Trouble getting a slant six in the car

I always like the " run the hot wires in and out the bulkhead thru holes. It eliminates so many times where you are not getting fire inside. Maybe not the right way, but it works!!! NO NOT trying to sound like those dudes on RoadKill!!! BUT....
I am 74 and still have a lot to learn. It doesn't help that I have forget half what I did know either!
But, learning is so much fun and the sense of accomplishment is rewarding. For me, even the smallest victory! Who can afford to pay someone to build your hobby car!????
Hint: Bodywork. Remember IF at first it does make YOU happy you an go right back and keep on till it suits YOU!!!
