Has anyone successfully installed Holley’s sniper bbd system on their slant? I know it’s listed for the Jeep six motors but was thinking it could work on a slant. Anyone?

I haven't, but have seen a few pictures of it done. The main "gotcha" (other than that it isn't as capable as port injection) is that it has the worst vulnerability to EMI that I've ever seen on fuel injection, and I spent years working as customer support for MS1 V2.2 boards. Noting insurmountable, but you want to take it into account when installing. Luckily slant sixes have their ignition pretty far away from the fuel system, but keep the plug wires far away from everything and use good quality spiral-core plug wires.

Mark Charapich has the 2bbl system on an offy or clifford intake (adapter plate) on his medium-hopped 170 in his 61 Valiant. He really likes it and drives it frequently. I can ask him more about it. He does not get on the site really, but comes to Slant 6 races and events sometimes.

Appreciate the responses guys. I’d like to try this, but am very concerned about any issues and difficulty of installation. Please keep info coming. Thanks,Steve.

Just got off the phone with a rep from Holley. He stated that one thing (but not necessarily the only thing) that would lead one to think the Holley sniper bbd would not work on a slant six is the throttle linkage hook up. I mentioned to him that my slant motor will be going into a Dodge A100 pickup, so a new throttle cable and mount would need to be done anyways. He made it sound as if this would be a somewhat easy install. At least as easy as it would be on an AMC straight six! He has certainly piqued my interest! Now my biggest hurdle is the cost!!

Got your PM. On vacation... Ping me back in 3-5 days if I have not gotten back to you.

Getting creative with the throttle linkage on a slant six EFI installation is pretty much a given.

I’ve been having to get creative with just about everything on this A100 of mine. Removed I-beam axle up front and installed IFS, added electric power steering, removed leaf spring suspension and added parallel 4link out back, and the list goes on and on. For now the EFI idea is just a wish, not sure if I’ll really do it, but you never know. There have been a few frustrating moments, but for the most part I’ve just enjoyed the challenge. Would I do it again? Probably not!
