143 Blueprint Cam Install

**kwhizz** · #1 05-14-2009, 04:54 AM

First off................Thanks to Jim and Rob for their efforts in getting these Cams made...When I built my70 Nova a couple of years ago, I just bought a Generic L-78 camshaft figuring that a Cam is a Cam.......Well.....the Nova ended up being a "Pooch".....I was dis-appointed with the power that the Engine made and it sounded pretty Tame...
Just finished installing the Blueprinted Cam purchased here.......After the cam break-in......it now Idles with a an Attitude and the throttle response is right there.....It's raining out now so I can't take it out and find out how much difference there is........Tomorrow.....LOL

Ripping it apart....

After the Install breaking the Cam in.......

Good stuff, Ken! I'm guessing you'll be the first to get some drive time on one of these GM143 cams...btw, how'd you setup the cam, straight up, advanced, retarded? Inquiring minds wanna know...

Well, guys we are hoping that the cam exceed everyone's expectations. When Rob and I discussed this thing, we asked Bullet to measure every lobe on the master cam we sent and duplicate the best lobe of the 16 lobes. We asked them to use this lobe as the master lobe for this blue printed camshaft trying to make something good even better.

For those number crunching the lobe measures [email protected] and [email protected]. The instructions on the camshaft that they use for max open spring pressure are conservative. Your instructions stated no more than 330lbs spring pressure because they want you to sleep well with minimal wear with your camshaft. Crane suggested when they made this camshaft, spring pressures of 120 closed and 310 on the open. If you are a 4 speed I would not run any less if your aggressive or race track driven. Performance range of this cam is suggested 3000 to 6400RPM. Valve float was 7000RPM with the Crane spring pressures. Remember to break the cam in with reduced spring pressure. Brad Penn oil or anybrand with the high zinc content would be smart. I hope this helps with your setup and break-in.

For the guys racing and pulling gears with standard solid lifters they do not advise more than 370lbs open pressure on the EP-2 core. With the EDM lifters, they suggest no more than 400lbs on the core. Using these high pressures, the idle should be increased so that the crank helps lube the cam at the low RPM. You must have reduced spring pressures for the breakin with this over the nose pressure from the spring.
