Heck, it's so cold here , I'm forced to put on a heavy shirt to play with the dogs in the morning. It drops down all the way into the mid sixties over night! (Last I looked, the a/c was still on, as of this morning.)
Brainstormin' 440 vs 5.9 ...

Sam hopes and wants the best whether it's his way or another. This makes a great human being .... And true, the heads on a BB are a blowed up version of a 350 head .. LOL

A timing cover that doesn’t corrode and put coolant where you don’t want it is a negative these days? Yikes.
5 bolts per cylinder is better than 4.
It's sure nice having a one-piece oil pan gasket and no end seals. 
No doubt, to change the intake, BB hands down for the win. 8 bolts vs 12, and no coolant, and re-use the gasket. But they both have they thing. I don't like the fuel pump rod on BB's. That whole design is stupid. My opinionIt's sure nice having a one-piece oil pan gasket and no end seals.

Never have had that problem here. I don't have to worry about bending mine either.
I also love the cam plate, no button nonsense for a roller cam.
Maybe, with a bigger bore..?
With good deck and head surfaces 4 is just fine on a small block. Gen 3s and LSs will handle a bunch of boost fine with 4. For that matter, early Hemis did pretty darn good in Top Fuel with 4 . My 11.6:1 small block is fine with 4 bolts.

That it is, but I dislike the rear main seal setup. 5,2, 5.9 Magnums have a 1 piece pan gasket.
You got me on the dry intake, even better with a solid valley pan instead of the tin ones, I don't care for them.
With W7 , W8 , W9 intakes, a small block has the same benefits. In a few years I will update my sb in my truck, I already have the block done, and W7 heads are waiting..
Give a guy all the cubes they want, 440 or 512... I wouldn't want to line up against a Mopar Sam small block.
Here is a stout foundation.... [FOR SALE] - Race 360 shortblock !!
There are a lot better small block guys than me around. Several on this forum. Mine only run decent because they know I love them.
You won't say it, but I will. No discredit to any here, but I don't know who is better. You take what was never meant to be, and make it be a HP monster. That makes you a 318WR guy on steroids ! LOL That's why I was willing to line up DT to Ole' Yeller, it would have been my honor to line up and give DT all she had and go down swingin' in losing to somebody that's doing what ain't supposed to be doin' LOL
The BEST thing about Yeller now, is that it is My only transportation. The worst thing is, it likes a lot of 93 gas....
Maybe a 440 Drag Truck against 414 Yeller. Pizza for both drivers win or lose!
I will let you also know....
That DT wouldn't have shown up like she is.... trust me, I had bigger $$ and bigger plans .... Lose? yes, with honor, but we were going to make yeller work for it. I had no plans on serving Yeller a free lunch. Only you, with Pizza! LOL
I don't know if you're serious about the big block heads or not, but no they aren't anywhere near a "blowed up version of a 350 head". The small block Chevy heads all had quench pads, where a scarce few Mopar big block engines used a closed chamber head with a quench pad. The Max Wedges, the 361s, early 383s, (and one year only 350), the 440 with the 915 small exhaust valve head and the 67 HP 440 with the big exhaust valve. All the rest were complete open chamber heads. Chevy never made such.
Pizza is always good, and tailgates make great benches.
this thread has been very on point and productive. I appreciate everyone’s input and with the snow on the ground, it’s a reality now that it is planning time for next spring. I have not made a decision on anything yet, but I would really like when the track opens in the spring that this truck chipped some off the ET.
Well, since there are no rocker shaft stands, Chevy. Plus, they have Chevy accessory patterns on the ends. You think I got turnip leaves stickin outta my butt?
I Notice you skip over all the one's that it had a hard time making 300 hp and less than 1 lbs-ft per cid which is insanely inefficient post #43 finally gets around where 318willrun's engine is ish, then yes after a decent ported head it barely cracks 1 lbs-ft per Cid which is still terribly inefficient. But yes wakes the engine up hp wise (but also barely cracks 1 hp per Cid) and yes would make a good engine for the truck, but will 318willrun build it to that level and if so what would the Magnum do with a similar ported head and cam ? Probably similar hp.

Here's a 5.9l short block topped with an Edelbrock head flows less than IQ52's head but better cam making 448 hp @ 5,800 rpm.

Big block and hole up for a week porting the heads. Imo the 360 is already ahead with having compression but we all know you want to try a big block in the truck. Buy some burrs, do anything to boost the compression within your budget (or go whiplash since it’s for low compression), and pick your cam and let’s see what it’ll do. OR go the simpler route of selling the big block stuff and build a hotter small block and we can keep wondering what if out of the RV 440 lol. Gosh I’m already talking myself out of the big block and I want the big block for you!
When comparing head flow on two different engines the assumption seems to be that if the flow is the same the potential HP and TQ will be the same. I'm not so sure about that. The flow is measured on a flow bench at a standard depression. More depression at the same lift usually results in more flow. So my question is, if you put heads that flow the same on a flow bench on to a 440 pump vs a 360 pump are they still going to flow the same? Edit: And you turn the pumps at the same rpm.

Means we have no dyno numbers, Wallace online says the 5.9 is at 341 horsepower. So the real question is this: What would it take to get the RV 440 over 341 HP??
