Chevy 400 Build

[khan0165]

you ordered standard bearings? http://www.jegs.com/i/JEGS-Performance- ... Id=1216661

What's the +0.0X" clearance on them I wonder. When you order a replacement crank, does it come to standard size? Or do you need to measure it before ordering bearings?

... trying to learn this stuff

Seems like this block is a 4 bolt main

. Seems like or is if you cant tell the difference you should rethink even trying to build one. Thats almost like saying its a 400 but only has 6 cyl. You better do some research before getting in over your head.

I'm pretty sure the 400 could be identified whether or not it was a 4 bolt main just by looking to see if it has 3 freeze plugs per side vs the standard 2 freeze plugs.

If it is the engine in the picture on page one it shows 4 bolt main caps but appears the inner bolts arent there.

Ive done my research Im just in the process of getting all my parts together. I know the block is a 4 bolt main. Im actually missing the main cap bolts that make it a 4 bolt main so Im going to go with main studs..any suggestions?

Do these engines use timing chain tenisoners????

 

[CHRIS.O]

No they dont use a tensioner. If you want to go studs then just thumb through the ARP catalog and pick a set out.

X2 I always use ARP studs throughout just remember if you are going to use a windage tray to get the studs with the standoffs to mount it.

 

[LilSpann601]

Am I required to use a windage tray? I didn't even know they existed til I googled it. Im still trying to decide whether to use ARP Studs or Bolts? Whats the pro and cons of using them

 

[CHRIS.O]

In my personal opinion for your application, either will work fine. I would go with whatever is cheapest. As long as your using quality, ARP, or GM. I am sure there are other brands but ARP always gets my dollar. No you don't need a windage tray unless you desire one. Again for your application I wouldn't worry about it.
