EFI help

im considering to put it onto my 408 stroker. i want to keep the look of a stock engine from the time period. my budget will be considered by my options. just want to get good MPG and good power when at the track. self tuning is a must
I run the Holley Sniper on my 408 and its been great. I had a few issues with an external fuel pump in the beginning but the system itself has been great. Plug and play, very basic set up and you're up and running in not time.
