The headers lose most of the tuning and scavenging benefits operating
thru the mufflers have is my observation.
Bach in the early 60's when I was a poor kid (still miss those days), I
would install cut out a foot or so below the manifolds on my Mopar
and pick up a tenth or sometimes more at the...
You can make horsepower thru the exhaust manifolds.
However, all the FAST Mopar that I am aware of have significant work
on them including extrude honing plus portingand cost more to do than an average
set of 2 Inch headers.
When I tried the HP manifolds on my 10 Second 440 Valiant, I lost 3...
As I recall, back when I ran my Factory 68 Hemi Dart,
The jetting that came in the factory 770 Holleys
was pretty close at Sea Level and a good start.
Is it a dedicated race car or a street car that runs thru mufflers
and real Air Cleaners?
Nope, lifter weight to me is not all that critical
compared to the rest of the valve train in my opinion.
If I break a lifter, then the engine goes to hell in a Hand Basket!
Quickly.
Just my .02 = For Free
(And probably what it is worth)
Thought they might be Ford 875 looking at them.
You will need a Long pushrod and depending upon the

This is quite a small camshaft.
I would rather run an older factory camshaft that

NOS early Mopar Performance camshaft kit on the forums.
The new Chinese cams are questionable at best.
I sold over a dozen old NOS of the Mopar Perf...
I run the Milodon Cover with the rear entry.
I could not use side entry because of clearance.
I have several systems and individual pieces spare i
you need one. I would sell them 1/2 price of new.
I too had issues with the 440 source part with erratic
oil pressure.
IF = This is a brand new rebuild I would be
very concerned about the rings sealing.
I NEVER let my engines run over 140 during break in
for the first 10 or 15 minutes. Harbor Freight has cheap
temp gauges to point at the radiator.
I have sold good core blocks for $375 for many years.
Still several sitting in the shop. That is really about the fair price
around the West Coast. The main trouble with Motorhomes is they
are impossible to scrap and no wrecking year out here will take
one when you are done. I have to get a...
RB Block.
Fits Max Wedge Heads.
$400 to $600 if someone is needing one.
I miss seeing you at the races my good friend!!
Thanks for all the help over the last 30 years.
Jack and his brother were racing Max Wedge Cars while
I was still in short pants.
No more Honest Guy to deal with that you...
