L Series Motor Mounts

[Wizeguy9999]

Hi:

 

I'm building a 68 Datsun 510, and had a question.  The L-series that I'm putting in is well above the 90HP of the original L16.  I was curious if this would require better motor mounts than OEM equivalents.  If so, does anyone know where you can buy beefier L series motor mounts?

 

Thanks for the help!

The stock mounts are fine. They aren't designed for HP rating, but for durability. Newer ones are softer and technically handle less torque, though after market ones are all the same.

Would an increase in weight matter then?  A 1.6 liter versus a 2+ liter engine?

 

Here is what I'm looking at:

What generally concerns me (and maybe it shouldn't, and I should be happy and move on) is that these are so inexpensive versus upgraded motor mounts for installing like a KA (those seem to run like $100+).  It just seems odd that the motor mounts could be basically the same but the cost be so different.

The L16 mounts work fine with a KA24

L16 255 pounds

L18 260 pounds

L20B 275 pounds Taller block, larger full counter weighted crank, longer rods

 

Motor mounts are not an issue.
