LT1 camshaft suggestions?

[Lynn]

JMHO, but if you want a lumpy idle, you don't want an LT-1 camshaft. Just know this; without variable valve timing or computer controlled opening, there is no "best of both worlds" once you go to the lumpy idle. You may have issues with vac for power brakes. The engine is finnicky, and more difficult to tune. But, it that is what you have your heart set on, your car, your money.

Personally, I would go with a roller. Anything radical will require pretty stiff springs. With a flat tappet cam, you will need to break it in with just the outer springs, then pull the springs and install the inners as well. Not that big of a deal if you have an engine test run stand, but a PIA to do it with the engine in the car; especially if you are working on a freshly painted car. Pucker factor increases significantly. Even then, and even with EDM lifters, you STILL run a chance of wiping a cam lobe, especially if it sits for long periods of time.
