I am only 20 years old have already bought the wrong rearend and Cam. This car was my greatgrandmothers Body and Interior are in Great shape Trying to WAKE UP THE OLD GIRL I'M not as knowledgeable as you guys
Thanks in advance

 

Wrong pistons, wrong cam imo, sorry. It'll probably ping even on premium pump gas, unless you're a few thousand feet above sea level.

 

A 650 Holley with vacuum secondaries would be a pretty good match for this setup if you get your compression down.

 

I use an 80457 Holley on a very similar engine works good.

 

jag,

Is that 80457 Holley a bolt on for a stock 350 Olds engine? Need to replace my old tired carb.

 

No it fits and aftermarket manifold.
