Was looking at printing a lid for the Edelbrock Victor tunnel ram. Had the lid CAD half drawn up a while ago, but it's on a lower priority.

One better... Talked to my friend that has an aluminum casting (foundry). He said that if I print up some lid cores he will cast them for me.

Do they offer a lid for a tunnel ram to accept a single Holley Sniper setup? All I see if for dual quad, im really torn on what direction to go and I know parts are hard to come by lately. I know it seems like boating season is far off but May will be here quicks an I don't want to be waiting on parts to be back on the water. Here in NY the boating season it s 3-5 months max and I don't want to miss a second of it due to slacking on having parts in time.
I debated just reusing my stock MPI for now but the whole fuel rail/injector setup I am just not a fan of. If I were to go that route how would I adapt the holley HP to the sensors on the old MPI setup for instance the throttle position?

Sniper with the Hyperspark master kit just seems like a simple setup that will work.

Yes, several tunnel rams have a 1 x 4bbl top available, but fuel distribution is horrible. Air and fuel have to take a few hard 90’s. No good reason to run a tunnel ram this way.

So in your opinion for a 509 making lets say 550-600Hp and get good bottom end what type intake would you run? I'm going to reach out to comp and see what cam they suggest as well, I'm not looking to break records just want a fun lake boat with good bottom/mid range power. also would I want a single or dual plane intake? I heard if you use a dual plane with Sniper it must be notched or a spacer has to be run, I was planning on using a spacer as well.

Front feeders suffer a bit compared to dual 4s for the same reason.

This edelbrock victor ram has bungs and fuel rail kit, which cuts down on the work. There have been questions on edelbrocks availability in general though due to buyouts and supplier switching.

The profiler is the out of the box hp king though.

Yeh, but as a note, JoeyBoost was talking about installing a tbody that had injectors. Wet flow very different from dry flow.

Get a single quad plate, mount a throttle body to it with rails and Holley HP and call it a day. Where in the power band does that intake like to shine though? Is it an off the hit to say 6,500 or does it not come alive until 3,500 rpms?

Usually better everywhere on a Dyno pull. That profiler has pretty long runners, drag guys actually have shortened them.
