So, looking at older gearbox options, a nice plain old mechanical system would be good, or limited electronics, such as a gearbox and TCU that don't need to talk to anything else to work. just power from the flywheel, through the torque converter, and outputted on to the drive shaft.
Also trying to lay my hands on a set of exhaust manifolds as the block didn't come with any, I've seen some Kleeman ones on Ebay, but they're a bit pricey to say the least! and as long as i can fit the wideband O2's into the standard ones, i don't think i need anything special at this moment!
So boys, Gearbox advice down the route of whats already been suggested, anyone got a good idea of what might work? I reckon i can fabricate a bit of a bell housing adaptor if needed!
