gday all recently blew my banshee up its got damage to the bores and the head. It was running a 409 kit i am looking at either getting another 409 kit with new cylinders and head or i am pretty keen to give the 480cc T-REX Cylinder kit a go. Has anyone had much experince with the 480 kits, if so what are they like? what parts do i need to get that arent supplied in the kits? and what are the t rex cylinders like?
