Bill, install the TFS cam with 4* advance for your combo.

I presently own a TFS-1 CAM and I’m rebuilding my motor as some of you know the question is I could get an E-CAM for nothing. Might it be a better cam for what I’m doing my basic set-up is going to be stock E7 rotating assembly GT40 iron heads 10.1 compression GT40 explorer intake 70mm TB and mass air. I know most would say the TFS-1 is a no-brainer and I agree but what I’m wondering since the I could get the cam for free and the mostly stock ford build might I see the E-cam being better for me.

I know the TFS-1 cam comes on at 2000 rpm, when does the E-cam come on this might help my decision since I’m probably going w/a 2800 stall converter.

If you can get it for free try them both. Your combo may respond differently on the track or street depending on which you choose. You also could have a personal preference on the cam, how it performs or how it idles. The only way to know for certain is to try it. Then you really know.

Thanks for your help guys I guess ill stay w/the TFS-1 cam. I think I heard that some where too that the TFS-1 cam is a modified E-cam. I also heard 2 things about trick flow 1 there copycats which makes sense w/above said. And 2nd that there the old SVO which also makes sense w/above said. I also was told some where the letter cams are good for the time but its 80s technology and things have far come since then.
Just had to ask since I could get a free e-cam but ill let it go.

Paul putting the cam 4* advance would give me more lower end power correct. Don’t know if I want the since these motors are naturally torque happy I’m thinking more top end but I don’t know. I should ask my motor guy.

P.S I also heard that summit owns trick flow now this might old news to some of you but I figured I repeat it for those who don’t Know cause when you buy a summit part it’s the same as trick flow w/out the name.

With the GT-40's that cam won't realize it's full potential up high (6000 RPM) unless you port them. You'll also want a convertor that stalls around 2600 or more if you go straight up with it. Also take note of your AOD tailshaft governor and what your RPM's are at WOT. I can't remember if you have modified your transmission as of yet. I would recommend it highly if you have not done so.

By advancing 4* you'll gain the low end grunt and you won't notice any difference up high. Peak torque on a TFS-1 cam is around 35-3800 RPM depending on the supporting engine parts (heads, intake, etc.)
