Tell me more about this "electric choke" version. Is there a mod kit available for non-EGR manifolds?

For those of you using the Edelbrock heads on your smallblock...any considerations with regard to head bolt kits, gaskets, rocker arm shafts or any other things that might not be mentioned in literature on these heads? In other words, are they plug 'n play as far as replacing cast iron heads...

Bummer. Has the block already been bored .040 over? if so, then the choice of pistons will depend on whether you want the lightest piston available (hypereutectic) or the strongest (forged) along with cam/compression compatibility and profile (domed, flat top, cut for valve reliefs, etc). Just...

Sounds like you are well on your way! What your 3 things add up to is pretty much personal choice. What does your engine builder suggest? Carbs are pretty much a personal thing; I'm a Holley guy myself but to each his own. And a carb swap can be easily done if you're not happy with the results...

I think they look great! And the Tri-Y's have a good rep among Chevy aficionados. Only thing I can say is run 'em and see how they compare.

Rope trick works great. We do it in aviation all the time.

No worries. There's more than one way to skin a cat, I reckon!

No doubt they work, and likely pretty well on a strip or circle track motor. But for a 50 year old street car that gets the oil changed every 5000 miles or so...and you hope to get 100k out of...I would still recommend bushed rods.

How often are those engines torn down, though?

If you're going .030 over you might want to have it ultrasonic checked depending on cost.

It might "work", but then you have no sacrificial metal. Wear occurs on either the rod or the pin. Or both. Something has to give, and you should prefer to have it be the inexpensive bushing that is easily replaced. If operating on a tight budget I'd look for a decent set of forged 340 rods. If...

The closer to 100% equal weight, the better off you are. It's that simple. Weight matching by playing mix-n-match is free, so why not?

I would agree with you, but the cost estimate to have my rods resized, reconditioned and fitted for ARP hardware was $20.00 less than new Eagle rods.

Right. Plus, that car was a Mr. Norm's and had 12.5:1 TRW's in it when I got it. No telling if they changed out the crank at that point, but not likely, as they would have had to swap damper, timing cover and radiator at the same time.

I don't recall. That car was totaled almost 50 years ago. IIRC I'm thinking it was a late '72 model.

My original 340 Duster was a 3 speed manual '72. It came with a cast crank. Could the forged cranks have been restricted to 4-speed only and not all manual trans?

Actually, surface rust should wipe off with an oily rag. These things are forged and quite strong.

One thing you can do before you deliver your parts to be balanced; weigh all 8 pistons and mark them with indelible marker on the crown. Do the same with the rods. Try to average them out to the closest mean weight and number the pistons (with marker) to match the rod numbers.

That's what they make Scotch Brite for, John...

I HIGHLY recommend pricing out new forged rods before you send out for balancing. If you choose to use new ARP bolts you will have to have the rod and cap bolt bores bored oversize. That and reconditioning the rods is gonna put you a stone's throw from the cost of new rods. The thought of using...

Additionally, you haven't said said whether this is a forged or cast crank 340 (internal or external balance). As was mentioned, if a cast crank, you need to send your damper and flywheel or flex plate with the recip assembly for balancing.

WRT balancing...you are starting with a completely different set of pistons that weigh more than the stockers. Whether or not you replace the rods as well, either way I would recommend a balance of the recip assembly. You might get away without doing it, but why go through all the BS of...

Just went through this. Ordered Speed Pro 10:1 L2316F forged pistons and found weight to be 727g. Eagle rods are almost 100g less than stockers. And you can buy a set of SIR6123CB forged rods for around what it will cost to refurbish yours and replace the bolts with new ARP bolts.

Ask and you shall receive!

Yeah...you got me. I confess to polishing them.

They're on...what am I missing?

L-2322?

Here is what they look like out of the box...

Yup. With a milled dome

They switched to cast cranks with external balance on the 340 mid-1972. I know because mine was.
