I skipped through it apparently his still can't figure out why it's making less than rated stock torque #'s seems like a part III is coming soon :)

Apparently there's a part II, don't if he finds more torque.

Looks like the port shape should work really well, just needs to be bigger.

Shouldn't you be able to mock it up on an engine and mark where the holes should be then drill and tap them.

The dyno test I'd like to see, Eg.. say DV formula says 109 lsa with 65* of overlap, run it against cams from say from 100 to 120 lsa with 65* of overlap, I mainly like to see going tighter lsa.

Well if you go 116 to 108 that's 16-32 lbs-ft but ya go from 110 to 108 not gonna be that huge, 4-8 lbs-ft gain. From what I've noticed on the few lsa comparisons we got, as you go tighter than gains get smaller so going 112 from 116 could get better average gains then going 108 from 112. 110...

Overlap is what can kills vacuum, which is a combination of lsa and duration, people generally will sacrifice lsa for more duration, DV position is to do the opposite, run the required lsa (builds more low and mid torque) and sacrifice duration instead for acceptable overlap. Now I haven't seen...

Depending on top end, especially heads and cam. If you can get the small bore/long stroke to displace enough fuel and air over time (CFMs) the engine will rev, just a bigger bore shorter is more suited to higher rpms.

That's what I was thinking, pretty much on par with LA 273/318 heads.

This is what I found, no idea if true. "It's the RT+10 cam. duration - 272/278 o-lap - 37 centerline - 119 lift - .467/.482 recom. spring - P5249464"

From what I've seen, it seems like the average pay is around 5-7 dollars per 1,000 views, he's got about 90 million total views so about $600,000 over 7 years plus any merchandise. His videos have very little production so he probably don't have to spend to much time on them. They say you only...

Your subscribers numbers generally don't correlate with total views. But ya you would think he'd be averaging at least twice of those view numbers, 30,000 views that's about $200 a video.

That should do it with the right parts. As for hydraulic roller, if you run a mechanical fuel pump you need a roller cam with the right snout for the pump, a set of retro fit roller lifters, push rods, and possibly the distributor/oil pump gear with the right material.

Heads are basically the item that determines and engines available power capabilities, to make 450 hp you need heads capable of 450 hp at the rpms you'll need to turn for your displacement to get there and work with the general cams cr intake exhaust etc... needed for that level. A 340 gonna...

You ain't getting to 450 hp with stock 1.88" J heads.

We aim to please :)

To me the only difference between a 383/440/400 is 0.070"- 0.090" 4.25 vs 4.32 vs 4.34 it ain't that big of a deal for the power most are making.

Is that supposed to be a bad thing ?

I don't think anyone is overly beating on him, I like that he does a lot of mopars, but find most of his builds and videos pretty boring.

Here's a related video that showed up on my feed.

Don't forget they added about 2 points of cr, stock magnum cr to edit* 10.73:1 . Everything thing else was the same other than displacement and cr. 5.9l 305hp/414tq vs 408 334hp/490tq

Is DDG a member here?

:popcorn:

Usually is but a lot of it cause people generally won't run the required gears stall etc.. Most under gear their combos and most seem to run 3.23-3.55 the larger the engine the closer for those gears to be ideal the smaller the further from ideal they become. Eg.. 450 hp 440 vs 383 vs 318...

Why are you arguing ? What your saying makes no sense and doesn't help the OP anyways. If that's what your (imaginary?) buddy told you fair enough but it's obviously bullshit and even if it wasn't the level of proof you would need to present cause of all your past bullshit would be near...

I really liked his "Performance With Economy" book it's out of print you would have to find it 2nd hand.
