F or B cam for my explorer motor
- Thread starter stang2841
- Start date
I think the flow improvements that the P heads offer make them a better balenced head for intake to exhaust ratios. But not so much so that the B or F cam over the TF1 will make any appreciable difference. B or F cam will cost you $165 bucks. TF1 will cost $140.
And, for what it's worth, the TF heads (for which the TF cams were made) have very close to what is considered perfect intake to exhaust flow ratios. The TF cams still have slightly biased lifts and they work great with the well balenced TF head.
If you're doing things as low budget as possible, I fail to see why the TF1 is so summarily dismissed so easily.

If you claim to know this much already why the hell did you ask in the first place? Use the search and you can see that 90% use the f cam over the b cam, but you prob need to upgrade your valve springs with that cam.
:worthlesa
Imo I would use the crane 2031, it works well witht he p heads

crapola You asked about being better for P heads, then you stipulate that the TFS cam that was offered (the cheaper, better HP, better gas mileage, better behaved cam with an equally agressive sound that met all your requirements except being an FMS cam) wasn't designed for P heads. As stated earlier neither was the B or F cam designed for P heads, so that means you're stuck with the stock explorer cam if you want a cam designed for those heads! Just take the advice of someone who has a B cam with worked over Ford iron heads and go with the TFS Stage 1. I'm switching as soon as possible to that cam. Perhaps next time you should call the thread "which is better, B303 or F303" and leave out the head question if you're just comparing those two cams.

You just showed how much research you've done...ZERO! Ford heads need help on the exhaust side which is why most good cams are split lift\split duration favoring the exhaust, or why some guys put 1.7s on the exhaust valves with 1.6s on the intake valves.

...yet you have the F303 in your list of two cams that aren't even the greatest to begin with......I have an idea, why don't you flip a coin and pick one of those two cams your so rock solid set on....you sure as hell don't want help from us.
Cam specs:
TF1 - 112 Lobe Seperation
Int. Lift w/ 1.6:1 = .499"
Open -3 TDC
Close 38 BDC
Exh. Lift w/ 1.6:1 = .510"
Open -48 BDC
Close -4 TDC
B303/X303- 112 Lobe Seperation
Int. Lift w/ 1.6:1 = .480" - w/ 1.7:1 = .510" (X303 w/ 1.6:1 = .542")
Open -5 TDC
Close 39 BDC
Exh. Lift w/ 1.6:1 = .480" - w/ 1.7:1 = .510" (X303 w/ 1.6:1 = .542")
Open -49 BDC
Close -5 TDC
F303 - 114 Lobe Seperation
Int. Lift w/ 1.6:1 = .512"
Open -4 TDC
Close 42 BDC
Exh. Lift w/ 1.6:1 = .512"
Open -52 BDC
Close -6 TDC
The B303 and TF1 are almost the same camshaft. The only possible real difference is the ammount of lift and the shape of the lobes since the timing events are only different by a degree or two.
Also of note, I see that Summit has increased the price of the TF cams.

To note: the LSA on the E303 is actually 110*, F303 LSA is 109*, B303 LSA is107*.
IMHO, I wouldn't go under 110* LSA on a typical street motor. LSA and duration kill or build lowend, especially torque.
I also would NEVER use a single pattern cam on an SBF UNLESS testing with that PARTICULAR combo demonstrated that a single pattern cam would be better suited for THAT combo.
I'd even run a split pattern cam on aftermarket heads. If you look at the flow numbers, aftermarket heads still flow significantly less on the exhaust, and therefore could also use the help of a split pattern cam.
The TFS 1 cam is the BEST cheap cam, and can beat some more expensive cams. FMS cams are, in general POSes. I'd never go near a E or B to save my arse!
Mr. Original Poster, you are full of crapola You ask us, then you tell us...WTF kind of question is that??? Either do WTF you want or keep asking other places 'till they tell you what you want to hear!
Innterrresting! The formula makes sense, but where did you get the numbers? Summit just says LSA = 112, and so on. FRPP doesn't say anything about the LSA, anywhere. So where did the numbers come from?tjm73 said:
PS: Then I WAS quoting the advertised LSA, considering that Summit is a major advertiser. Unless you know something I don't?
PPS: Who'd you have to kill to get the valve event info?

I got the timing events for the TF cam from the TF website ( http://www.trickflow.com/product/camsandvalvetrain/track_cams/track_camsspecs.asp ) and the FRPP timing events out of the FRPP catalog on page 80.
I don't always trust information given in a Summit catalog. I've seen it wrong too many times. I try to go to the source.

I am running the tf1 cam in my gt40p headed motor and i love it. Before that I had a crane flat tappet with .512/.512 and around 234* duration. I love this trick flow cam alot more. The car pulls alot harder, is easier to drive, and the sound is so much more nastier even thought its smaller. I got mine for $80 new while searching around, but either way I was going to buy it anyways. I recommend it 100%! You will not be dissapointed
okay... nvm I found a used custom cam designed for the heads.. forget this whole thread...
I very much know the 5.0 motor and what it takes to match up a combo.. I just dislike the TFS1 cam for a few reasons... but to everybody here it was made my god himself..
.226/.232 @ .499/.499 at 111 lSA
look up on how a GT40p heads flow btw.

Have fun with your combo, but for the record people who know a thing or two were trying to help you. I don't know why you post when you just want to fight and think you know everything. I wouldn't have had a problem with your last post if you were not a smartass and said god himself made the trick flow cam, for the record trick flow made the trick flow camstang2841 said:
I know for myself i didn't know everything when i was 16, and i still don't know everything at 22, but whatever. SOOOO SORRY FOR TRYING TO HELP YOU!
