Ahhh Simon, Simon --- and so it begins.
Now that you've gone for a good strong gearbox, it won't be long before the little voice starts whispering in your ear that this new box won't even raise a sweat dealing with the stocker 302. Bit of a waste really isn't it having that good box and only that mild 302 driving through it? the voice will say. Then that same little voice will start talking about stout 351s that will suit the Tremec and deserve to be in an old champ like the RMC. And then eight stack systems. And then working side pipes ..... Sorry mate but once you start down this road there ain't no turnin' back.
We're all addicted --- but we love it !!!
