D150 with a RV 440, just to see what it will run

-
Except as Rusty pointed out, it's not really a stock motor home 440.
An intake and carb is mildly modified? Not in my book. That’s Honda guy rationale, it’s “fully built” when it has a fart can and an open element hot air intake. His 440 is still pretty damn stock in my opinion. The intake and carb are likely not too much better than the factory 4 barrel intake and TQ. Dare I say the torker is probably worse down low than the factory intake?

Thank you for bringing rationality back ... and common sense :)
 
2026, new thread

We here at 318willrun are looking to install a RV440 into a D150 long bed just to see what time it will turn at the track. Here are the basics:
  • 1980 D150 long bed. Weighs about 3600 lbs by itself with the small block. Will have cheap headers, cheap off the shelf hughes converter (currently behind the 360), and a gear that fits the low revving 440. Right now, the truck has 4.30's, but I doubt the gear will be that steep for the 440.
  • '77 RV 440 with a torker intake on it. We dealt with one rusty cylinder (drill honed and put new rings on that one cylinder), heads are fresh, Carb will be a Brawler 750 DP because that's what's on the current 360. I won't be doing any "upgrades" to the 440. I want to see what it does as it sits.
Here is the truck.....

looking forward to your pass, got to make a pick in this horse race.
Let me tag my son @MeMikieJr

wish you had 3.55-3.73 available lol. I’d be curious to see how it does with the 3.23/3.91.
3.55 hope he has a good tire and gets some practice in with the pedal race.. agree ..3.55 would be choice, but it would run threw the power ban quickly.

Good morning @318willrun , put me down at

Hoping for a good light, good bight and not over revving past power band..ah...
14.27 please

My son and I are doing a 5.7 Hemi, trans and drive shaft 2014 install on a solid bones, Zero rust 1988 beuity

i listed how it's going to run. Did you make a guess?? Make the trip over and watch it run! :)
I think people are just getting too intimidated to go through 13 pages of posts now... You've made it clear from the beginning that it's a stock long block motorhome 440; anything non-factory (headers, torque convertor, intake) is just to accommodate getting it installed and running, and any performance enhancement is purely incidental. Honestly, I think anything you gain from that wouldn't be any more than someone would get from having an engine "blueprinted" to stock specs. $$ and not the point of your exercise.
Have fun and ignore the nit-pickers.
 
An intake and carb is mildly modified?
Intake, carb and headers. I think those items would be considered part of a mild build. It's the starting point for most performance modifications done to a bonestock engine. These modifications are fairly easily done " over the fenders" with a minimum investment in tools and knowledge. This where many beginers get their start in hotrodding an engine. That being said yes it still has a stock camshaft in it.
The intake and carb are likely not too much better than the factory 4 barrel intake and TQ. Dare I say the torker is probably worse down low than the factory intake?
That's the question that I find interesting too. Would the stock configuration be better or worse than the mildly modified version currently going into the truck. Apparently it's a hard no on answering that question. Too bad since the carb, intake and header combination is where so many, especially beginers, start. I think it's a missed opportunity to help others determine if the juice is worth the squeeze for some one installing a rv 440 in their a body or other choice of vehicle who is considering doing those modifications. It was just a suggestion. One that was a different direction than what has been discussed so far and something I thought could be helpful to others.

and what would my truck headers tell you about A body headers??? Price and design is totally different. It would NOT help them make a decision at all. My headers were well under 200 new. And the design would perform differently as well. Same with truck manifolds vs A body BB manifolds. I put headers on my 318 van and showed the difference in ET. They can watch that for a stock engine comparison from manifolds to headers. It's on my channel.

And by the way, anyone that's putting a stock RV engine in their truck will probably use headers anyways. Those that don't, probably don't care about performance or what it would run.

My suggestion wasn't to change what he has already planned and or made clear that he is going to do. I was offering an idea for a "next step" that I thought would be interesting, fairly inexpensive compared to the other next steps he has been throwing out for consideration and helpful to someone who might be doing a rv 440 swap on the cheap. For example if it turned out like tt5.9mag suggested that the stock parts were faster or as 318 will run claimed that they won't really make a difference then it could save someone else the head ache and money. And as a bonus a chance to win another prize .

You do realize I have completely side stepped my "moving forward to make the truck faster" for this project, right? This will set back the trucks purpose several months. You want me to bring it home, remove exhaust and intakes/carbs, retune it all, go back down to the track, etc. Think about it my friend ...

It’s definitely an interesting comparison. And in my head a dual plane with a TQ will be better than a single plane and a double pumper on a stock mh440 that only spins to 4500rpm or so. I like your thought process. Hopefully we’ll see a round 2 and that can part of the plan

Yes!! You do all the work and we reap the rewards! See what happens when you’re a master tuner!?

This is what exactly happened to the low dollar 318 Duster. I did the low dollar project, did exactly what I set out to do and hit the goal. Then, of course, the masses wanted to see what it would do with headers, gears, converter.... Much of my time and money later, they saw but I never did get the magnum built for it, and it's sold now.
 
Yes!! You do all the work and we reap the rewards! See what happens when you’re a master tuner!?
My money, my time, my parts, my sore back and that blood blister that always happens you know... I donate it all for the cause... LOL

oh, you will see part 2 !!! But it won't be going to single exhaust and a cat !!! LOL
 
The stock motorhome/RV cam negates all other changes except for the tuning. If it were any of the longer duration (350, 360, 375 hp) cams being used then the manifolds and headers would constitute a performance improvement over stock. The torker 440 probably won’t perform as well as the dual plane iron intake with the factory spec broomstick, but the weight reduction with the aluminum intake will make that a wash. I’m looking forward to seeing how much gain a proper camshaft makes on the follow up trip to the track when that time comes.
 
15.4 with a nice smoke show.
Got you added! Thanks
