Hello from a new member.
I hope someone can shed some light towards my recently purchased 69 coupe. It seems the previous owner has placed a 454 in that was running when picked up. Trailered home and started about three times.

With the different engine the owner had installed perhaps a HEI (me not knowing much about elect), and said this was req'd because of the difference between Pontiac and Chev. In addition he has added a switch that must be on prior to turning the key...I have traced this switch that is fed from the battery and the second red wire goes to the (distributer) or MSD or HEI.. whichever the big red distributor looking item is.
The car currently will not even turn over. I thought perhaps it seized and I removed the fan and was able to rotate the crank about a half of turn... So I suspect electrical.
Would I have to look at the starter? if so how can it be tested without removal? Or is it the distributor HEI as I have heard of? He has one that is smaller and made of billet in the trunk, but I suspect he changed this out for the reasons mentioned above.

Any accurate direction would be greatly helpful.
Thanks in advance.
