Sweet
Great numbers
Much milder than a comparable 408, mild cam and 9.4 comp, the trick flow heads shined on this 383 build.Not bad, 408 numbers with what a lot consider a throw away engine
Thanks. Mr. Salter proved what I have always said, “Lift that valve up as much as possible if the head can support it.” That head can support the .600+ lift and power numbers paid off.

the 383's 4.25" bore helps too compared to a 408.

Killer mild street build. That guy has an awesome reputation. Wonder what it would make with a hotter ignition system.
That and a ported RPM intake, it wasn't a fair comparison for the RPM going up against a ported torquer.
The RPM and Holley street Dominator are the absolute best for the low deck, OOTB and in ported form.
And a shorter stock stroke than a 350 Chevy.
I didn't notice, was the 383 stroked?
I'm not convinced till I see an apples to apples test on those 2 manifolds. Ported rpm airfare will only flow 230 fish cfm and he didn't post any flow numbers for the worker and the heads.
So it may or may not. Show me.
I
Trickflows single plane is a good manifold as well
280 range OOTB.
Hotrod did a manifold shootout on a 383 mule.
It's been common knowledge for years the Holley and RPM are the manifolds for the low deck.
I imagine the Trick flow intake is probably the top of the heap now.
We already have.

Admittedly, I did skip ahead several times while watching, but my takeaway was the manifold comparo was the reworked original Torker vs an ootb RPM.
Was there discussion/video of porting on the RPM and I just missed it?

Snapshot of the end…….
At the top of the sheet there’s mention of swapping vr1 20/50 for Mobil 1 5/40
It would be nice to see the best sheet with the RPM, to see how the numbers compare in the area of the curve below peak TQ.

What's the $/ci ratio between Chev vs Mope on this one? J.RobNot bad, 408 numbers with what a lot consider a throw away engine

Mr. Salter proved what a lot of us have always known. You need to work your tail off AND have a wheelbarrow of $$$ ( think TF heads on 383 here) to FORCE a 383 to make comparable power to a SBC mouse motor. J.Rob

So why do most 408's absolutely trounce this admittedly max effort 383? J.Rob
Do so and looking forward to it.
Please explain
MoPar is always more. Nothing new here. Why even bring it up? For those wanting to do a MoPar engine, they will do it knowing it’s more expensive and don’t anyway. Why are you bringing a Chevy engine into this?
Chevy being the cheapest of all. We know this already.
“Force” this I don’t get.
More cubes equal more power.
How do you see it otherwise?
I haven’t seen any 408’s run a cam as small as he did and at the compression ratio as well. Every 408 I have seen is almost always running a sizable camshaft.
The smallest cam I seen a dyno sheet for was running a hyd roller at 224 or 226 @.050. That’s a small cam for a big engine.
