I tried it - twice. The first time was circa 1997 with a L28 at 9.83:1 CR and a street cam. The engine was fresh and the car ran like crap. It had low power, wouldn't idle and was simply a disaster. Since the engine was new and the EFI a bit untested, I removed the cam and related components and returned the engine to a stock cam. It ran great and I was able to enjoy the car. The performance cam sat on a shelf for a decade or so. My Z was running great and was well-sorted, so I figured that I would try again. I installed the same cam and related parts back into the engine and got the same result. I tried to tune it, but it didn't make enough vacuum to keep the L-Jet happy. I once again pulled the cam springs and rockers and went back to stock.
I then installed that cam into my SU carbed L28 racecar and it runs like a dream. It was everything I had hoped for in my street car. Both engines are very similar other than the fuel systems.
You can try it, but many have the same results as me. L-Jet simply doesn't like low vacuum.
For reference, my cam is a Web Racing Grind 91 with .450 lift and 260 duration
