Got a couple of extra parts in a deal for a short block that I don't need.  A cam with low hours that is too big for me and a set of valve covers that I don't want.

Keep in mind these are in DFW, so they'll have to ship.  I have a buddy in Palmdale, so I might could send them out with his Vette on the truck in a week or so.

Comp 11-220-4 Solid lifter with lifters and springs.  $250 o.b.o.  Appears to be low hours, I'd run it, but it's too big for my motor.

Comp Composite valve covers.  Looks like the P.O. dropped one on a corner.  A little epoxy and it should be good as new.

$80 o.b.o.

I've got a set of pistons that are claimed to be Speed Pro .060 over pop ups.  They appear to have a 50cc dome from what I can find online.  They have 292-97 embossed on the bottom of the slug.  I'm still cleaning these and trying to find a P/N for them, I'll post more when they're ready to go.

I don't know.    They have 252-97 stamped on the inside of the piston, which I think equates to a TRW piston, but I'm not sure who finished/sold them.   I can mic them and find the exact bore size tonight.

^^^Some of the info I've found on them.

Edit:  Looks like they are a TRW forging that Speed Pro or Sealed Power finished/sold.  Should be around 12.5:1 comp depending on heads/deck height.

Bump.

On the pistons, I'm leaning more towards them being .030 over.   I measured them with a set of calipers the other day and got 4.268 at the top and 4.300 at the bottom of the skirt.

.067 (1/16th ?) for both comp rings and .193 (3/16ths ?) for the oil ring.

Whoever machined/sold these slugs didn't put a single damned number on them other than the original forging number on the inside.
