need to get hold of a couple of them for motors going together, and I'm trying to see if anyone has them. Or a used stock cam so that I can get dimensions to make my own.

I'll sell you one.. Made from 9310 tool steel. 425.00
These are made for my roller program, so the lobes are a different width due to the method that we use to install the lifters. Elgin only grinds cast cam blanks, same with web. Pauter didn't have any TIV blanks last time I checked. The roller lifter TIV development took me almost 4 years to perfect, lots of challenges and conventional approaches didn't hold up well for me. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.rdtlabs.com-1095-1287018061.1.jpg) This is the set up that didn't work well... (IMG:http://www.914world.com/bbs2/uploads_offsite/www.rdtlabs.com-1095-1287018062.2.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/www.rdtlabs.com-1095-1287018063.3.jpg) QUOTE unless you want/ or need to turn the engine in the 8500-to 10,000 rpm range, NOPE... This is a roller cam dyno plot from my 20,000 mile test engine.. I drove this car all summer at 10:1 CR with the very mild roller cam I designed in 2007, running air conditioning.. Averages 31 MPG, pulls from 1,000 RPM under full load.. You won't do that without a roller cam. (IMG:http://www.914world.com/bbs2/uploads_offsite/images.thesamba.com-1095-1287018838.1.jpg) And here are the chassis dyno plots from the same engine at 15K miles.. Note that the engine pulls a set of 5,000 pound rollers under full load in 4th gear.
