[SVT] "I don't have my FMS catalog in
front of me but, I'm using the B303 in a FMS crate engine
(M-6007-XB3) rated @ 345HP. The same engine with the E303 is rated @
340hp. I think the power band for a E303 is wider (2500-5200 rpm)
than the B303 (3500-5000) rpm. I'm just beginning my build, so I
won't know how it runs for a few months. FWIW the FMS tech guys feel
this is "the" cam for a FFR project just because of the
lope sound and the fact that the vehicle doesn't need as much low
end torque due to the low weight.
There are a few posts about the "E" vs "B" on
the http://www.corral.net
and the http://www.stangnet.com"
[CD] "B cam fair idle good low end torque
significant top end hp above 4000 rpms 5 speed recommended peak rpm torque
3300
hp 5100
E cam good idle quality excellent low and mid
range power above 2500rpm. Power through 6000 rpm emission legal
with 5 sp works good with auto also great for superchargers peak rpm
torque 2500 hp 5500
Engines with with B cam show slight inc in HP
( 5)"
Which Cam for Explorer Engine?
[HP] "I will be picking up a new gt40
explorer engine this weekend. Plans are to use the trick flow 2000
cam, 1.6 rockers and 24# injectors."
[MI] "I have the GT40-P heads (explorer take
offs) and the "F" cam. Love the lope sound.
I do not know how this would work on an EFI
motor but on my Carb it is great.
Gordon did the porting of the heads.
The motor pulls strong up to my imposed 6000
rev limiter and it wants to pull even higher."
[AU] "I used a trick flow cam because it
was cheep and it is a split pattern cam with more lift and duration
on the exhaust. I have read that a Carb motor likes this but a F.I.
motor likes a single pattern cam like the Ford ABC cams."
