What mounts to use for K20 BBC install?
I am looking for information on what mounts to use for a 402 BBC install into a 72 K20. Right now the truck has the original crossmember and mounts for an SBC 350 motor.
Was wondering if there is a new version that will work or possibly a tubular weld in set. Thanks for the help! |

I have done numerous BBC conversions on 4X4's and always just used the small block mounts, I will add that you may want to move the entire setup forward approx 2-3 inches as if you are not using a body lift the valve covers and distributor will hit the firewall, especially if using an HEI distributor, Here is a pic of a BBC in a Burb using the stock small block mounts and location, as you can see its a tight fit, the other picture you can see the previous owners modifications to the fire wall to make it work, even so the distributor was almost touching.

Re: What mounts to use for K20 BBC install?
My 68 is an original 396 pickup, and YES, it came with that engine, and I still have it...I bought the original type (68-71) new mounts, years ago, even though it has not had the engine in it, for waay too long.
I found out about the 72 clam shell style mounts (that are like the 73-87 mounts (small and big block). My hop is to use the 72 clam shell mounts in my big block 68 AND I and putting a small block in my 67 C-10, plan on using clam shell (72) on it too. THe design looks better for the long run...to me. I have a 73-up setup (frame brackets and clamshells, and engine brackets) that I may experimnt with on the 67... Oh, Landarts! Thanks for your builds, here. There are great to follow, and helpful in all aspects of your repairs, especially the body work! I hope you are recovered from your health issues, so you can do MORE work, and post here!!! My interests are in 2WD stuff, but your 4WD and 2 WD stuff is ALL good!!! |

I have a extra set of the bbc motor mounts that are for 1972 on up trucks, I don’t have the clam shells that bolt to engine but them are easily to purchase.
