How can I measure the lift and duration of a cam that I bought at a swap meet a year ago?
It's supposed to be a b303 cam and the lift at the valve I got when I measured it with dial calipers and multiplied by 1.6 and 1.7(rocker arms ratio) came out to be .3792"/.3968 @ 1.6 and .4029"/.4216" @ 1.7.
Does this make sense?
I think I was screwed out of $15.00
It came in a box that said M-6250-B303 SVO camshaft.
ALSO, the guy said he wasn't sure what it was as he was selling it for a friend.
WHAT cam do I have? I know it's a roller as it has the wide flat ramps as compared to the other cams I looked at.
Just behind the dizzy gear on it is an A and three dots.
If anyone knows what I have, any info would be greatly appreciated.

You can't accurately measure a cam with dial calipers.
You need to use a dial indicator and roll the cam.------------------

How can the cam be held accurately in one spot while being rolled? Is there a fixture or something for this?

You can get pretty close on a flat bench.------------------

I guess I can put the cam and a couple of lifters in my block and measure it that way.

When checking cam lift with a hyraulic lifter, place the tip ont he dial indicator on the edge of the lifter, not the center of the plunger.
This will give you an accurate reading.------------------

The specs I got when I did the above were: .2370" intake and .2450" exhaust.
I also checked the cam that was in the block when I pulled it out of the Lincoln Town Car and it came out to be: .2375" intake and .2475" exhaust.

Thanks Alex. I knew it was too good to be true when I saw it but figured what the heck, I had some $$ to play around with and saw a lot of stuff at the swap meet but nothing that caught my attention, save for this cam.
The swapmeet is every year in april? at the portland expo in portland oregon.
Maybe I'll go as a seller this year and sell some of my chevy stuff for the $$ to finish my 302,hehehe.

There's a place called Delta Cams in Tacoma that will grind you a hyd. roller camshaft for about $80, as I recall. You can get whatever ramp profile you want (that they have available) for the same price, and you can get it in whatever LSA you want. Only thing is, the cam is a regrind. I have bought 3 from them- one hyd. flat, one solid flat, and one hyd. roller- all are great quality and I have had zero problems. Search the yellow pages or the internet for their phone#.

Thanks for the suggestion, Kyle.
Its Delta Camshaft Inc. and I will call them in a few days using their 1-800 #
What is the life expectancy of any reground cam vs a new cam?
My combination is as follows:'87 302 overbored .030" # L2482F speed pro pistons, 9.2:1 cr. with the E7TE heads listed below stock rods with arp wave loc rod bolts crank reground to .010 undersize on rods and mains '87 stock heads slightly ported (e.g. smog ports ground flush on exhaust, cleanup of the bowls, minimizing of the valve stem protrusions,and intake port matching) '88 factory exhaust headers and 4 cat H-pipe This will be going into my 1982 mustang with a T5 trans and 7.5" 3.27 geared rear I'm open to camshaft suggestions that will maximize my fuel mileage and give me decent (13/14 sec) times in the 1/4
