Question

Sorry if this sounds stupid but im not sure.
I bought my car with the motor already done
and the guy didnt know to many specs. im trying to find out exactly what i have. Here is the little I know . 400 block, world sportsman 2 heads, dual valve springs, push rod guide plates. I was wondering if aftermarket cams have a part # somewhere on them if so where? The guy said it was 515 lift int/exh. dont know the duration. i cant find a cam like that on comp's web site wich he said it was.Also is there a way of telling if you have forged crank or rods by looking at them .assuming the Oil pan off ,heads off?
Im also trying to figure out if this may be a
406 . I do know it runs hard !! ( eats mustangs and ram air t/a's) Thanks for any help. Also anyone going to the Woodward cruise in MI. This saturday ?

I'm not sure on the crank, get the casting #'s off it and check with a machine shop. The cam does have #'s on it. My car had been in storage since '89 when I picked it up two years ago, and the previous owner couldn't remember the valve lash (solid cam). So I pulled off the timing chain to look for the #'s, but they ended up being on the distributer side. I pulled the cam got the grind #'s and called crane cams (he knew it was a crane). They read off all specs from the cam card to me over the phone, then I was set.

From the few Comp Cams that I've seen,the # is usually stamped on the timing gear end.If you have the oil pan off,you could always pull the timing chain cover and gear to get the cam #.You could then go to Comp Cams web site,they list all thier cam cards on thier web site,but you need the # of coarse.

You can tell a cast from a forged crank at a glance. A cast crank has a sharp parting line, the parting line on a forged crank is flat, almost a hald inch wide

Try looking at the front of the flywheel flange.
Where did the guy buy the cam? Maybe you can get them to look up the reciept and make you a copy. It should list the cam # there.
