The better Mopar street Engine

[greg vess]

What do you guys think would be the best street engine.

1. 440 six pack
2. 426 Hemi

When I say street I mean a car that's mildly geared and in full street trim. If two cars we both identical but the only difference being the engine. What set up do you feel would be the better street machine? What say you die hard gear heads?

I’d go with the six pack.

Never was a MOPAR guy when it came to hot-rodding, my vote is for a D-stroked 400 Chevy small-block - 383. Great power output for size of the motor, capable of running high RPM's (assuming correct internals are used), and reliable/tough.

I agree but we are comparing two Mopar power houses.
The reason I made this thread is because I watched a episode of Engine Masters on Motortrend TV and they put those two engines with the same camshaft setup and headers in the dyno to answer the age old question of what engine would be the best street machine. I so think the 383 is a great set up but with the same size cam I don't think it would touch these two options. We are taking over 500 HP and almost 500 ft. lbs of torque.
On a side note I too love the 383 c.i. mill for a light car that would be altered to account for the lower torque numbers the 383 would have due to the hydraulic roller camshaft set up they used. Also the stall and gear combo would have to be altered dramatically to take advantage of the RPM capability of the 383 c.i. engine.

Not fair! You are cheating! 🤣

These engines had stock iron heads, stock compression and stock manifolds. The only thing not OEM was the identical duration and lift hydraulic camshaft set up and headers. They used the same set of headers they just had to drill different holes in the flanges to make them fit the hemi heads.

Always found the six pack aesthetically satisfying. 😁

426 was a pos with a street tune


But a 426 hemi is my favorite
