new rules for '68 Hemis
 

I heard that one reason the '68 SS/AH cars have gotten quicker is some recent new rules for those cars.

Can anyone filll me in on what those new rules might be, and how they're being implemented to enhance those cars' performance?


Additionally, the '67 RO 23 cars seem to be a bastard engine; competition hemi reciprocating assy. and heads with a street hemi-style intake.

Is that true, and how does that intake affect the HP factor (compared with the short cross ram on the earlier cars???)

That emgine may have been on the '66 motors, too.... Can't remember.

Please excuse my ignorance...

clutchless trans and a million rpm.

Just put an original 68 car next to a 2010 car and look.And that's just the beginning.

Re: new rules for '68 Hemis
 

Ed, I'm sure the intake manifolds have changed dramatically, but I am ignorant of what kind of changes these cars enjoy that are not allowed on other "pure" Super Stock cars, if any.

Just curious.... and thanks for any specific information.

Quickly,tube front suspension pieces,rack and pinion,rear wheel wells big enough to house a family of illegal aliens.Under the hood is like a Model A compared to a new
CJ engine.

Re: new rules for '68 Hemis
 

Rack and pinion's? Tubular front end pieces? Are you still refering to the 68cuda only? Or Superstock Mod etc?

Re: new rules for '68 Hemis
 

There are NO tube front end or rack and pinions on the 68 cars. Stock control arms and steering boxes on the 68's. Dyno

Maybe pro stock cam shafts and Honda bearings, all we need is titanium valves to save some $$$ in the long run.

Re: new rules for '68 Hemis
 

Lots of CASH!!

Re: new rules for '68 Hemis
 

Thanks.... I think.....

Re: new rules for '68 Hemis
 

I like some of the smart aleck comments posted, lol. Seriously though there has been many changes over the years to squeeze out a couple more tenths out the engines, with high tech engine components, transmissions, or on the cars suspension. Some of the $$$ money these guys spend on their cars today is unreal, as compared to what an original were built to do.

Re: new rules for '68 Hemis
 

Bill, the most important rule change was intake modifications (inline as opposed to traditional cross ram) that prompted higher rpms which led to very stiff valve springs which led to etc.

Re: new rules for '68 Hemis
 

It's not all engine mods that are just for Hemis.
Look real close at some of the creative body modifications.

Re: new rules for '68 Hemis
 

Next time you're in the pits someone should snap some pictures of these trick parts that they are using on today's Super Stocker's and lets see how well that goes over, lol.

Re: new rules for '68 Hemis
 

Adger,,,,creative body modifications?? I guess its been a while since I've studied a 68' Cuda or Dart body,,,or else my eyes are getting bad. Care to elaborate on what we're looking for? You don't have to mention any names,,,just say "some Cudas are doing this, (insert creativity) and some Darts are doing this." (insert other creativity) I'm deffinately going to look a little closer at the next national or divisional event I go to.
Thanks for your info,,,take care.

That is what you need to do, Danny

Bodies are Channeled????? In other word's floor pans are higher than orginal?

Re: new rules for '68 Hemis
 

Check out the firewall locations for starters. Can you say engine set back ! Major and I mean MAJOR cylinder head mods plus billet CNC'd intake manifolds 55 mm roller bearing camshafts. relocated exhaust rocker shafts. approx .400 thou cut off the block deck for less wt. in the piston. Lots of RPM and less engine life. Lots of $$$$$$

Re: new rules for '68 Hemis
 

Thanks Ralph and Terry for the input,,,,,,,I'll be looking.

Re: new rules for '68 Hemis
 

One of the tricks was just like we did in stock, figure out a way to run more RPM and still make power. For stock it was valve springs and Shubecks, for super stock it is valve springs, light bottom end (within the rules), re-aligning the push rods, tons of mods on the heads and basically in-line carbs on the intake. I would agree that some may have pushed the limits on the body and chassis but the car still has to weigh a minumum of 3210 ... still impressive to run 8.20's at 160 with a 42 year old car ..

I love to watch the Hemi shootouts, but it has turned into a mega dollar class. You almost have to have your own dyno and engine development to catch up or get ahead. Same thing that happened to top stock, cost way too much and only a few could afford to compete ..
