Its great that the aftermarket has stepped up and offers components to make a big cam street able, but stuff like brake vacuum issues and being able to run the AC at a red light, idling in traffic, lead me to the build on the Camaro. The first thing I told Tim at Bullet was, I have to have 16" of vacuum, no exceptions. Second was a conversation about the D&A 409 that made table top flat torque from off idle and carried the TQ way up the RPM range. We agreed that the LSA would have to stay tight to do what they had accomplished. We went over a few different lift and duration choices and what they gave or took away from drive ability, power, idle quality, etc. Good valve train stability was important so I had to have really good springs. To keep the high vacuum I needed, we had to keep the duration short and find all the area under the curve we could get, to move enough air to make power. He picked a very aggressive lobe that is asymmetrical, that would stuff maximum air in the short duration and pushed the lift numbers as high as he could and be stable with the duration we were working with. In the end, the cam choice was spot on, giving the vacuum I needed, being stable to 7000rpms, and making more power than either one of us expected. I had done the research on the Australian baby cam, LS3 head theory and he agreed that the heads may carry the cam to higher rpm than the specs would suggest. He expected the cam to be done by about 6000rpms, but I was hoping for more . He said we may get it, but I didn't expect a tiny 220 at .050 cam to buzz cleanly to 7000rpms. Its a combo that I lucked up on, but we did all we could to maximize what we had to work with. I couldn't be happier with the choice to give Tim a call and let him grind a baby cam for me and Id be more than glad to share the specs with anyone that wants to have their cake and eat it too, LOL.
