Most mopar heads stink in stock form, including edelbrocks, when trying to feed even a 360 engine.

There are decent heads that will make good power, IMM LAX iron and likely the new trick flow pieces. Other than those that are stock style replacement heads, you're going to be spending $ on porting to make power.

Have to get the air in and out. Would you run a marathon breathing through a drinking straw? That's most SB mopar cylinder heads in a nutshell.

Absolutely true... and with better heads the stroker will bring you from 375 to maybe 500 horses (Mopar horses, not Chevy).
And it still will be a simple drop in, in contrast to swapping to a 440 that weighs a ton more and is a much tighter fit.

I built AND tested my first 408 way back in 2003-2004. Mildly worked some J heads and put a healthy solid cam and 273 rockers on it with an Edelbrock Torker manifold. Made a mind numbing -LOL 465 HP @ a(warp speed) 5200 RPM 528 TQ @ 4300 RPM-felt big blockish for about a second or two on the street-and was not really any more fun or quicker-on the street than the 367 (381hp/417tq) that it replaced. The 360 was so much easier to hook up and revved like a chainsaw in comparison-don't get me wrong here the 367 could melt the tires at will. The 408 was very difficult to launch properly and it had a MOMENT of greatness and then it was over. Gonna stroke it? HEADS, HEADS, HEADS. Unless its for a boat or a tow truck but then I'm on the wrong forum.

The EngineMasters test is not a surprise whatsoever and everyone falls into the trap of TORQUE-TORQUE-TORQUE. Problem is the pendulum has swung way too far the other way. It's all about balance and without balance the driving experience is diminshed greatly. J.Rob

p.s. Don't go bigblock-refer back to balance statement, it applies in more ways than one.
