how to identfy a 371 from a 394
Hi, this is a little bit before my time, my nephew has a 1959 oldsmobile 88 4 door he says it has a 371 in it, i did some research looks like they ran those 2 motors together from 1959 to 1960 and the j2 with 3x2 from 1957-58 i looked on line and found the gold motor and the blue motor, which one is which, they both look the same and i always thought the gold motor were the 394 golden rocket in the super 88 and 98 eights ?? i saw on youtube jay leno has a 1959 88 it has the 394 4 bbl in it and the motor was blue, so what gives, how can i tell what motor he has, he thinks its the 371 ?? thanks for any information !! john !!

Which 88 does your nephew have?
The '59 Dynamic 88 came only with the 371. It was available in two versions, a 270 hp version with the "Econ-o-way" carburetor and a 300 hp version with the Quadri-Jet carburetor. The Super 88 and 98 were available only with the 394 with the Quadri-Jet, 315 hp.

57 and 58 371's have only two valve cover bolts on the center of the covers the others have 5 on the edge of the cover like a SBC..As I remember 59-61 371 were considered small bore 394's and had more of their characteristic (internal parts) than the earlier first generation Old's motors.... Tedd..... Here is a link from the HAMB that will fill you in on most anything about first generation Oldsmobiles..... http://www.jalopyjournal.com/forum/t.../#post-1661960
