Blue 69 You have a tougher job that mine. You have all the skills. This doesn't show up on the the thread. Only other side note is rubber clamps on the hoses and the looping of the r/s one up and around the top of he inlet of the radiator. If not done right it will rub the crap out of the fiberglass. Looking foward to see your build.
Have you thought about motor and trans? Plenty of 427 so motors down your way from all the old boats. Block is most important the heads are all different sizes and shapes, like women.
