Best intake for a 565
R/M Dart 355 cnc heads
R/M 420-116 cam
14.5 on compression
1150 alcohol carb
2750lb. door car
current intake is a dart.
Ported Edelbrock 2927 with a 1-inch spacer is what Scott Foxwell setup for mine.

565 and Sniper Jr here with same cam, CNC 345 heads but with alky injection and very happy with the performance, solid mid 4.70 car. I switched from a Dart to the Sniper jr 5 years ago and picked up some. Just remember a Sniper is not a bolt on manifold, it requires some port matching
I am leaning towards the SV-565 also. Heavy car but on alky so this should work well. The first version of the SV would also work well but the SV-565 should be better

I would also look at the victor junior as well. Just remember with any of them you will be doing some port matching to your heads. I would call to find out how much. The one thing about the sniper's is they do not fit well and do not line up well on most heads. I had a set on mine and they didn't line up very well. Combo still ran well but it will have a port d Brodie on it this year.

The SV 565 needs to be on a Cylinder head that flows at least 440CFMs.Bill C.

I've been stating that for years here, told to me by the guy who developed the manifold from which it was copied.
But the majority of bracket racers are clueless and believe the marketing and Internet talk from the misinformed, naive and clueless like themselves.
Fact is many bracket racers are using heads, manifolds, headers and carbs that are too big for optimum performance for the rpm they chose to turn, the trans/gear/tire behind the engine and the car weight they are launching.
With the right parts, they would run tenths quicker.This message has been edited. Last edited by: 1320racer,
Couldn't have said it better myself.
Not to be a wise ars, but that statement is ridiculous.
The entire combination needs to be considered when selecting any/all parts. One motor combo could work great in a light car but not so great in a heavy one. Fuel also has to be considered also.
So back to the tread...
His current intake is old! and was never really designed for the 4500 carb to boot. There are a number of intakes available now that will provide a decent boost in performance. The SV-565 could be one of them along with a few others! In order to provide a better recommendation more info on the combo that what was provided is required. And to say the SV-565 needs a head that will flow 440 to work s just not true.
In general your statement about many combo's out there using stuff that is too big is true more often than not.
I deleted my post but I agree with Top 100% and have the time slips to prove it...
My heads do not on paper flow that and the more important part is I am SUPER COMP racing....
My engine pulls up from well under 5000rpm in high gear and runs more MPH with this SV-565 intake even with a plate stop under the carb....and is at 7400 at the stripe.....
The part about mismatched components and to big this or that can be true but more often it is just people that don't know S-h-I-t and can't tuna fish......LOL
I sent out my Dart intake to be ported for my combination. On a side note, I used an out of the box merlin intake on a 540 that I thought was a junk manifold, and the car flies. Shows you what I know lol.
I didn't just fall off a Turnip truck and I can tell you the progression of intake manifold designs has followed the heads they sit on.
Darts were a huge intake when stock heads were what most people used and a 509 was a really big engine.
That intake made more power on Super Stock 427 and 454 engines with iron heads and by a quite a bit compared to most everything else.
Just one look at an SV-565 from the outside and you can see how much better it is....port layout up to carb flange....
If you can't see it you need glasses.....
The Merlin intake is actually a very good intake..Even better with a bit of work.

I have a sv565 intake if anyone is interested you can email me at email@example.com. We're changing to tall deck/spreadport heads so we're going to sell it.
Interesting read here on the subject of intakes good and bad.
In looking at the major engine builders web offerings the majority look to be using the Eddy 2927 on the 540-565CI engines.
Seems pretty hard to beat that as a standard.
With that being said the Profiler sniper and sniper Jr. looks like a pretty good piece as well.
Problem is that the Profiler intake is quite a bit more money than the Eddy intake.
Has anybody had first hand or A B A test results between the two intakes?
Experience is what you get when you don't get what you want.
