I have noticed a few posts on EFI so I thought I would convey my experience. Actually this is my first EFI system, but the results have been notable. I had the system installed by the man who built my engine. He has installed several EFI systems (FAST,FiTECH, and Holley), in his opinion he likes the Holley Sniper the best, so that is what I went with. Here are the specifics on the car and motor:
1) 1964 Dodge Polara 500
2) 3.54 gears, P295/55 -15 ET Street SS tires
3) 500 cubic inch stroker (400 block)
4) ProComp CNC ported Aluminum heads 325 CC intake runners
5) Heads flow 330 cfm intake, 250 cfm exhaust @ 28"
6) Harlan Sharpe, roller tip, 1.5 ratio rockers
7) 230/236 @ .050", .550" lift Comp Roller Cam
8) Torker Intake
9) TTI Headers, 1 3/4" Primary, 3" collectors
10) 1800 RPM stall, the motor is a torque monster.
11) 9-1 Compression
On the original build I had a 800 CFM AVS Thunder Series Carb. Now that we have installed the Holley Sniper EFI the car is a completely different beast. It is set up to run a F/A ratio of 12.5 @ W.O.T, 13.5 at cruising, and 14 at idle. The car starts almost instantly and the throttle response is immediate. No hesitation and no bogging. I would highly recommend the switch
