Vintage Engine Showdown! Which Setup Has More Power? | Engine Masters | MotorTrend

It's another battle of old-school cool here on Engine Masters, where the guys bolt tunnel-ram and cross-ram setups to the 383 Chevy and stagger jets until their gasoline-soaked hearts are content.

Just like I told Richard Holdener several weeks ago during a live show, the cross ram is the best tunnel ram that fits under your stock hood. Chevy designed it because the SCCA Trans Am series rules said the carbs had to fit under the stock hood.

I would sacrifice that little bit of power and choose the cross ram over the tunnel.
No hood hacking 👍👍

If you want to modify the tunnel ram or the cross ram it's easier to balance out the ports and and modify the 5 and 7 ports to help out from Robing each other. Also you can put dams in the bottom of the crossram to help with fuel distribution. They did it with the Smokey rams.

ive only wanted to see a test like this for like 16 years now. love it!

I like the tunnel ram WAY better, it looks great on my truck, a 72 Chevy Cheyenne super, its a great little truck!!!

[transmissionman]

I love ALL the engine master stuff, great job.

Which begs the question, What would the cross-ram do with 1" or 2" carb spacers on it?

[rickhaile]

Very informative! Too bad Dyno sessions are so expensive. And so few people have the experience and knowledge to run them! Keep making videos along these lines please!

[MrTaylorTexas]

Great info. I'm about to put bigger heads and a weiand tunnel ram on my Chevy II, so this stuff is great to watch. It's surprising how well the cross ram performed when all the magazines I've ever read have said how soggy these manifolds are and one should stay away from them.

Everything traces its roots back to Chrysler, EFI, hemi-chambers, tuned runners, the downdraft carb, A/C (that actually works), disk brakes (1949), automatic overdrive, key start, cruise control, sliced bread, the civil rights movement, and those little finger cuff things, those are cool.

Love the looks and performance of that cross ram, great test.

I have run a two 4 bbl Cross ram and a 3X 2bbl factory intake on my 71 Dodge Demon 340.
The 3x2bbl actually performed the best.

[edwardpate]

Hard to beat a good single plane 4 barrel setup all around.

Just saw Luckys video David. The Disgustang is looking good. Quite the opposite of what it started looking like !👍💪

[FSHSKainon]

Love you guys !! Love these vids !!, thank you !!

I have to say so far on my MotorTrend delve, Engine Masters has been my favorite episodes. You have the nerdy op for techies, power bangers for speed freaks, the close circle of coworkers/buddies meshing together on an objective topic, and the histroical nature to preserve information and numerical data. While I do enjoy Frieburger and Finnegan a bunch with the garbage builds, this show does give a scientific gravitas to further help the layman try to work on his rig on his own property.

The very first tunnel ram I saw was home made from an early Rochester mechanical fuel injection manifold from a Corvette. It did pretty well. But today, it's considered heresy! LOL

[AndyFromBeaverton]

I love the radiator hose setup. Put 4 Webers on and use steel belted radiator hoses and it would be a sweet-looking setup.

[AMCguy]

Crossram all the way! The sound is so cool. Plus if used like how the AMX scramblers first pioneered, with a forced induction hood. They can match a tunnel ram

[CarsandCats]

Modifying a Weiand tunnel ram for a BBM right now! The top was WAY off from matching the bottom and had to do a lot of port work. It's on my YouTube channel.
