ThermoQuad info and kit question

Well I don't like adapters. I think an intake designed for a spreadbore should have better cylinder to cylinder distribution with a spreadbore on it, and same with a 'square bore.'
The LD340 with a t-quad on it was a bit of trick for racing in 'stock'. The back bores were opened up (carefully because the sealing surface then is greatly reduced), the divider cut down, and IIRC notches cut into the boosters to direct the fuel to the runners that would otherwise be shy.
