For anyone interested and read this far; the brown wire running from the back of the wiper switch into the firewall has constant 12V during IGN2. Tracing the input wire, the blue wire with yellow trace coming into the wiper switch is the input power. Tying in prior to the switch causes no loss...
This is the solution I was thinking of doing. Have to get in the schematics and isolate which wire would be correct. Thinking perhaps the 3-prong pigtail under the dash or maybe the radio harness as I don't have a radio
As stated, it's the sniper 1. Ballast is already gutted and I epoxed the jumper wire so it looks stock.
I am running the MSD 6 AL with everything wired in. Been driving it for over two years with zero issues. Tired of the hard cold starts and constant start, restart, restart if I don't drive...
I am installing the Holley Sniper 1 EFI onto my 408 Stroker.
Made a bone headed mistake and failed to isolate a switched 12V source prior to removing carb and fuel lines.
Any solid facts on which wire under the hood is a 12V switched source?
Verified the thermostat opens as it should and observed coolant flow within radiator. I have a 16" puller fan, the highest 12" fan I found pulled a little over 2000 cfm. There is a dual 12" fan setup that will pull a mid-4000 cfm with shroud.
I was leaning that way and I was going to drill two small holes near the outer ring to help with air bubbles in case some get captured in the lines and radiator
Fan is on a relay, draws 12a on startup, alternator can easily handle it. Already have a 4g wire from + alternator post to + battery post. Alleviates strain on dash wiring
I currently have an aluminum shroud that fits the radiator and has a large hole in the middle foe the single fan to pull air through. Thinking of a dual, 12" fan that comes on at different Temps so it lessens the amp draw through relays. Total CFM when both on would be 4300 CFM
I have a blueprint 408 stroker (495hp), TF727 trans, champion 3 row, 26" radiator.
Currently have a single 3100cfm thermostatic fan that turns on at 180 and off at 165 degrees.
Everything has been running great the last few weeks as I am still under the 500 mile breaking on the engine.
I have...
