im gathering parts for the 440 swap for the Dump Truck and seeing I already have the Comp cams XE256H cam and headman headers and my good 9006 Thermoquad is it worth it (Power wise) to spend the $255.00 and put a Performer 2191 intake manifold on this mild 440?

You would not think that being a 5670 empty weight work truck that it’s needed but:

it’s geared deep, in the order of 4:10 or even 4:30ish and the TF 727 has the smaller torque converter for higher stall
AT 65 mph your turning 3-3100 rpm empty and loaded it’s more like 3400-3500 rpm (360 powered)
When we get landscape rock and fill or black dirt the hwy min speed limit is 60mph in 1/2 mile after ramp and I did get a traffic warning ticket for taking longer than the .5 mile

So I guess what I’m asking is Performer worth enough power over the stock to make it worthwhile?

we were loaded with 2.25 yards of 1 1/2 inch landscape rock for a total of 14,378 lbs and on the uphill ramp with 2 more miles before level ground. The state patrol told me I would need red flags and 4 way lights on or find a different route,

We have a non efi 93 Chevy dually with OD automatic with a stroker 427 Truck engine(496) that has a comp cams 260H cam and Holley 650 carb that pulls that weight at 2400-2500rpm and a 98 Chevy crew cab that was 7.4 efi and is now 402 based stroker(434) that with cam/intake/headers puts that efi 7.4 to shame towing as it will hold OD gear even with the skid steer and attachments(13,531 lbs) that the efi 7.4 couldn’t.
Both of those engine were built at Robbie’s Machine shop and set up and tuned on his dyno.
That was almost $5000 per engine which I’m not doing this time.
That has convinced me no to think efi is a power adder but more of an ease of tuning thing.

[QUOTE=crazzywolfie;3383787]ah that would do it. almost sounds like you had the truck overweight by quite a bit if it was weighing in at that much.

Last load of the day, just enough to finish the job and yes, around 2800 lbs over the gvw posted above the door.
what I,m saying both the carb motors that were dyno tuned are just as smooth but more powerful than either the OE diesel now gasoline 496 in the dually or the port efi 7.4 in the crew cab that is now a carb gas 20 cid less engine. All of my GM trucks are built 4L80E trans with 4.10 gears that are ok (per mfg)with towing in od
EFI is normally way easier to tune and yes, self learning and you can feel the difference in the but dyno over most old well worn not dyno tuned carb engines If you ever take a carb 360 truck and a 5.9 magnum truck the magnum feels way better but it’s 90% heads and more compression and efi for the smog police. Dyno tuning gave me the best tune you can get with a $600+ change invoice per engine and a so-so tbi is around $1000.00 and that doesn’t get you ignition control with knock sensor so I’m looking at +$2200 to do that, which is still tbi, to me a glorified carb.

With the 9006 Thermoquad which is already jetted for 440 I’m wondering if a Edelbrock Performer intake is worth 10-20hp and 20-30ft/lbs over the stock egr cast iron intake on the engine

Over the weekend i ordered the 2191 Performer intake on advice of the Mopar Guys in town. This is what they said:
“on a stock engine or up to 204 or 5 at .050 OE is fine, but when you get a little over that (cam size) you need more pleneum volume and your at 212. @ .050 where the stock intake will only be effective to 25-2700rpm. After that, your leaving more on the table and by 3500 rpm you’ve lost around 15 hp and 28 in torque or so”

Thanks everyone for your thoughts on this!
