Thank you everyone. I will not use a lockwasher and the engine will be broke-in inside of the car. I have thought about snugging it now while on the stand and then finishing the torque once I have it in the car. But I am afraid that I will forget. I like the note on the windshield idea! I...

I want to install my harmonic balancer this weekend on my 340/420. I have the balancer installation tool and I have torqued the balancer bolt with the engine in the car a handful of times. I made a bracket that bolts to the balancer, and rests against the k-frame to keep the crank pulley from...

I use this ProGear set mentioned above (Hughes Link). https://hughesengines.com/Index/products.php?browse=category&level0=QS0gU21hbGwgQmxvY2sgIkxBIg==&level1=VGltaW5nIENoYWluICYgQ29tcG9uZW50&partid=23311

Anyone running into issues with valve spring delivery dates? I ordered a set of Manley springs/retainers/locators 5 weeks ago and the retainers/locators delivered in 3 days. I am now approaching week 6 for the valve spring back order and still have another 4 weeks to go. I have 4 other valve...

I am using aluminum heads and water pump. The heater core and the radiator are the stock type replacements. Thank you everyone.

I am thinking ahead of what type of coolant to run once I get my 340/420 back in the car this Spring. The engine was completely cleaned, and my radiator and intake were cleaned out too and sitting dry. I will be using new radiator hoses, and then the only other pieces are the heater core/hoses...

Cometic makes a #C-5457-036 (4.125" bore x .036 thick) for a reference.

Do you guys worry about the temperature in your garage/shop etc., when applying the sealant? This time of the year in my garage, it can be 50 or 30 degrees. I need to get my water pump housing/water pump/oil pan sealed up in the upcoming weeks and I have wondered if the temp will affect the...

I finally got around to degreeing the cam today. (109 installed at 105 per cam card) I first chose the 3A option and it came in as 102.5. Then I chose the 2A and it came in at 106. I’m good with that. Thanks everyone

For discussion, this is the X-celerator with the Mr Gasket 5840 gaskets. There is a lot of meat left in this intake.

Thanks for the confirmation! This definitely moves the 360-3R off the table for me.

If that is true, I was not aware of that detail. Thank you Michael!

I agree that it is a mismatch combo, but I am going to work on that over the next year or so. This is a numbers matching 340 car that I have had for 23 years. I lost the crank about two years ago and I am just now getting it back together. The heads are ported Sidewinders (280cfm @ .550”). I...

I have started assembling my 340/420 and I need to start deciding on which intake to run. I currently have the following two intakes: Non-Airgap RPM Weiand X-celerator (small single plane) I have gasket matched both of these to the same intake gaskets, and the depth of the match is about the...

""the longer the stroke the more displacement BUT also the increased risk of interference on the assembly."" My 340 now has 4.00" stroke and a 4.090" bore. The crank and rods are from K1, and my machine shop had to clearance around the rod bolts (ARP 2000-10) which can be seen in the attached...
