Can't wait to see some dyno action from this baby!

Dyno numbers have been out for years.About 30 HP over a dual plane 800 CFM single 500plus HP engine.Tom

Got ya. That's impressive gain. Does this have some design improvements though?

[tom s]

Has a V plenum,when I tested the diff designs before there was only about 5 HP diff between all 3 on a 462 HiPo street Eheaded engine.Im sure with a high RPM race engine and ported to match it will be better.Tom

Great progress Tom. When I get my intake, (I didn't say if), I will dyno my combination for sure. Very optimistic about how this is moving along.

Looking really Nice Tom.

Sorry if i missed this info, but how long are the runners, port runners height and width at plenum? Will ports at flange be stock or ra4 sized?

[tom s]

Ports have been reduced down to stock size ports with room to make bigger.When I get the intake back I will give you the numbers on the runners.Tom

Thanks Tom! Things are looking really good right now, keep up the great work!

On top of the evident bling factor, how would this race type manifold with dual carbs affect the performance of a 'healthy' 400? I would suspect the over carburetion would detract from the performance. What was the original application for them?

421s,with progressive linkage your driving on a 2bbl.Tom

It appears he certainly did, thank him for us please, this is beautiful, absolute art, much thanks Tom!

You can see the original location for a 2bbl in the center of the 4 bbls, more on that subject in recent Smoke Signals articles.

Looks great Tom!
Nice work.

[mgarblik]

What a cool conversation piece! Hope it fits as expected. Great progress. Keep the momentum going. This baby is up to a crawl now!!

First off awesome job Tom getting this done!!
Sorry to ask, without scrolling back through all the post, does this 3d intake fit early or late heads? The water crossover looks odd to me for the later heads??

[tom s]

The plastic is early but looks the same from the top,will post pics of it and the converted one side by side tonight.Tom

I feel like this whole process is like watching a baby bird egg hatch into an Eagle...and she will soon fly when ready.

Amazing process, progression, precision and ultimately desirable (factory style) performance is on the horizon. Well done Tom and team.

I was told by the guy that helped on this project who has done many of this type of project and he equated it to exactly like waiting for the birth of a child.Not quite.Tom
