I just bought myself a low km, NC fairlane ghia 1991 5.0 on LPG. very cheap! So I'm the one laughing coz I got a bit of cash money for some "small" mods.

Firstly, should i upgrade to a set of 4 into 1's or a set of tri-y's??? I'm not too hot on Pacemakers as they sound too 'tinny' to me.

Secondly, would upgrading the stock intake manifold to a "BBK #5001 SSI Mustang 5.0L Intake Manifold" (B45-5001) be possible? or what about any other Mustang Cobra 5.0L

and Thirdly, what's the standard diff? ratio? single or lsd?
