How can I improve this Cobra?

[ERA427]

Perhaps a strange question for this forum but…

I have a 1995 ERA 427 S/C. It a beautiful dark metallic green with white stripes. It has stainless pipes (powder coated black for authenticity), Trigo pin drive wheels and it’s visually is the prettiest one I’ve seen. Nothing is broken. It always starts, never stalls, sounds great at every RPM, has great throttle response, and sounds better than it looks. Interior is perfect – like all ERAs.

Underneath, it has front and rear anti sway bars, Jag rear end w/3.45:1 rear gear. It has a Tremec TKO 5-speed. It’s being powered by a 1966 428 FE, with the 1966 PI aluminum intake, and 1968 CJ heads, and Holly 750 4bbl. Mallory ignition. Canton oil pan and remote oil cooler. It’s got the right LeMans valve covers and air cleaner.

Sure, I wish it had a side oiler with dual quads but that’s not gonna happen.

I don’t use it on the track. I’ve had it for one year. Yes, I know it’s not “real”, but it’s an extremely “stock” build (plus the CJ heads – but they are visually identical from the outside). I like that it is quite authentic and I wouldn’t want to do anything that would make it more obviously fake.

So again, it runs perfect but I can’t help but to continue to think of ways to make it better from a performance standpoint. I don’t know why I want to, but… you know the deal… What should I do that makes any sense?

I expect that many would say “don’t mess with it.”

Seems like new heads, intake and or cam would be logical upgrades. But seems like a shame to lose the 1966 PI aluminum intake and the 1968 CJ heads. That leaves the cam. As far as I know, it was a fairly stock rebuild on the engine, when it was recommissioned in 1995.

What would the effect of a more aggressive cam be?
Would I be asking for trouble by going down this path?
Easy or hard to do?

Again – currently it all works and drives perfect so I know this is nuts, but here I am…
