1/4 mile ET guesses
I like MSD stuff, it's just pretty expensive when buying new. The distributor is a yes.
You could do a cheaper conversion using some factory pieces. Grab a stock box/harness and wire it in using an MSD distributor. Got any junkyards close? That's where I'd look. You can also get a module from rockauto cheap ~$12.
High headwind probably killed some MPH on you.
Good luck with it.
