Engine Master block assembly
« on: October 14, 2018, 11:38:35 AM »
Already sold the heads.
This is the bottom half.
Parts are used - not broken - but used

Crank is Scat cast 4.125, Rods are Scat 6.8 H beams piston are (I think..).Diamond for 4.25 stroke with a thin ring pack, lateral gas ports, and skirt coating - and have has about .020 milled from the top to work with .066 Cometic gaskets.

Cam is a custom Comp solid roller.  This one is short duration and I can swap in another " bigger" one upon request.  Timing is an adjustable set under one of Jay's timing covers.

Pan is Ford C8AX in really nice shape with normal Melling and ARP bits in the appropriate places and a Romac damper.

Block is junk.  Early Sideoiler Garage/Genisis piece.   Starter side is a puzzle put together with stitch pins, braze, epoxy, and paint.  Block is filled 80% and it still leaks water.  Never any water in the oil, makes good power and lots of dyno pulls at over 650HP so it must be structurally sound.  Someone like Hot Rod might be able to weld it, you might just fill it to the decks, or you might try a bunch of GM stop leak tablets - caveat emptor.

I will take $5000 for it as is.  If you add up the parts you will see that its something approaching a free block to take a gamble on.

I could be talked into splitting it up

Still no sale as an assembly - so it comes apart.
Anybody interested in a used 4.125 stroke kit with 6.8 H beams, and the rest?
Requires .066 Cometic gaskets
Balanced & ready to install into your block $1500....

Even your junk block is better than my Sideoiler Garage Block. Has never been supplied from Tim despite paying for it 18 months ago. At least you have some metal in front of you.

So you haven’t had any resolution either. I wonder how Tim Mcloughlin sleeps at night?

Barry, piston size and expected compression with the suggested gaskets? With the cylinder wall I just kicked out, I'm thinking about prepping another 390 block I have that is currently std bore.
