Default Later carburated engine ?

Is it worth it to buy a later engine block with the the hydraulic roller capability and still make it carburated?

Am I better off ?

Definitely. It's a lot easier and cheaper (assuming you're rebuilding) than converting a flat-tappet block to roller, and there are a lot more cams available

Ooooo!!! One more question , Will having a more aggresive cam capability like what was just said above Help more in Torque ... or more along the lines of Hp ?

Thanks

Both. I'm running a 91 roller block with a carburetor. A good roller cam will let you make good torque and hp. You want the best average power in a street car, not the best up top or the best down low only.

Yeah, it helps both. The advantage of a roller cam is being able to have a much steeper ramp on the cam lobes, meaning the valves can open faster without worrying about chopping a lifter. This means that you can increase duration @ .050" without resulting in heaps of valve overlap like you'd have with a flat-tappet cam. Valve overlap causes poor idle and low-rpm throttle response. So with a roller cam you can increase lift and durationfor better high-rpm power while still retaining low-end torque and driveability.

And they don't wear out like flat tappets do. Plus for a cam of the same rpm range you make more power everywhere with a roller

roller cam is nice in any engine its alot smoother.ever seen a old flat tappet cam with a lobe wore down.
