Removing DOD hardware & fitting a larger camshaft

[jbradsh1]

Thanks. Can you interpret the numbers for me? I am thinking about doing a cam upgrade along with loosing the DOD but I don't want to change my current mods (Kooks shorties, R-F, hsrk). So I'm thinking a mild to medium street cam. What do ya think?

[Andy@Livernois]

the only issue's with the hot cams is they are rather lopey for their size because of the tight LSA, usually L76/L92/LS3 stuff like 114-115 LSA's from what we have seen in our tests

Lope is good as long as its not really heavy.

If it makes 480hp/475tq with manifolds, non ported intake/TB, 10.9 compression, what will a HOT cam do in a car like mine? To me its a no brainer. 540 at the crank should be very easy with 11.1, cleaned up heads w/better valves, ported intake and TB as well as the 1 7/8 headers. Tell me I am wrong.

How much torque till the tranny calls it quit's?

I want to keep mine right at 500ish. The Vettes are doing it, but the strain on ours is launching a 4000lb car.

I am assuming that is flywheel power? I don't know. Maybe I have a abd taste in my mouth against hot cams. The LS6 hot cam I had in my camaro sucked bad. Luckily I didn't invest into that cam, but driveability was bad considering the size, and it made less horse by a long shot then our stage 1 cam does.

Don't get me wrong I am interested in seeing what a hot cam will do. But in my experiences the hotcams have always had bad driveability compared to more aggressive profiles, and are soft on power. We also lose a good bit of flow having a .070 smaller bore then an LS3.

So Andy, what would you recommend for my set-up (see post just above yours)? I want to get a few opinions so I can make a good decision. Thanks in advance.

I would say our stage 1 cam it's 224/230 .581/.590 on a 114 LSA. This is the cam we designed when using L92 heads on an LS2 shortblock with an L76 intake. Esentially the L76 motor in the G8 is all of these things, it has a slightly smaller bore then an LS2.

This is why HSV put these exact specs in this thread. It is a cam very suited for this setup w/ very good performance gains.

Thanks very much. Can I assume this is a non-DOD cam, i.e., you remove the DOD valvetrain?
