cam question

Post #1 by woodbutcher » Sun Mar 24, 2013 2:43 pm

:hmmm: When I built the 302 in my 74 F100,(about 1986)I installed a cam with the following specs as best that I remember.288* duration..460 lift.Lobe separation(IIRC)was 110 or 112*.How would these specs work for a daily driver with the 300.Just a solid pretty much stock rebuild doing the required machine work to get every thing to spec,with the possibility of a 2150 carb on an Offy manifold with FI exhaust manifolds.2 into 1 setup.Just doing some pondering here.Thanks.
Good luck.Have fun.Be safe.

I'm assuming that is the advertised duration figure. That is a lot of cam for a street driven 302. I think at 50 ci per cylinder it would work on a 300 but the top end gain will be at the expense of some bottom end torque (duh!). It would be a good piece for a street/strip truck me thinks.

If that 288 is at .050 lift then it is wilder than the cams in my drag car.

Yes, 288 degrees advertised duration too much for what your looking for. Be more like 260-270 max. You will find most of your streetable Cams for the 300 six, will be in that range

That 288 number has to be a advertised duration number.
Which just like advertising "a big unknown"

Crane was usually quite consistane on it's advertised numbers,
But in the late 80's got so fed up with what other companys
Were doing decided to fight fire with fire.
They had 2 different part numbers, 2 different boxes and 2 different descriptions for
1 profile! The Fireball 290 II and the energizer 272
Were EXACTY the same lobe profile.
Same lift, same duration @ .050 tappet lift.
Both would idle fine in a car with a stock torque converter.

:beer: Hi all thanks for the replies.That cam was purchased from P.A.W. when I rebuilt the 302,and the 288* was at .050.I sort of suspected that that was a more or less midrange cam.
What happened was that I mis ordered,and got the wrong cam.It did run pretty good with NO noticeable "lope"ever.The 302 was punched .030 and used flattop Badger pistons from P.A.W.
And just a little nostalgia here,that set of Badger pistons with rings cost at the time including shipping was---------------------$110.00.Cali to Tn.Total time from sending the order to recieving
the order was just 10 days.Like I said in the initial post I was just doing some pondering.

Good luck.Have fun.Be safe.

WOW! The Crane roller I'm using in my altered has .050 numbers of 280 / 284. And it is designed for 5500 - 7500 RPM operating range.

:D Hi FTF.That cam/lifters and springs was a P.A.W."store brand"cam kit.Don`t know who made it for them.IIRC,that kit was about $85.00 shipped.Thanks for the reply.The engine ran really well
and plenty of power(for me anyway)in all RPM ranges.When I got rid of the truck,the guy that bought it put the engine in a dirt track car and said that it ran like "the devil was chewing on the rear end".Meaning it ran really well.
Good luck.Have fun.Be safe.
