What about the early years of de-stroking the Hemi to 366 and 396 cid? They seemed to make some pretty good HP!

First, YES IT'S WORTH IT!!! Go as big as your wallet will let you. My 89.5 octane, head limited, 605 made 852hp@5800rpm and 818ftlbs.@4800. It should live a long time and never have to see 6500rpm.
The old De-stroked Hemis made good power too but they had to rev them to the moon.Dave

Yes of course as has been said. I can say I was amazed at how much more low end torque my 493 has compared to my old 440 even though I do have better heads on this eng. But the low end torque is great for a street car that is not a light weight. I can kinda see where you might come from only because I have seen a few stroker cars over the years that I thought did not run as hard as they should but found out as they were built to run like they did. One guy I met had a Roadrunner with a 505 stroker wedge and only ran 11.50's at his best. I thought it should have been faster until he told me he built it to run at low rpm as a street cruiser as he did not want to run it real hard. He wanted to limit it to about 5000 rpm but run mid 11's with tons of torque and he only ran 3.23's in it. It was a nice cruiser on the highway at 70 mph and still ran his mid 11's with ease. But to many it looked like it should have been a stronger running 1/4 mile car. But the owner got what he wanted. I have never driven a Hemi stroker but I consider my 493 wedge a mild stroker by todays standards and it puts one very large smile on my face with its tons of torque. Ron

Completely streetable with stupid power. I would never build a 426 when I could have a 472 or a 484. There is just no reason to.

If you look at flow data for stock Hemi heads and then compare to B heads there really is no comparison. The Hemi has the Wedge covered by a lot! 50-60 cfm IIRC.

Back in the day the magazine tests of 440-6 cars and Hemi cars had the 440 cars with better ETs. But the Hemi heads are so much better, right? The answer is cubic inches. Comparing head flow to cubic inches ratios, the 426 should have been a 526 or something.

In other words the 426 shortblock was just too small for the heads. The NASCAR 7-liter limit made it a 426, and the main reason there were Hemis in street cars in the '60s is because of NASCAR homologation rules. Chrysler was getting tired of having its Wedge engines smoked by the latest ford and pontiac engines of the time, to say nothing of the chevy "mystery motor" with the "porcupine heads".

So, my answer is, even a stock pair of Hemi heads can benefit from a stroker crank.

Thanks for asking.

5" stroke 1359 hp do you think it was worth it.

If the OP wants to turn up the revs he can make pretty
damn close if not equal to the bigger engines... he
might have to turn 10K to what others are turning
6500... a PS is 500" and turns 10k+ and makes 1350 hp
so it all depends what he wants to do AND what kind
of price tag
And to the OP... its not always the engines fault
a car is slow.... the chassis is a major factor
