170 Slant six fuel injection - HELP

I run a MegaSquirt MS3 pro on the slant in the 68 Barracuda.
Use a throttle body off a GM Vortec, all GM sensors. I made an adapter that mounted the TB to a Clifford intake, I”ll get photos later today. There is a posting at slant six.org that lists a company making fuel rails and a bolt on ready intake for FI.
If you have an A body, check Tanks Inc, they have really nice fuel tanks, pumps for our FI cars.
By the way I will never use 1/2 the capability of the MS3 Pro, check MegaSquirt, they have other options that also work fine.
