Question on the modern hemis?
So I like building sport trucks and just for fun in class a few days ago I was talking too one of my instructors and he mentioned too me throwing a new modern hemi into a 99 Dakota instead of a doing a big block build which at first I didn't really think much of but then I started thinking about how much power the new hemi can make and how they aren't wallet killers on gas so I guess my question is out of the new modern hemi what are really there weak points? have any of you guys every really built serious power out of them? and by serious power I mean around 500 or 600 to the wheels and not have any major reliability issues I was looking at the 392 and 426 HEMI if I was going too do a swap like this

Front balancer, pistons and connecting rods are suceptible to big power stress at 600 + anyway.

The aluminum blocks from Arrow Racing Engines are good! They are the development people for Chrysler's/Dodge Viper and Drag Pak Upgrade (DPU 426) engines. It's about an extra $3000 for the 100 lb weight saving.
You can do whatever you need to with an iron block. Parts wise, getting a junkyard engine for all the peripheral parts would be a good start. Arrington Engines offers all sizes of short block assemblies for your interest. |

Crazy4carz built a 5.7 stroker for his 68 Dart some time back.

What if I pulled the motor tranny fuel pump and etc from an old wrecked charger or challenger do you think the parts would work with the swap?
A 727 and a 904 are a direct bolt up option as well, just need a conversion flex plate from MOPAR. A newer transmission takes a big tunnel to fit it in. If you get the wiring harness and computer, you may be able to harvest the wiring you need and junk the rest. Otherwise, it's a good $3000 +/- for a aftermarket ECU and harness. |
