Title says is...Wondering if you can get this info if cam is already in running engine. Engine had cam replaced during rebuilt but that was before I got the engine. Any help appreciated. Thanks- Claude
You can if you have a degree wheel and dial gauge setup. It depends on how accurate you need to be but you can get pretty damn close. You will need to find TDC with the degree wheel and you can use a piston stop for that. You will use the gauge setup to measure the cam. I would just pull the rockers (or a rocker) and place the gauge on the top of the pushrod starting on the base circle.Title says is...Wondering if you can get this info if cam is already in running engine.

print yourself a degree wheel (https://static.summitracing.com/global/images/prod/large/SUM-G1057.jpg , https://lh3.googleusercontent.com/p...tvXvC-4SbPAxeiDqIxZwa1WHVBldBK4MaRiwp42TXM3HW) and glue it onto an old Nickleback album. Use piston stop and find TDC and set it. Use a dial indicator on a pushrod (dont use on a rocker as the spring could 'deform' the lift due to hydraulic lifter preload). Your lift will be pretty close to dead nuts by using a 1.5:1 ratio and then you can determine the duration by TDC and lift @ .050 per a cams spec. Use a intake and exhaust to see if its a split duration cam.
Here's a great video to show you how.Title says is...Wondering if you can get this info if cam is already in running engine. Engine had cam replaced during rebuilt but that was before I got the engine. Any help appreciated. Thanks- Claude
