Manton PR 'example' and B1 piston modeling

Fitting new o-rings before I file them flush and guard-dog pic.

So I take it the B1 piston valve reliefs will work with your Indy 440-1 heads?
Did you take a picture of the clay after turning the motor over?

Hey Jim! The pics are confusing because I was considering the domed B1 pistons with the other package 572-13 top-end. The pic was taken AFTER i spun it over with about .060 piston to 572-13 head cold...plenty of dome to chamber room.

Just to not add any confusion because of other assembled engine pics on this post. This is what the engine will look like when done, the only visual difference will be the aluminum block...

at least your guard doggy isn't asleep...........
a question though, why a small block damper on a big block, although you have the timing mark where you need it. was the reciprocating assembly balanced using that damper, or are the damper weights the same [or close enough] to be able to be swapped ?
just trying to learn something here.

It's a neutral balance damper...i just wanted to locate the ZERO in a visible place.

thank you sir.

Removed old SS .045 o-rings from deck...that was fun? Replaced with copper and filed down flush...

Because the new Scott Brown cam I went ahead and made the geometry as good as i could. Which, as mentioned earlier, required a few other 'adjustments' including rocker stand bolt shortening. One protruded in the port roof the others were for the paired rocker hold-downs on the stand themselves.

The stand hold-down bolts on the ends were an odd-ball head diameter and short-height so i ordered some longer ARP 7/16 from Allens fasteners and trimmed them on the lathe.

After sorting this all, I ordered some 7/16x.168" straight-wall pushrods from Manton with .040 restrictors. I had an intake manifold flange from my buddies 1400HP single-4 565" BBC and laid on the deck-surface to gage why his makes so much more power than my 440-1's (in the background)

I pressure tested the 'repaired' KB block to learn it had a few significant leaks and a small crack. Then the fun stuff started as i was welding repairing it the gas quit working/flowing on my old Lincoln square-wave., Once I got that working again I was chasing leaks and cracks. I think that's finally done but yesterday after the last welding i didn't do a final leak ck.

I took the block over to a better welder with better equipment, the external leak is fixed now but it had small leak now around the sleeve into the crankcase so I got creative. After a good cleaning/prep, I vacuumed Loctite 280 into the area.

Moving along I mocked-up the old intake to port match which took a little grind/widening and then a little epoxy because the new heads have a large radius at the corners..

Opened bores to near 4.500

During leak test the deck surfaces appeared to be leaking? So i hand-lapped both heads decks smooth/the fun that was.

Installed height was not measuring 'right'. I found the spring seats were interfering at the radius of the guide. Once that was fixed, I had to touch each intake seat about .010" to get spring coil bind where I was comfortable.

Lots of ways to skin a cat but this pic probably needs no explaining. Got to have ACV daily!

More diff ways to skin a cat, I use 2 of the upper row head bolts to anchor the head to bench and use the typical in-car jesel spring tool. Also tailored the rocker bar bolts to length on the lathe.
