The engine comes equipped with a hydraulic roller camshaft. Why would you want to change to a flat lifters cam which usually results in less performance and reliability?

Wait, you're wanting to buy a turn key roller cam crate engine and put in a flat tappet cam? You don't want to do that. For starters (without getting into all the differences), the roller lifters in the engine won't work with a flat tappet cam, and neither will the timing chain set.

Summit said that was the wrong cam. I still hate calling them.
I dont want to buy that engine. I have that engine minus the heads. I pulled my engine code and it comes back to that ZZ4 motor. But some where along the line the aluminum heads went away. Cause mine are cast.
That was why I was asking you Camaro 69.
Im not sure I understand what I really have. That cam said hydraulic, and I thought that was what mattered. Can you point me in the direction of a roller verses flat lesson? Does that mean I have to spend like $800 for a cam. That really sucks. The cam in this thing is week. I wish I new if it still had roller lifters or not.
Will you (Camaro 69) point me towards a cam. This is a race car. Will get 2.02 Aluminum heads.

Here's some information to explain the cam differences: http://www.chevyhiperformance.com/te...nfo/index.html
I need to dig through my archives. I had a link to also explain the differences between a roller and flat tappet cam block.
The major difference of concern is where and how the snout of the cam sticks out of the block. And the roller block has a thrust plate for the cam where the flat doesn't.

With a worn cam/flat tappet lifter set, you do need to change lifters with the cam. If you don't, you're just asking for future trouble. Roller lifters don't create a unique wear pattern to the cam lobes like flats do, so you can reuse rollers providing they aren't shot.
Compare if you were to change the engine over to a flat tappet cam. In addition to the cam (a wash), you need:
new lifters, new push rods (roller rods are shorter), new timing chain set for a non roller (you could reuse yours with the roller cam if it doesn't have a lot of miles/wear), change the distributor gear (different hardness). So, even if you needed new roller lifters, it would be worth it to keep the engine a roller.

Thanks Camaro 69, you are a big help.
So, I can get a new Cam, I will get a double roller chain, just cause I always change those when I have it apart. And if everything is in good shape then that is all I need.
I am thinking this cam: http://www.summitracing.com/parts/NAL-19244485/
Lift small enough that it should work with my current heads.
I was told I wanted 110 separation, will a 112 separation make it lope more?
Will it still idle at least a little?
The power range is where I want to be. I have a small stall and have been able to launch at 2000 rpm, and I set everything else up to shift in the 6200 range. I am willing to add a 2500 stall, but would rather find a cam that has a power range like this one.
Thanks Again
