Build me a 500 horsepower 440. - 11/01/12 04:40 PM
Its time for me to do my first big block build, and just wanted to get some opinions from people here. I'm aiming for 500 horse, but that's not a firm number. I'd like to drive the thing somewhat regularly so I'd like to keep compression between 10-10.5:1, no wild cams. I figure aluminum heads would help matters as well (which ones though). I know this shouldn't be too hard, but I don't want to end up with a bunch of mismatched parts.

I'd think a 10:1, ported stealth heads, 250-60ish/540-550ish cam, 1 3/4" headers, RPM intake and Holley HP carb should get you close.

Way back noted racer Bill Bagshaw got 511 horse power out of a 30 over 440 with six pack pistons (heavy) at 9 or 9.5 to 1 I forget which, carefully home ported 906 heads with 2.14 1.81 valves using the MP templates and a holley street dominator intake and a holley 750 DP 4779 and 509 MP cam. Went mid 10's in a duster iirc. Dont remember if he unshrouded the valves or not (needed with 2.14/1.81's) nor what torque converter he used or fuel (he would have had no quench)

I'd think this recipe would get it easy enough:
CR: 10.5:1 (since you're using AL heads, should be fine)
Heads: Prepped eddy heads from any of the mopar specific shops (I got mine from hughes, great results)
Cam: Comp XE/Voodoo/Huges/Racer Brown/etc...anyone with aggressive lobes and specing ~ 232-238 @ .050 on the intake side w/ 108-ish LSA
Headers: You'd want at least 1 3/4, but there are so many 1 7/8th's out there that are good quality...
Any of the "good" ignition systems.
Personally, I'd go with a good loose converter (2800rpm) and a mechanical secondary 850HP carb...
That would be an easy 500 hp, with reasonable streetability and killer performance.

Jim Hale had a basic recipe years ago...
Six-bbl. piston under 452's, with a .484-284...
Nuthin' fancy...(If yer old-school)...

The engine in my car started as a completely stock '71 440 spec short block.
With (unported) Eddy heads, performer RPM intake, and a slight upgrade to one of the comp cams xtreme camshafts (it's around 0.490 lift, IIRC) it made about 470 on the dyno. That was at about 9.5:1 compression.
With a tad more compression, and just a little more cam, 500 hp is pretty easy.

Here I'd a build I just did for a customer using his .040 over Speed pro bottom end.
Edelbrock RPM heads with spring pressure corrected,non RPM Performer intake, 850 dp Holley,Hughes Whiplash cam,TTI1 3/4" headers,FireWire rtr distributor and coil.
Not quote 500 hp(491 @ 5300). But torque was awesome .
It did take a lot of fuel curve tuning to get the results,but 450/560 would pretty easy to get without it.
Torque peak hit an unreal 578 and was over 500 from 2000 rpm,as low as I could pull it.

it would be hard, but you COULD build one with as little as 500 hp.

What whiplash cam did you use ?

500 from a 440 is so easy, a caveman could do it!
10.5 compression, eddy heads, intake, carb, cam, headers and you're done.
my 383 block has a 440 crank in it, and is bored .060 over, so it's 438 cubic inches...or, a .010 under 440.
with out of the box edelbrock heads, an RPM intake, flat top pistons at zero deck for 10.5 compression, a comp XE-275-HL (around 230-235 duration @ .050 if memory is correct), holley 750 HP, and regular ole headers, I made 505 hp and 535 torque. my torque curve was also flat, over 500 from 3,000 rpm through about 5800 rpm.
made for a GREAT street motor!

I used the hydraulic HMC3245BL7. Compression ratio came out to 9.22 to1.

You could build it a dozen different ways, the essential ingredients are heads that flow more than 250 cfm and compression and cam to suit. Heck, out of the box Stealths will do that.
Go to
www.arengineering.com and buy AndyF's book. Read it twice.

Maybe it is, but I admire Andy and think he can use the extra $ from a direct sale. That site is his site.

Word. He’s one guy that should be supported directly. Wal Mart, not so much...

Keith, am I missing something here, help me out please. Looking at he graph you posted, shouldn't the torque and horsepower curves cross at 5250 RPM ? They cross at 4400RPM.
Sorry for being

Re: Build me a 500 horsepower 440. - 11/06/12 03:51 AM
The way my dyno program lays out graphs,the horsepower and torque are on two different scales( the torque number is on one side,horsepower on the other).
The hp and tq ate equal at 5250 rpm,its just that with them being scaled the way they are it looks different
Hope I explained it well enough,it makes sense in my head

4.15 stroke. Plenty of kits with them ready to go. After thrashing on one for over 15 years in my race car that I sold, I could only imagine how fun a street combo would be.

Re: Build me a 500 horsepower 440. - 11/06/12 04:26 AM
Is there any way (reasonably) to achieve 500hp with a factory 4bl intake and HP manifolds?
Posted By: Dunnuck Racing
Re: Build me a 500 horsepower 440. - 11/06/12 05:07 AM
I'm pretty confident it can be done,but reasonably would depend on your definition of the term.

The factory engines made 350-375 gross HP. With a bit of cam and compression I think 400-425 would be easy. 500 is a big stretch with factory manifolds. The FAST guys could do it but not cheap.

Neither of you are correct...750/8 = 93.75...93.75x6 = 562.50

Whoops! You're right! I thought it read "cut it in two"! My bad.

I understand what you are pointing out. The graph
on the right is different than on the left.
My dyno sheets from Line Performance read the
same way. My Line built 440 was 10.5 Ross slugs
with Ultradyne 590-613 solid. Stock bottom,
nothing trick. 452 ported heads, bigger valves.
M-1 with 825 Race Demon and MSD was making 590-600
HP range and TQ was around 540-550 all in by 5900
RPM and was out of breath at 6300. Ran on 92 and
raced on B-32. I drove the low 11 sec car every
day for years.
