And check out that 750+ gram piston!
...and you wonder why they had rod/rod bearing problems back then....

Most balance guys (including me) will add in some fantasy number to the bob weight for "oil".
I have seen everything from "0" to 7 grams.
Nobody knows why we do that or what the proper value is/should be.
Sometimes we just do stuff to a target that the machine can provide - even if the target is way beyond the actual need.

A long way of saying "run it"...

FE Technical Forum / Re: Carter fuel pump
« on: March 21, 2024, 05:59:14 PM »
Making a ton of assumptions a 35gph volume is only good for around 450 HP.
But...gph ratings on fuel pumps are often "free flow" - meaning with the outlet line open.
Lines, fittings, bends, filters, desired pressure values and such will all reduce that actual volume.

Again - lots of assumptions - the outlet side of a fuel pump line size is less critical that the inlet side size. 
The inlet side is under vacuum - comparatively low.
The outlet side in under pressure which can be comparatively high.
This is why "in tank" pumps on new cars, running with high pressure, can use such small line sizing.

That .002 seems like a notable "miss".  After double and triple checking measured dimensions I would have no problem using Calico.   They are good folks. 
That type of coating is likely designed to be sacrificial, wearing thinner in high load areas to conform to the bore.

I do like Rory - and just leave that one as a press in plug.  Unlike others it cannot really go anywhere (distributor in in the way).

Similar here.
.0027+/-.0002 on both

FE Technical Forum / Re: Valve stem groove
« on: March 10, 2024, 08:31:47 AM »
Happened on my standard Edelbrock heads with Erson rockers many years back with a reasonably aggressive Lunati solid flat tappet. I put it down to to over revving (lots of 6000's, quite a few 6500's and the occasional zip to 7000, then the valve springs really gave up & I couldn't hit 6!). I covered everything with a shop towel, left individual tips poking through, dressed them with an angle grinder and ran lash caps. They were fine thereafter for many years until the heads came off for a rebuild. Ran lash caps since as I don't think the tips were hardened very well.

Excellent example of valvetrain control damage.  It's like beating on the valves with sixteen little hammers....

Interested if still available

Should not have happened.
Most valves have a welded hard tip - stainless is not easy to harden - and you don't want the entire stem hard.
Ferrea does it on race stuff.
Looking at the side of the tip you should be able to see the change in color where a hard tip is friction welded to the stainless stem.
Rollers do focus all the load on a small line contact area.
I also suspect a material issue, valvetrain instability, or grinding through the tip at setup.

It's been almost 20 years now since Barry_R had the dinosaur in Hot Rod.
I near fell over reading that article.
I feel lucky to have built one of those Genny's. ;D
I hope the FE parts for the next 20 are as spectacular as the last 20.
Reg FE blocks will become very rare as time goes on.

ps: not trying to date you Barry. ;)

Was thinking about that the other day. 
Those were some really exciting years - new blocks, new heads, new cranks.
Miss that time....

Vendor Classifieds / Blue Thunder 427 High Riser Head Casting - one!
« on: February 26, 2024, 05:44:17 PM »
ONE Blue Thunder 427 High Riser head.  Was used as a "port model", with a single hand ported intake port, and a single CNC formed combustion chamber.  Other ports and chambers as provided by BT.  Earlier casting with short OE style exhaust side head bolt bosses. 

I only have this single head. No reason for me to hold on to it, and since castings are IMPOSSIBLE to find, this would be good for someone running a race deal with BT heads to keep as a spare or use to service a broken set .

Has been sitting for a decade or more. 
Dusty with surface fuzz on seats etc.
Never installed on an engine. Open to rational offers.
$1300 or ?

if I am reading their web site correctly, Bear Block Motors looks to have FE heads in stock

He sent me an email indicating that yesterday.
Also said blocks are due in August (!)

Common failure.
Usually from somebody servicing the engine torquing head bolts without blowing out the coolant & crud in the hole first.
Head studs with a bit of silicone and all good.

Not an old Crane grind - but sure similar philosophy with comparatively short .050 duration and lots of lift.
They had a 222ish .607 lift deal back in the "day".
I've never run this one.
But experience with the older Crane stuff was decidedly not positive - serious valvetrain instability at higher RPM.
6500 was a pipe dream....
