Cam Upgrade comparison....
 

Wondering if anyone has any first hand experience or knowledge of which cam application might better suit my build. Twin GEN VI 454 MAG/MPI's, keeping the fuel injection, not interested in going carburation.

The Teague BBC GEN V-VI Billet stage 1 : Advertised duration 288/296 .50degrees 226/234 LSA 112 587/610 Gross lift
Comp Cams BBC GEN VI HYD ROLL " " 283/290 .50degrees 223/230 LSA 114 566/575 Gross

Staying with the factory bore & stroke, factory forged internals all stock, doing a 3 angle valve job and matching springs for which ever cam I select, adding roller rockers. Re-plumbing the fuel system removing the VST and manual pump assembly adding full electric fuel systems with adjustable fuel pressure regulators and having the ecms reprogrammed for the new fuel and air flow upgrades

Any opinions?

if your thinking of the teague cam,,just get the crane 731 20yr old tech cam that works.:D

I'd go option 1 but that's just me however a proven cam time and time again.

Aren't they pretty much the same?

I've never confirmed timing events btwn teagues version and 731 however I would imagine they are very simlilar. One nice thing with Teague is they would likely assist with fuel/ecm etc.

731: (168731)

Basic Operating RPM Range: 1,600-5,600

Intake Duration at 050 inch Lift: 226

Exhaust Duration at 050 inch Lift: 236

Duration at 050 inch Lift: 226 int./236 exh.

Advertised Intake Duration: 288

Advertised Exhaust Duration: 298

Advertised Duration: 288 int./298 exh.

Intake Valve Lift with Factory Rocker Arm Ratio: 0.587 in.

Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.610 in.

Valve Lift with Factory Rocker Arm Ratio: 0.587 int./0.610 exh
.
Lobe Separation (degrees): 112

the teague cam is a crane 168731 cam.

The answer will be given by whomever is doing your computer programming.

Two deg less exhaust duration yet Teague advertises 2,500-6,000 WHAT???

What exhaust are you using?

The Teague BBC GEN V


And you do what for a living? Boat mechanic?

Haven't figured that out yet, obviously that'll be the last installed component. Love to go a true pipe but realistically will go with two sets of Power-flows.... Have not had any good experiences with used stuff, but I might take a chance on some fresh water CMI's....

[QUOTE=GETTINBYE;4541309]Yes...

If he is a boat mechanic that doesn't necessarily mean they have first hand knowledge of drifting off into the aftermarket good guy parts. just thinking about our local marinas and mechanics here in the NW MI... unless it's in the parts book.... out to lunch! Anyway not trying to start anything over it but I even have relation who is a boat mechanic and is very sharp but just simply not real gearhead savvy. Like MT mentioned what exhaust and I know where he's going with that but let the OP answer. I have a feeling stock cast wet exh. Maybe be safer with the 114?

getrdunn,look at the advertised duration,exactly same as the 731,so bob teague fudges the numbers for two deg and calls it his own,and he is not the only one doing it.

:cheer::sport009:

My dad was a boat mechanic and a damn good one, and owned two shops that I also worked at as a teen. As you all can tell I still don't know jack **** about the performance boat sector and neither did he.

Without a doubt, teague copied cranes designs. You'll see in teagues product description, says they are made by "andrews products". Andrews products appears to be a company that you can send in a design, or a camshaft, and they can duplicate it for you. My guess, is probably at a much cheaper cost than Teague can get them from Crane direct for, which in turn, means more profit. He probably found the crane grinds worked, and wanted to offer them to customers, but wanted to make some more $$ in camshaft sales. As you'll see by comparison, except for the stage 1 having 2 more deg of exhaust duration, the rest are identical. Advertised, .050, and lobe lift. Identical.

Yeah I kinda thought Teague might be doing that given some earlier posts. Crane it is.

My Teague cams came direct from Andrews. I went with the 230/236 .598/.610 lift by their recommendation. I couldn't be happier with them.

Would it be worth it to buy from Teague just for the extra support value?

I bought a 731 cam earlier this year. Its a popular cam, Think I got on fb powerboat swap shop, new, in box from somebody who bought it and never used it. look around, you can save yourself a couple hundred.

FYI with those cams, some say they will work with stock lifters some say they wont. I took no chances and got some crane lifters. New lifters on a new cam is usually a nice thing too....

the 168731 cam is available from walmart too

https://www.walmart.com/ip/Crane-Hyd...8731/100022644

Since when does Walmart sell Performance parts........? Not the best price though, I'd rather pay more and not support Walmart.

Got one boxed up ready to ship. About 90 hrs on it, in perfect condition

THX ! I'll keep that in mind, if you had two with 90 hours on them I'd go for it.

168731?

Oops sorry I have a 791, posted before coffee..carry on

When my cams arrived I was expecting them to be Crane's. To my surprise they were the in plain white boxes no name or anything. The cam card was just printed on a scrap piece of paper but it had all the #'s. I had a few questions regarding the degreeing procedure so I called up Teague. It was after hours for them but I was connected with Bob. He answered all my questions and walked me through the procedure FWIW.

Cam still available? Btw your inbox is full.

What constitutes a "copy" of a profile could be debated. Profiles can match duration at two lifts and max lift, yet not be a copy. Maybe that's too much "Inside Baseball", but I wanted to point that out.

Andrews is a leader in the industry. As noted above, they sell software that many other organizations in the industry use to generate cam profile data. They wouldn't have a need to copy somebody's profile, but could certainly match duration and lift specs if they wanted to.

Crane isn't a standalone entity anymore. Their portfolio was purchased by Comp Cams sometime after 2010. The decision Teague made to change suppliers could have been due to parts availability rather than cost. Since Andrews is in the Chicago area, I'd be surprised if their costs of production beat what Comp could do out of Memphis, TN.

Cams
 

any competent builder with a cam doctor can copy a known to be great cam ... just sayin

Said measurement data needs to be matched with proper cam design software by a skilled engineer before it can be used to grind a cam in a CNC grinder. Even the best measurement data contains measurement errors that need to be factored out before the design is useful.
