As it was said before, 440's will have the upstair
power due to it larger bore. things will will be tight between them at low and midrange.

---

Still wrong on all counts. The 440 will crush it with low RPM tq due to the cubic inches and it will smash it on top end because of the ability to flow more air with a bigger bore and less shrouded valves. The low RPM TQ is a direct derivitive of the cubic inches and the 440 will kill an equally equipped 413.

---

um WRONG. small bores BIG strokes.. thats what wins in a killer street engine. being of EQUAL cubic inches mind you.

JUST FOR AN EXAMPLE:
TOP FUEL ENGINES:

4.1875" bore x 4.500" stroke

remember kids.. just an example.. i know that isn't a street engine and its supercharged, but
yet they choose to make the engine that way.

Following YOUR logic... If the smallest bores and longest stroke makes the most TQ and TQ wins races then how the hell come we don't all run 225 slant six's and slaughter the competition? Bet you didn't know the 225 had the longest stroke of almost ANY engine put in a car since about 1960 and one of the smallest bores of the muscle car era, the smallest bore and the longest stroke, and to further make it the king it has the smallest valves and ports of any mopar motor from the muscle era... it should even kill the mighty Hemi any day of the week ! Heck if only the 18 wheelers knew of the 225 they could save all that money on 1000 cube catapiller diesels they run. The fact is your logic is completly wrong, the 440 will make more TQ because it has more DISPLACEMENT. No one ever said a 413 is slow so you need to quit repeating it, re-read the post genious. The only things people have said about it are it will make less TQ than an equally built 440 and pistons are expensive customs or expensive lo-po replacement pistons and you could buy a 440 and build it cheaper and make more TQ doing it. Stop trying to put words in peoples mouths.

Dave, I think the BUICK CAMP disagrees VERY
LOUDLY. (My apologies to my MOPAR brothers).
SAME BORE, longer rod?, LONGER STROKE. EXPLAIN
TO ME WHY 440's Have a hard time, with the GS's
and Skylarks, or even a some 2-door ELECTRA 225's
built to run deep 10's, legal and driven on the
street regularly. Dave, your problem is that you
are scared to 'run the opposition" cause your
combo isn't sound. Or, is it that you have spent money in it and "think" that it is the ULTIMATE.
I am waiting for the day when some person (man or
woman), shuts your combo down. They problably will
have done their "homework" on their combo and spent "less" than you. They may have checked over
and over, the balance, clearances, parts compliment (intake, carb(s), cam, compression,
exhaust, gears/tranny and suspension) and most important vehicle weight. Not rocket science, just
plain ol' hot rod innovation. Enhance what the factory gave you, improve the weak points and
exploit the strong. You so caught up in your
rhetoric, you may get beaten by a MAX BORE, HI
RPM 400 Mill in a 2800- 3000lb chassis that is street legal. I do know a few. AND they are not
"HIGH DOLLAR" combo's either. Read: non stroker.
One favor though watch who are calling the "post
genius". I try to help those who seek knowledge
"without engine discrimintion". You, always been
the self-rightous proclamed 440 GURU read "THE
UNBEATABLE", do not respect the opinions of the
other member of this post. Offer a little
constructive criticism some time, open your ears
and maybe, just maybe you WILL realize the 440
isn't the ONLY GAME IN TOWN!! It is a GOOD mill
but not THE MILL.
