Large Displacement (500 Cubes +/-) Straight-6 gas engine?

[AlbertS]

Just wondering if anybody knows of a 1/24 or 1/25 large-displacement engine around 500 cubic inches that anyone has available or if the resin folks have one coming along eventually?  Am intending to put it into a 50's old school (used to be a tractor trailer truck but is now) semi-retired farm dump truck?  Thanks in advance for your response/guidance.

I'm kinda looking for something similar,  like a GMC 503 I6

Can’t help, but here is a pic of the GMC 426/503 on the left and a GMC 302 on the right. It’s a huge beast!😬

 

And here is a pic of the GMC V-12 in a hotrod. I believe Texas 3d makes both the V6 and V12 version.

Was thinking about a big 6 gas job also for build. The Mack  6 cyl. diesel has similar dimensions of the big 503. Valve cover looks similar to a V8 Detroit Diesel.  Add a distributor cap and spark plug wires, could get close.
