yep, seen the csc crossover within the big old crossover versus straight, and equal versus unequal debate threads some time ago.
still not sure who won!
there is valid argument for both types, crossover with unequal length probably ticks the most boxes when it come to gas speed and flow dynamics, straight with unequal a very close second, probably down a tiny bit on scavenge, but only if the crossover version is perfect, i think a well thought out straight unequal length would work every bit as well, pretty much!
however, the customer gets what they want, and if you wanted it like the csc, we would endeavour to give you just that, just not as a replica or exact copy of someone elses work, thats just not cricket!
As a custom build, it would never quite be that anyway, so no worries for us there, plus, is the csc still produced anywhere?
Anyhoo, yes very do-able, but we would have to ramp the car to quote precisely, but i can get a rough idea from any decent images you may have?
