So today I’ve been doing some bench racing while working on the old 37 Hudson. Along those lines I’m wondering just how much carburetion my little 212ci engine can’t handle. I found it interesting that the terraplane had a one barrel carb while my six has a two barrel carb & to me that spears to be a doubling of carburetion with no other changes to the engine. So my “bench racing” question is how much more carburetion can this 212ci engine handle?
To help this discussion here are the basics of my 212ci engine is standard bore. With the engine refresh last year I honed cylinders with new rings on stock pistons, new 1938 & later valves (for their smaller stem diameter) with matching cutback valve guides and a complete porting of the engine with gasket matching to help airflow. However intake & exhaust valve head size are both still 1.375“ & the compression is around 8.5:1. Everything else is stock.
Sitting on my shelf is a straight 8 carb WGD & measuring the bottom of each barrel I find 1.3” vs my stock carb at 1”. Now it’s not a direct bolt up since the bolt pattern is larger but perhaps someone has already done this & has made an adapter?
