without an overdrive, anything lower than a 2.94 for the rear isn't daily driver friendly, especially if you go on the interstate at all.....
with an overdrive and 26-28" tires, a 3.55-3.91 is about the max....
and a MP 509 doesn't sound very DD friendly either.. [Email]224-230@.050[/Email] is about the max I'd consider for daily driver cam duration for a motor in the 340-440 cid range...
I gave my combo as an example of how good a mild combo can run. Take some gear, cam, and converter out of it and you'll still likely have a 12 sec car.

Rebuild your smogger 440. Run a cam in the 224-228 duration range, wider LSA (112 or 114) and split duration, headers, aftermarket intake, hemi stall, 3.55s. If you shave the heads and make sure you have a true 9.5:1 compression ratio I think you'd hit high 12s for sure. If the budget allows use a six pack set up, but those are easy to toss on later.
Spend a little bit of time opening up the bowls on the heads. I think this would be the cheapest and most reliable way to go in the long run. Stroker LA engines are cool and can make some serious power, but with a 4+ inch crank (and a really short piston to use it) I don't see how those things can last nearly as long as the 440. A big block is a tougher engine to start with as well, but they're all made well.
Now I need to pin those needles, got to feel that heat

This car is driven to the track, raced in 2 classes so it is hot lapped, runs on pump gas and its not a stroker, just a 340 full interior steel wheels change the tires at the track to a small slick, 1.60 sixty foot with slant 6 suspension,
runs 11.90s all day!

given your current parts, if you're not willing to start out with buying a magnum 360 core motor, I'd use the 360 block, stock crank, rods with good bolts, KB107's, RHS heads from brian at IMM, and a lunati voodoo 60403 cam. I'd be tempted to go with the magnum style heads to run cheaper (small block chev style) 1.6 ratio rockers. for rockers I'd probably look at Scorpions. intake, either redrill the heads to LA pattern, or run the magnum air gap.
if you're running 26-27" tires, I'd go with 3.55's and the A833OD. has a deep 3.09 first gear to get off the line, and should cruise at 70 mph in the 2400-2500 RPM range.

stock 360 - small valves and an eddy tunnel ram
3.23 gears and a 904 with low gearset
16 mpg on the highway
12.56 best et
108 best mph
i think alot of recipes listed better be in the 11's or somethings wrong with the build!
I agree,my mostly stock 360(except for cam and heads) runs mid to low 12's easy.
gears and vehicle weight have a lot to do with it.
true, but 4.30's, 3500 RPM converters, [Email]240-250@.050[/Email] cams aren't exactly street friendly....
another option if you want a daily driver that runs in the 12's? get a 300 SRT8 (:
the iron case A833OD should live if you don't hook hard...
mine has 3:73's and a 2400 converter,it is very streetable and can be driven anywhere anytime.
