Not all old school cars were that easy.
When I put headers on my Boss 302, I had to disconnect the motor mount and jack up the engine to get them on because of the steering set-up.
I did this in a old garage with fifty year old screw jacks .
Had just enough room to slide under the car.
The worst part were bolts you could not see , in a tight area, so it was by feel and by guess and by gosh.
I did it in one day but I had bloody hands.
The long tubes are much better all around than shorties.
I was in a antique/women's junk shop yesterday and saw an old Sun engine tuner, I mean old this one was probably from the fifties for 300 dollars.
Assuming it still fully worked if you ever need to check your compression, fuel pump pressure along with other items pre-computer cars had it would be handy plus it had cabinet space for spare parts, but that is priced way, way, way to0 high and unless you have all the cables and manual, best to leave for some one who simply wants it as a decoration.
The last most complete one's were the first to use digital tech. and with my 1978 Olds would be nice to have.
Now a Sun Distributor tester is always good to have as you can check and set a distributor quickly but Sun is long gone, while King was still around 9 years ago but now is gone again.
Jay Leno uses a King on his cars.
