would be the 4 carbs running direct linkage. My small 2 X 4's are vacuum secondaries. I have no idea how far they open under WOT. Never checked Jim
You REALLY should talk to @Pete1 but I don't think he lurks the HAMB anymore. If you want, I can pm you an email and I think I have his work phone number.
I started using Schneider in 1965, my senior year in high school. Dave managed to steal Jerry away from Crower in around '69 or '70 I think. At one time Dave ground just about every cam used at Indy. They did all the Offy stuff and still have the best cams for my money.
I have been crazy with work but I home today so we will chat . Thanks Sent from my iPad using The H.A.M.B. mobile app
So I talked to Jerry at Schneider cams and he assured me that the 270-F was the cam for my engine combo. We went over everything I have done to the engine and the car setup with the rear end gears and he promised me that a I would love it. Like I said he has ground a couple of hundred cams for me over the years and has never been wrong. So it's going in. Hopefully in the next month I will be done with it and it will run. I'll keep everyone posted. Thanks to all for your input. Sent from my iPad using The H.A.M.B. mobile app
Hey Pete F - so I just have to ask the question . . . if Jerry has ground a couple hundred cams for you, and never been wrong . . . then were you expecting us all to change your opinion on him and what he'd previously recommended to you? I don't get it . . .
That's a good question For some reason I thought he was being conservative in the grind. And with no experience with flatheads I have read tons of blogs and everyone's opinion as to what works is all over the board so I questioned the combo. If you came to me with an overhead valve engine I could give you my opinion from experience but since I never build one of these crazy flatheads I looked to read as much as I could and man nobody agrees on to much. Hey I was only asking to learn not trying to cause any confusion. And one last thing this my site ,I build anything from race engines to Duesenberg engines so it's not like I'm trying to BS anybody just trying to gather info.

No big deal - this site is ALL about asking questions and sharing . . . was just wondering where you were coming from. When one is new to flatheads, you soon find out that there are more dang opinions on these old boiler makers than just about any dang engine. Many of the opinions are not from experience and trial and error - but have been passed down over the ages, written in articles, etc.. I've been building these goofy engines for 40 years - and I'm still trying new things all the time . . . in some cases because I like to try new technology (coatings, etc), other times to just try something out of curiosity. There are many ways to skin these cats - and many different applications - it seems endless the amount of opinions that go along with that. There are some really experienced guys on this site and over on the Fordbarn. You'll soon figure out who to listen to on what . . . or, make up your own opinion along the way. One thing for sure, you'll rarely get two cam grinders to agree on anything -- especially if you ask them if their competitors Grind XXX is any good! Keep the posts coming . . .
Ran a 268 8ba... the boys in the GE tool room fabbed up a couple alum. spacers / adaptors that let me run 60's + 70's ford two barrels, i thought it ran great... carbs were easy to find... very cheap... but the look of the 94's and velocity stacks won out... less pop but a better profile. IMO...if not at the strip... run what you like the looks of as you are the one who's gonna be looking at it...
After being in the hot rod and race engine business my whole of flathead people sure swing 180 degrees on what works. Engine people as a rule may not agree totally on things but they are usually in the same park. And as simple as that silly flathead is the only thing everybody agrees on is that center exhaust port and that is where the power is robbed but not to many people agree on how to get the power. So I far as I go it's not going to be a race car just build it to sound cool and enjoy it. If you want to see a complicated engine go to my site and look at the supercharged Duesenberg engines I have built under past builds. 1200 pounds of 8 cylinder power, 430 CID and over 420 horsepower out of a 1930's engine. And as cool as they are I would just like to build a nice normal Chevy,Mopar or Ford.
