Wasn't that article about a W2 headed 340 with a tunnel ram? I know it ran on pump gas, but I wouldn't call it streetable. My Magnum 318 is not very trick. The cam and compression are pretty conservative. It will have a slightly rouch idle, but nothing outrageous. I expect around 300 hp. If this engine isn't enough I've got another 318 block (LA not Magnum), some forged pistons, a 3.45 stroke crank to push the pistons almost to the top of the deck (milling the block will handle the rest), 3 different solid lifter cams to choose from and a single plane intake. That combo should make about 400-425 hp.

Ok, I saw that one too. They used a ton of expensive stuff in that motor. More so than the W2/tunnel ram combo. I sold my small chamber W2 heads/intake/rocker gear at the beginning of the year. Wish I still had them, but these things come and these things go. At least I sold them for more than I paid.

I'd rather see a 354 or 392 or something than a 426 or a "new-hemi", myself, but hey, can't beat the new-hemi for availability!

It is called a Hemi for two reasons:
1. Marketing.
2. The spark plugs go through the valve cover just like real Hemis did, and are close to the center of the chamber instead of off to the edge like most 2-valve engines.
Really it's just a modern splayed-valve wedge engine. I do like how they put the camshaft so high up in the engine that the pushrods are almost horizontal.

actually, i read up on the 'new hemi', and i do see that its not really a true hemi, and doesnt have the deficiencies of one. however, that just proves my point, which is that dodge is just using the hemi name to fool people into thinking they are getting something better. it shows that you can sell a car to the american public by throwing out some technical **** they dont understand, and they will buy it without really thinking about whether its true or not.
marketing is king, just look at the pt cruiser or the focus. best selling cars, that are completely ****.
for some reason that pisses me off.

the hemi was a really good idea back when everything had side valve and flat top engines, but the pentroof is the next logical step in line. the only reason dodge makes such a big ******* deal about the new hemi stuff is for PR reasons. people remember the old hemis, and how much better they were in their time, so they think that the new ones are better too.
anyway, theres my rant for the day.

www.car-part.com to find prices. Looks like around $8k will get you an unmodified 405HP V8 and a six speed tranny.
To squeeze 400 out of a bone stock LS1 with a tune, you'll need a free flowing exhaust and intake - which you will be fabricating if you're doing a swap anyway.

I think I'd rather have an automatic than a manual with that much power. Makes it a lot faster to drive. No waiting on the transmission, you see.

some hemi info, what the heads look like, the heads are HUGE on hemis. true hemis anyway.

Better to remain silent and thought a FOOL .... than to open your mouth and prove it.
You obviously don't know jack about MOPARS.... or the engineering history surrounding the HEMI's original design intentions, or requirements... Try reading a little....
The original HEIM Combustion Chamber design came from a Supercharged AND Turbo-Charged Aircraft engine design.... The most powerful of its' day... intended for prop fighters. Introduction of the JET age pretty much killed the program..... but the design lived on...

Ya know... Mr Lincoln had a great quote for moments like this:

Twain also said something else which is very applicable to my opinion of you and your reply- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.”
Thanks for playing.

actually, you blithering idiot, not only was your reply to an ancient thread, and not only did it completely lack substance, but Lincoln didn't even say that, it was a gentleman by the name of Samuel Clemens (Mark Twain.)
