I'm in the UK and V8's are not necessarily rare, but it takes a true petrolhead to run one day-to-day due to the daylight robbery of the high tax we pay to enjoy such a brute.
On films and some youtube racing I've watched, some of the american V8 cars seem to have a real grizzly snarling engine noise at idle and I want this. I'm happy for the exhaust to thump in time with the cylinder stroke, but desperatley want my engine idel to frighten small children and cause pedestrian passers by to 'tut' when I'm sat at the lights.
What can I do to achieve this filthy man juice noise?

I install a Solo Performance Thunder-Res Cat Back Exhaust system.

Hey Badger, sounds like you are in need of a new cam with some big ole’ lobes on it and some free-flowing exhaust there mate. It’ll give you that American muscle car sound you’re after.

Cam time! And some aftermarket exhaust to go with it.

Are cams easy enough to change or does this motor mean it's an engine-out job?

I've had a quick look and I doubt I'd have the room to slide them out. Anyone know how long this takes and are there any performance gains on the SRT without a remap?

(My new porn since yesterday seems to be trawling through youtube watching start-up of cams/pipes now :-D Who needs a vagina when there are cams.)

Cam your going to need to spend $$$ at minimum lifters and cam and gaskets and you really need full exhaust, air intake and crank breather modifications and tune so that’s already pushing 4 to 5 grand and for that basic no springs upgrade and a good tune doing the work yourself could expect 10 to 20% rwhp gain from what I’ve researched how much you gain is dependent on the cam chosen you might get a great sound from the cam but the lift and duration want to match your airflow otherwise you might find the power gain is not in the rev range you want and the gain wasted

I've seen upto 60bhp gain with what you've listed, and endured many camshaft information videos highlighting gains and losses after installation.
My verdict: can of worms. Professional and experienced installer/tuner job.

Well I’m all for diy talk to modern muscle and instead choose the right cam allot of those you tube videos etc they have just gone and chosen a huge cam lift for sound little research and nothing to increase air flow and then say cam upgrades are a waste of money and time, you just have to match it and there are significant gains to be had without going to crazy I can’t find it now but I did post a while ago with the air flow cc after some 6.4ltr Apache stock heads were ported and the increase at all valve lift heights up to 0.6 showed 10% gains pretty significant port the intake manifold and throttle body and a big cam is going to show significant power increase but like you say the tune will be the make or break

Agreed. There seems to be alot more maths behind a cam exchange than I though. Expert advice required before I ruin the motor.

Well generally a big lift can will rob the bottom end cause down on the low part of the lift it takes for energy from the crank to open the valve with heavier springs for big lift the short of it is I think for a cam upgrade you really need first to decide what info anything your going to do to increase air flow starting from the air intake to the intake port of the head then you can zero in on the cam and where you want the power
