The short answer is yes. But at what cost, and what final results are you looking for. Fortunately for me, two of my good friends own a speed shop. Fully equipped with CNC's dyno, and all the machine shop equipment it takes to develop and build engines. 10 years ago when we set out to see how much hp we could make out of a 525 efi based engine we had no idea. We were lucky Dustin was interested enough to tune the computers for us. After many hours modifying the intakes and countless dyno pulls, we cam to the conclusion the intake runners were too long, plenum was too small and all the modifications in the world was not fixing that design. So we went with the Hogan intakes. After about 30 more pulls and having plenum stuffers made we achieved the results on our current dyno sheets. To be honest we could got the same results with the 525 Whipple kits. And a hell of alot cheaper. If you are intent on building NA engines with a 500 efi your first bottleneck is the intakes and throttle body. Just won't flow the air needed. Once you get beyond that cu in. I personally wouldn't go any bigger than 565. Then cylinder heads is going to make you your big numbers, find yourself someone who can support their claims. It definitely is not cheap, but their comes some satisfaction from running away from those 700 stage lll boats.

I was at 640hp/670tq w AFR 315 heads, 741 cam w double swap,bigger injectors,asm mono blade but i had 8:1 compression, you can prob get a little more by bumping that

Problem is with 500/525 motors regardless of heads If were still talking lightly modified factory intake (tb, port matched), runner length, size and plenum volume kills ability to carry hp, rpms. Going to a 540 will give you more tq, it will also "runout of intake sooner". Light mods/cam, good heads get most of them in that 620 range, putting a cam in that would raise peak higher normally raises rpm tq peak happens at but hp barely goes higher up since intake is the limiting factor. some different schools of thought, some successful builds around these intakes focus on making great tq, ie, this 660, 680 range with hp falling flat at 620, 630. a cam size increase that would normally raise peak another 400, 600 rpms and gain 40, 60 hp is lucky to gain 10 and torque tradeoff is much greater. Im still torn on which way to go with my own 500 style engines, a edelbrock proflow intake will take one instantly from 620 to 680/690 hp BUT with its 5.5, 6" runners give up signifigant tq. These custom intakes if sized properly with medium length runners is real answer if its in someones budget, ie, a 6' runner makes mediocre tq, a 14" runner makes great tq but dies on top, a 7 or 8" runner thats also extended into plenum another inch or 2 would be pretty cool, Smitty

Blappppp ! lololol
Just playing here...
Choose throttle size, Make runner length per app, and then Put a flame arrestor on top. LOL
Kinsler, now owned by Holley.

the first dyno pull is with RFD bb3 CNC'ed heads 1 7/8 primary headers.
Second one with RFD 24b CNC'ed heads with 2 1/8 headers.
same cam, compression intake and throttle body. The only other difference is second one is dry sump running 10 inches of vacuum.
alot can be said of increased cylinder head tech in the last few years.

To bad mr chinaman didn't make one of these partial intakes for the bbc. Would make it much easier to make a plenum for each side and run two tbodies.

I have one of these kinsler style intakes on a 572 we’re putting in a pro touring style 69 camaro. Real cool setup with Holley hp controller.

Anyone remember that guy with the orange 50 hustler with triple 600+ cu engines? He made some nice intakes out of tunnel ram base. I can’t remember his name or find pics.

I'm doing stack injection on my 572 for my gasser, im using the borla kit. their manifold has all the vacum underneath so it gets a cleaner look and less lines to run. also no remote thermostat and filler.

That is a bad ass setup $$$$$
