I have always liked the cycle fenders on some of these cars. If I had more money that organized crime and religion,I'd buy a "J" and restyle it to incorporate these fenders.
What was the CID of these old engines anyway.I don't think any of them were even 300 CID.

Nowhere near 300 cid, more like 260.

Years ago,about 57 of them,a close friend had a pristine 1941 Nash 600
with a straight eight engine and an overdrive transmission.This engine was about 260 CID and had the valves in the head,sixteen spark plugs and nine main bearings and held about ten quarts of oil.I considered it a superior car to the 1937 Cadillac V12,Series 85 sedan I owned at that time.
The Nash was smooth running and with the overdrive engaged could get twenty miles per gallon on the road. Not bad for a car some considered as inferior.

Hello Bob,

like Mike said before the CID would be 260 cui.

If I remember it right, the engine has a two valve, (single) overhead-camshaft-head with spherical combusting chambers. The camshaft is driven by a vertical driveshaft (with bevel gears) a so called "K?nigswelle".
Single updraft carb (1.5' ?), three main bearing crankshaft, compression ratio 5:1 and the power output was rated at 88 hp at 3600 rpm. (source: automobile quarterly Vol 30. No. 4)

Cheers

Matt

I'm with you Bob,

In my experience, folks who appreciate engineering agree: that dual ignition ohv Nash was one heck of an engine.

Bob Roller replied the topic: fine engines
To me the 9 mainbearings of the Nash were a much better idea than that spindly crank with 3 mains that the early Duesenbergs used. The big 9 main bearing Packards I always thought were a better idea than the 5 mains of the "J".
