dollar for dollar you will go faster with a 440.

True enough , I keep up to most big locks and beat many , and that is with a mild 340 .You don't even need to "stroke" the smallblock a properly built 360 will whoop *** on most bigblocks

But nothing beats the feel of a big block , it's a different feeling than a small block
Another vote for 408! I like the plug and play aspect of it. There's no need to cut up a good car when BB power can be had in the original SB configuration.
But a fast small block has a better wow factor when it beats the big block:burnout:................big blocks have the WOW factor when u pop the hood.....kim...........

I have both engines, but the stroked 493", 6 pack is in a '70 e-body with a Passon 5 speed. The EFI'd 408 with a 4 speed automatic-overdrive, lock-up/3000 rpm stall torque converter and 3.91 gears is in my '68 Barracuda convertible.
Both are quick and fast, but the '70 is much more so, as it has a touch over 700 hp, and is a handful. The 408 has just under 500 hp, is a blast to drive, gets better gas mileage (15/20 premium) versus (10/14 w 101 octane unleaded) and can is better suited to daily driving.
Either motor could have been built stronger, but street manners outweighed the chase for that last chunk of top end power in my builds. Both cars have smallish hydraulic roller cams for that reason. It was a good trade off that I appreciate every time I drive either one of them.
You really can't loose either way you go. Especially, if you run an overdrive and possibly even fuel injection. I may even convert my 493 to EFI soon. I love EFI.
It's like this:
B cup tits are fun! They do there job and everyone loves em.
DD TITS ARE AMAZING AND EVERYONE TURNS AND WATCHES EM GO BY.
Enough said
I had almost exactly that in a 3,500 Lb. Dodge Coronet, 2 Dr. Post Car and it ran in the low 12s. I drove it on the street, almost daily, in the summer.it only takes a very very mild 440 to get you into the 11's. I bet you could build a stock bottom end 440 with mid range forged off the shelf piston for allot less then the 408 bottom end. it takes nothing to make 425-450 hp with a 440.
stock bottom end rebuild with 9.5:1 pistons
comp cams 294s cam
stock 906 heads with decent valve job (bowl blend would be nice)
performer rpm intake
750 carb
1 3/4 + primary tube headers
3:55-3.91 rear gear
3500+ stall converter
done deal.

Just out of a curiosity, how does a souped up 440ci small block with great air flow and equal compression compare? The small block has more stroke-doesn't that help with street-ability in regards to equal output?
What's his face ({BPE/BME??} am blanking out, asparatame? CRS?) sells the 4.125 or 4.25 cranks for the same price as the forged 4 inch cranks.
What about 440ci SBM? Is it really so unattainable?
I don't think we can get the over-bore from a magnum blocks, people have over-bored 340's & 360's a hundred thousandth's...
RAM says he doesn't like the 4.25 ?rod ratio's?? Wear on the bore??
Is this the anchilles' heel answer to my question?
