I KNOW the 302 tuning game is more varied than you give it credit for

And the figures on that graph go from 200bhp to 1100bhp and 250lbft to 1100lbft, much wider than it will on YBs at both ends.

Those cars go from NON turbo stock engines, to twin T25 on a stock engine, to race fuelled thumper turbo'd monsters. There is no set way of tuning them like YBs, I doubt there more than 2 cars with the same sorta turbo or turbos on that whole graph.

They go from stock iron heads to iron gt40s to loads of different brands of aftermarket heads, each countless valve, port, runner and chamber sizes, many even with ports and plugs in different places, again, doubt there more than 2 cars with the same type head.

Same goes for cams, the variation they use is riduclous, and same for compression, id bet it varies from 7s to 11s.

Inlet and exhaust manifolds too, I doubt more than 2 cars run the same.
The exhaust manifolds are stock ones adapted, log ones, tubular ones, all kinds of lengths and bores.
Inlets are similar, ridiculous amounts of styles and sizes used, not to mention some carb and some injection.

And you think there is more variety here? I certainly dont, not by a long shot.

BUT despite all that, there is a bizzarely close corrolation between it all, especially in torque, so it would be interesting to see if its the same on YBs, as no reason it shouldnt be with all engines, making it an interesting thing to do if someone can be bothered, no matter how much you are trying to pit it down.

Like the drugs thread, its probably best you understand the other side of the argument first.
