Reading a Cam Card: Advance A pushrod is a metal tube constructed to transfer the valve motion of a lifter riding on the camshaft directly to the value. All you have to do to determine valve lift is multiply the lobe lift times the rocker ratio. Im looking into a cam to suit small block ford. were used. The chevy part number for that cam is 3896929. A roller camshaft has the valve opened faster and remains at a higher lift for a certain time; it allows more airflow and more power, which reduces wear. The numbers on it are, 3734R/3377R, HR13, I 3996-06. While a simple call to the COMP Cams CAM HELP tech line (1-800-999-0853) and short discussion with one of the highly informed tech line personnel will always get you the right answers, having a little personal knowledge on the topic is always a good idea. This is the number of crankshaft degrees of separation between the intake and exhaust lobe center lines. There are many numbers and terms used to describe the design of the camshaft and it's important to know how these numbers will affect the performance of your engine. In this case, we dont know what the opening and closing points are although you could compare the intake lobe points to an off-the-shelf XFI RPM Hi-Lift cam and probably be pretty close. Also can i safely run the Xtreme Energy, XR294HR on my 383 Vortec 906 heads and screw studs ? item 7 1957-1963 Corvette Camshaft GM 3736098 Solid Lifter 283 Sp Hi Perf 327/340 360hp 1957-1963 Corvette Camshaft GM 3736098 Solid Lifter 283 Sp Hi Perf 327/340 360hp. I suspect you have . This figure is derived by adding the intake center line plus the exhaust center line and dividing by two. Cam is in used shape but with little to no wear. There following are ways you can tell a difference: As the name implies, these sets of numbers reveal the model of the camshaft. We continued down the list until we found the 3709 number, which because it is listed first on the camshaft, is the intake lobe. DOHC is a production to improve the volumetric of the internal combustion engine in which it has more power than a simple overhead cam. $799.00 +$36.00 shipping. Answer (1 of 4): Most common specs for an engine would be for example.
