    If I had to take one it would be the top one for the roller cam.

    But honestly, I'd spend more and buy a used LSx , than bother messing with a conventional sb.

    They both look good -- I can understand your dilemma. The torque of the 383 would probably sway me to that engine over the 350 with the GM 'HOT' cam. Having ran a 413ci small block with ported Vortecs and a hyd FT cam with very similar specs -- 234/244 .488"/.510" 114° LSA -- I'd have to say that engine will really rip. I'd go for the 383 if it was me.

    If I had to pick I'd go with #2 I love my 383. Have you considered getting a short block and then you can hand pick everything else like your cam, heads, intake, etc?

    Tough call, I love the roller cam. But I love the torque of the 383. The first engine has ported heads so a bigger cam might wake it up. I'd like to see what the 1st engine would do with the 2nd engines cam specs. I wonder why the 2nd engine isn't producing more HP with those cubes and that cam. Where does your stall converter stall at?. That 2nd cam is substantially bigger than what a stock converter can handle, I would think. So do you have to spend a few hundred more for another converter? Also it doesn't come with a balancer and flexplate so add that in the difference. A stall, balancer, and flexplate can add another $500 or so.


    Lowend, yea, thats cheap!

    #2 costs about half of what it should, I'm telling you; it's not a good buy.
    A good 383 should cost $4.5-$6K done right
