EFI considerations for a 1970 383 with very mid cam

Last year I installed the Gen 1 Sniper and am now driving it more and I love it. Easy start, faster warm up, will high idle without fuss, Cruises easy and goes like hell. I did the entire system, Hyperspark distributor, ignition box, fuel pump (you don't need a return with their pump), etc. The Gen 2 stuff looks even easier. I will say there is a lot of support for the Sniper as is their other EFI systems. I'm not a Holley fan boy but a friend of mine has installed over 8 of these over the last 6 years with perfect results.

Regardless of what you pick be sure you have good new grounds from the block to the frame, frame to battery, and battery to frame. Also, a higher amp alternator and all the supporting mods to not burn up your harness.

It is nice to have the car sit for a few weeks and go out and turn the key and have it fire in 5 seconds (most of that being the time to prime) and back it right out of the garage and drive down the road cold.
