1969 cutlass 350 motor with 68k miles, think the cam went flat or a push rod is bent, dont know, has a loose rocker arm, complete quadrajet carb to pan, has a HEI distributer #5 heads too..text me for pics 714 883 6171 or call me...Im open to offers and want it gone asap....thanks,cameron...

 

Here's a pic of a W31 balancer, two inches thick, much thicker than a regular 350. All 350's had #5 heads whether W31 or low compression, the W31 having the larger valves, 10.5:1 pistons, and high lift cam. The four barrel carb was standard on the Supreme, and optional on the F85 and S, numbers for the carb would be specific to a W31. It could be the 10.25 compression 310 hp motor, so having #5 heads and a four barrel does not make it a W31. Really the only way to know for sure would be to have paperwork from the car from which it was removed.

 

There's no P/N on the backside of the balancer?

 

The std. balancer is no where near 2" thick, so if his is not 2", then it ain't one.

 

Yes, W-31 balancer is just shy of 2" thick and has HT stamped in a square depression on the front and HT-1668 stamped in the recess in back of it.

 

ok its just a 350 motor with #5 heads and a stepped balancer that looks to be 1.100" thick. thanks for clarifying this. so are any of you guys interested in it ? i hate to scrap it!!! thanks-cameron

 

ok, so its just a 350 nothing special, up for sale 150 bucks!....text for pics...thanks,cam
