I believe we have an engine builder
@IQ52 here too
that said the same thing I said about '
Out of the box flow #'s'
Chinese castings from Stealth/440source
vs Edelbrock "Made/Cast/Assembled in USA"
he may chime in too
I don't have an agenda here
I'm not 'trying to sell' Steve anything
just an honest 1st hand experience with heads
honestly, I wouldn't sell him anything
so much for an honest opinion
I dunno if anybody is really skirting the Law ? as merely working somewhat within that somewhat flawed "Law" maybe ?
Anyone.... please feel free to correct me here as I am NO expert !
That said...
my understanding is that to be able to put "MADE IN THE USA" on your entire product line like Edelbrock does..... with "castings".... the regulations state that at least some "percentage" of the TOTAL number of Castings must be made within the continental USA.... the remainder may be "contracted out" offshore.
I think.... because I don't know the exact percentages ?
But IMO...
something like 20-25% of the Castings must be done in USA at a USA Foundry.... in order to put "MADE IN THE USA" on ALL of the 100% of Castings Sold.... even though 75-80% were Cast at a Chinese Foundry.
Can't blame anybody.... it was Congress's way of maintaining at least 'some' casting capability on US soil or it ALL would have gone offshore ?
I've been there in San Jacinto Ca. Foundry
& to the Torrance Ca. facilities & seen them, 1st hand...
Had lengthy talks with the onsite engineer there & on the phone
when they were developing them...
I saw them casting I don't know how many
maybe 10's of thousands on racks...
Raw castings waiting for machining...
It's 100% Made in the USA castings...
100% made in the USA parts, valves, retainers, locks & springs
or seals too
unless something has severely changed since Vic Died
I haven't been down there in a few years now
if anyone actually
gives a rats ***
don't listen to the lies/liars "I think, isn't facts"
take it how you may, trust who you will
I've seen heads on the flow bench, 1st hand
being tested, by my old head porter (Mark Rowe, RIP)
that were or nearly exactly what Edelbrock, claimed they were too
within 1-3 cfm on the 2 sets of RPM heads, I brought him
I got/bought from Summit Racing...
I also saw or Eyewitnessed him do a set of Stealth heads the same day
in back-to-back comparisons. I had a set still in the box too...
Replacements from 440source for heads that were replacements
the "Chinese Cast" Stealths had a lot of issues early on...
