Thinking of buying a new Hemi - Page 3

yes the rear window is flush mounted on a winged car. To do this it requires a fiberglass window plug. all the parts can be found here.

This place has them a lot cheaper but I doubt they are as correct as the others.

a bit of trivia:
A lot of people believe the height of the rear wing was to keep the car stable at high speed. This is false. the the wing functioned just as well much shorter. It had to be that tall so the trunk lid would open.

FF this clip to 6:50 and listen to Petty's 426 in this bird.

Well the 426 Hemi is ordered and due any day now, also got all the kit of fibreglass snout, wing, etc

Can't wait to see the Hemi. My friend ordered it at the local Dodge dealer, they must have been shocked to place an order for one of those bad boys.

His General Lee with new interior.,

Thanks for the update.
Keep us posted.

Hope he has enough sense to have the heads and intake (if not the block too) done in aluminum!!

Common sense, like $$$ can be scarce sometimes. So who knows. We just want an
old timey looking HEMI, alum block?? I doubt that's goin' to happen.

Sorien is a spammer....

Alum 426 block ? Expect to pay 7500 plus for the empty block.
His Hemi will have a very mild Hydraulic cam, electronic ignition and a single four barrel carb. It will be a LOT more street friendly than original 426 and wont require the valves to be adjusted like the old ones. They switched to Hyd cams in 70 and 71
Also the dual fours are a little tricky on the old ones so keeping them in tune is a pain but worth the hassle. You might want to mention to him though to consider the cam specs when he picks his torque converter unless he's going standard. He will probably want something a little looser than a stock converter

Rednine11 · 08-19-2016, 05:14 AM

Is he going to change the K frame or use swap mounts?
Also the power brake booster will hit the valve cover. You can either move it out of the way with a Z bracket or run manual disc brakes using a later model truck master cylinder. Also the fuel line and sending unit in the tank need to be 3/8 to feed it. A Hemi radiator is 26 inches so he needs to measure the opening in the Charger to see if its 22 or 26

Thanks Rednine11, I pay close attention to everything you say and will pass it on. Good to hear from someone who's been down this path already. New to us. BTW your description of what HEMI we'll get is exactly right.

Rednine11 · 08-19-2016, 08:27 AM

By the way, as far as a carb goes. He will want to run an 850 cfm on that. I would go Holley if he dont mind tweaking on them
I have two 750's on mine.

yellowperil · 03-01-2017, 04:10 PM

Finally got an update on the Hemi we ordered. ETA middle of next week. I guess it was only built after my friend committed to the purchase (last year). We shall see if it arrives as promised.

Street hemis respond very well to lots of timing, high compression, racing gas and a bit more cam.

IOW, 700 horsepower.

Rednine11 · 03-02-2017, 04:26 AM

I am running full mechanical advance on mine. I think its all in at 2500 rpm 38 deg full advance. Been a while since I checked it. I just disassembled mine for a cam upgrade. I put in a solid roller Lunati 710 lift 324 duration with Lunati tripple valve springs. That should wake up he neighbors.

I actually had a 1 year old boy patient last week named Hemi.
I kind of laughed and said "did you name him after the iconic 60s Chrysler engine or what, he he?!"
Answer: "Yupp".

The story I heard Garlits tell was, at first he hated the 426 hemi and wanted to stick with his 392 based engines.
He was frustrated with the tuning and couldn't get the kind of power that he was told was possible.
So he got frustrated and cranked the timing up to 50 degrees advanced in a attempt to blow it up and destroy it, but it set a world record.

Quote:

When Don “Big Daddy” Garlits' first 426 Hemi engines hit the track in Swamp Rat VIII and Swamp Rat X, the results were hardly encouraging.

“I carried over every aspect of the 392 tune,” says Garlits, “and that was the mistake. The 426 had large combustion chambers, 176cc to the 392’s 110cc. It took much longer for the flame front to move across the bigger chamber. Plus the brute of an engine didn’t even realize that there was some detonation going on!”

Garlits was well aware that the 392 was threatened with significant ignition lead timing approaching 40 degrees. Sometimes, there were exceptions for the venerable iron design.

“I’ll never forget Bakersfield,” he says. “I had Vance Hunt in the next round. He had borrowed a 392 from Don “Mad Dog” Cook, as his 392 had expired while winning the round. He said to Cook, ‘Do you mind if we put the lead up to 40 degrees for this run with Garlits? We would really like to beat him. It would put a nice feather in our hat. Of course, we will get you another block next week, when it splits the wall.’ Cook responded, ‘You boys can back it up if you like, because it’s already got 42 degrees in it!’ That is why they called him ‘Mad Dog,’ he was crazy!”

The “Acceleration” version of the Hemi in 1964 sported dual 4-barrel carbs.
Garlits eventually dialed in up to 50 degrees timing and quickly set a top-speed record.

Garlits also tried the 392 cam profile but soon realized the engine was begging for deeper breaths.

“Bruce Crower was the driving force behind the cam development for me,” says Garlits. “Bruce was one smart cookie, when it came to cams and engineering.

“Of course, as soon as we found out that the engine was practically indestructible, we really got after it,” continues Garlits. “However we were always restrained by the fact that we were sitting behind the monster. We used to call them the ‘fire dragon.’ Even if it didn’t blow up, you could still drop a valve and put the blower in your face. The Rear Engine car changed all this, and then we really got the full potential out of the 426.

“In my humble opinion, the Chrysler/Dodge 426 Hemi engine, was/is the best production engine ever manufactured by the automotive industry!” sums up Garlits. “No engine, to my knowledge, has the ability to produce so much raw power and still stay together. It will stand forever, as a monument to the engineering ability of the Ramchargers and their team.”

This might be a dumb question,but can a 392 be bored to a 426?I know that there are differences in the block.

No not a dumb question. With bore and stroke the 392 block can go to 417
depending on core shift and all....
