RE: {Chrysler 300} We don't have

What James wrote is true, two sets of 30" Ram tubes dimensioned the same, the shorter ones are shorter internally. Short rams are smooth on top. The only Rams shorter were the Max Wedge induction used on the 62 Dodge & Plymouth and on the 64 Hemi.

Many of you know this but it was Jim Thornton and Tom Hoover, Chrysler engineers who founded the Ramchargers racing team. These guys had an obsession with "pipes" both intake and exhaust as evidenced by their first race car:

The Ramchargers experimented with pipes until they found the optimum combination. Meanwhile at their day jobs Ram Induction was perfected. When Lynn Townsend's teenage sons complained that Chrysler products were not "cool" like that of Chevy & Pontiac Lynn gave Hoover orders and a pad of pre-signed change orders to put Chrysler first on nearly every track, and he did. Previous Company president Newberg aided and abetted this effort by downsizing Dodge & Plymouth sedans for 62, notwithstanding his decision was not about racing but rumor Chevy was downsizing its big cars.

I may be wrong, but I thought that the difference in the "long rams" versus the "short rams" was the length of the internal divider. The actual overall length was the same.

I remember reading about the work during WWII on the sonic nature of intakes and how it was applied to make the ram manifolds. I assumed that the length of the internal divider changes the RPM range of the sonic "boost".

It has been decades since I read up on that so it could all be a mess in my head!

As far as I can tell,

we don't have much on the 405 horse ram option H.

I came across something that says the H short rams

are shorter than the J short rams. Really?

Short short rams, I've never heard of that.

Other questions come to mind:

Did it have a special cam?

What did they do for exhaust manifolds?

How did they get the 11/1 compression ratio?

If this was a dealer installed option, just how much did

they have to change -- seems like an unreasonably big job.

If you have information, please send it to me so I can

assemble an article.

Bob
