Thats some pretty cool stuff there, cant wait to see it finished.
My plans are to start with a 3.3 probably an 81 as they seem to be the most common with the inline six. I want to minimise the amount of fabrication and mods, so i can focus on spending on the drivetrain and suspension.
Probably wont work out like planned (it never does), but from my research the aussie block shares most of the same mounting points for the mounts and accessories, if i go an auto, a C4 should bolt up in place of the factory C3, the starter will be on the opposite side to the factory one but shouldn't be a challange. A cortina sump will solve the K frame issue (could just pull the entire crossy from my TE). Will need to fabricate some throttle linkages but i havent decided about carbs yet so that will go hand in hand.
I reckon that i will come across plenty of other issues along the way but gotta clear the first hurdle, getting the car in the first place.
