I really need some advice here

That's the way I see it too. I feel like extra money on a crank would be a waist for my purpose. Heads probably not so much. I certainly don't want to be constantly breaking traction which is why I was asking about a build that would launch hard while going down the road already. Which, again, is why I mentioned a de-stroked motor on nitrous. Seemed like there wouldn't be a traction problem at say 3000rpm and up and it would get to the peak power rpm range quick.

But I trust you guys and I'm hearing keep it simple and the power from a bored out 360 with worked 308's or even after market heads with a great valve train will do the trick just fine,

Suspension on car is great. Lowered, front and rear sway bars, heavy duty rear springs and good shocks, disk brakes on front. Has no body roll that I can tell. Feels like a go cart. A whole lot better than the Charger patrol car I once had, at least in cornering.

Never tried to launch it hard cause I just didn't care to break something. It has no subframe connectors.

So I take it 425-450 HP is about what I would need before I have to start tweaking the suspension and tires. I'm guessing the Barracuda weighs about 3300lbs.

Thanks again.

BTW if those 308 heads have a crack between the intake and exhaust valves and I could get my hands on some W2's with shaft mounted roller rockers that have been milled and ported with 2.02's in them would they work on the later model LA. Seems like they do have the bores in the block for LA type oiling but wouldn't I need a different push rod length.
