I know the difference from 1st 2nd and 3rd generation hemi's, but now all the talk is about 1st 2nd 3rd generation 426 hemi's. Can anyone actually tell me why the 1st and 2nd ones were breaking and what was breaking in them. Are the new 3rd generations ones any better.

I dont want 2 broken hemi's laying on the floor in the shop
Thanks

I briefly discuss it here. It isn't much but I have not seen a whole lot of discussion. Kim

What are you defining as 1st, 2nd, and 3rd? '66-'67, '68-'69, '70-'71??

It is my belief that pre 426 Hemi's are generation 1 --426's are generation 2--- and the new 5.7-6.1 are 3rd generation.
But now all the talk is about the 1st,2nd, 3rd generation of the reproduced 426 hemi's

All I hear is that the 1st and 2nd generation, like the ones Cummings put together were junk.. I cant find out why they were. I realize that a hemi is special but it still is just a engine. What I want to know is what was the problem with the early 426 repo engines. On E bay they are now selling what they call 3rd generation 426 Hemi's built by a race car engine builder. I think it is Sutton racing. I still would like to hear some true life stories of what the problem is with the earlier ones. I am surprised at how little response there is to this as we all have heard the bad press about the 1st repo's
Thanks
Ron

Ron, I see where you are coming from. Sorry, I can't be of help to you. johnRR would probably have something to say about this. He seems to be plugged in on the history of crate engines.

From what I have read, lots of various issues, most related to poor machine work, poor assembly and NO QA.

Hi Rod St Race
This is what I was looking for. After waiting 40 years to get a hemi I only got 300 miles out of it and a rod went out. It was not a crate engine and it was all fresh and I never had it over 5000 RPM Pretty much ruined everything. I thought of a new Crate but dont have the funds anymore. and looking at repair on this is about 2 grand less than a crate.
Starting to think a nice 440 will go in the car. I have bagged many 440's and still own 3 of them Never a problem and when I was young I was nuts.
I babied this hemi and it let me down If it did and the crates are no good then a good 440 it may be.
Thank you very much.

sounds like you got a bad builder. and expensive.

shouldn't cost 13 grand to fix a busted shortblock.


I want my fair share

Generally a 3g is pertaining to a 5.7 or a 6.1...

This is a 3g 426"

Yes all this generation stuff is confussing, but it is the 3rd generation original 426's I am concerned about
When my hemi blew it ruined the whole short block as well as cracked one head. The other is probably damaged as well as there still is a piston cramed up there. I only took parts out from the hole in the oil pan. I dont want to touch a nut or bolt on it till it is looked at.

This is on E bay and for sale as 3rd generation 426

it is item 400006806687 and is a early 426 hemi I cant get the picture to copy here but it shows a nice new 426 early hemi
this is the description on it.

Your issue is with your builder. I realize that HP applications don't get lifetime warrantys, but having a rod let go under the conditions you describe is wrong. The main costs on a hemi are the upper end, so fixing your pile should be cheaper than a complete motor. I would suggest a reliable shop this time. Search around here, and a few names come up most often as the good guys. What do you need: full disassenmbly and clean, block, crank, rod(s), piston, maybe some head work, fluids, gaskets, and a complete blueprinting to make sure it doesn't happen again... did it wipe out the cam? How about the pickup and pump?
