    Old magnum MP cam info

    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"

    273 Commando - UTG

    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...

    273 Commando - UTG

    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.

    Tapper to roller cam conversion

    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.

    Tapper to roller cam conversion

    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...

    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.

    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.

    Cost for labor on stroker build?

    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

    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.

    Does this prove David Vizard's 128 lsa formula ?

    Umm this might be wrong lol Say you want an 50 degree overlap advertised and 4 degrees @ 0.050" with a 105 lsa, I'm sure you just add half of overlap to lsa and x 2 for duration. 50/2 = 25 + 105 x 2 = 260 advertised and 4/2 = 2 +105 x 2 = 214 @ 0.050" Edit* just 2 x lsa + overlap = duration...

    Does this prove David Vizard's 128 lsa formula ?

    The question was based on that to run more cr than people are generally willing to run eg 12:1 instead of 10:1 that you would have to run less than ideal timing cause of pump gas. (Wasn’t my assertion) Say for 12:1 ideal timing was 33 degrees how much less than ideal timing would you run (for...

    Does this prove David Vizard's 128 lsa formula ?

    Really DV formula only helps you pick the LSA of the cam, your supposed to calculate the required LSA pick what you figure is the needed overlap and calculate the duration from those two, not really much of an overall cam formula. His overall point is people generally run too much duration on...

    Does this prove David Vizard's 128 lsa formula ?

    No that would be his recommended lsa, for street and or race. Say you like comps xe256h cam on 110 for your engine, to DV that choice basically you'd keep the same basic overlap and cut the cam on 105 lsa with that overlap and that would give you your new duration, probably something like a 250...

    What are you doing for top end ? If your using just the 340 top end (heads) you may gain a few hp, but what your mainly doing is lowering the powerband in rpm, eg.. Say your 340 engine likes 3000-6000 rpm a 416 might be 2500-5500 rpm or less.
