Does anyone know the exact specs of the MT10 cam?? I want to compare it to the Comp 270H. I think the MT15 might be a bit big for my combo and am starting to lean towards the smaller cams.

Thanks

Looks like we`re in the same boat, wouldn`t you like to know how acaciaavenue got his 450hps too?

Btw; here`s a link to MTS-data:

I saw that but it gives a "range" of what the specs could be . I would like to see the advertised duration/at .050/lift/lobe sep angle that comes on the cam card.

I called Comp cams today to get some info from them and what a joke. The guy did not ask me anything about my combo! No vehicle weight/gears/comp ratio/exhaust/converter....all he asked is if it was FI??? He told me to get the 268H.......I said thanks for nothing !

I thought that the specs on the website was a range of where the specs could be not the exact specs on the cam.

I believe that a dual pattern cam. So one number is intake and the other is exhaust.
Advertised Duration Range: 270-285
Duration @ .050 Range: 220-228
Valve Lift Range: .525"- .538"

So the 1st numeber is intake and the second is exhaust. (I think)

If you look at the Comp cams specs (Cadillac cams)they are single pattern, so intake and exhaust lift and duration are the same, and the MTS grinds are dual pattern. Look at the Comp 265DEH and 268H for BBC. The 268H has teh same intake/exhaust lobe shape, while the 265DEH has different lobe shape on the intake and exhaust.

The specs listed on the catalog say something like "duration range 218-225" I just assume that means 218I/225E, but the way its worded is very vague.

I understand the reasoning behind keeping cam specs tight-lipped, but it is frustrating.

Some of the spec sure, but lift and duration are only part of the equation. LSA would be niice, without giving away the exact opening point (whiuch can be changed anyway).

I I though the shape of the lobe was important, more so thant the raw numbers. You can have 2 cames with the same lift and duration @ 50, but different shapes and get different performance. Ho long at max lift? How fast does it open or close?

When I read "range" that to me means its somewhere in that ballpark. Not the exact specs. Here is an example. The MT15 cam on the website says a range of 230 to 238 and lift of 550 to 560. Well , I got the specs on the MT15 and its 230/236 with 562 lift. Not the same ..........

We talking Cams or Chicks here? :lol:

Ron,
Get one custom ground for your application. I think you will be better off in the long run.

Are custom grinds a lot more expensive though.

Crane sells five different dual pattern cams worth looking at.

You probably didn't word anything about any custom equipment, and in which case, they figure you will run it as stock, and that is their slightly better than stock cam.

I've rarely had to call them, because at work, we work out the combos ourselves, but on the occasion we have a strange engine, we get plenty of help off them.

Not alot more. Sometimes they are the same price. The CNC equipment used to make them is advanced now a days, and they can change specs easily. Sometimes they will charge you for grinding something that isn't on the shelf, but they won't charge you too much.

OK. I just saw on CB7 somone had a custom regrind done for $45.
Time to get current. I remember custom cams being like twice the price of the standard grinds. And it being cheaper to buy a new cam than regrind an old one.

Horray for progress.
