The most expensive one!

Dave , I use the 055 intake on my 1981 malibu, you can`t use the 053 on 80 or 81. Tom

I just looked at the blueprints specs again because I have 053 for mine and got worried I had made a mistake. But it is listed as an alternate manifold for the 305. That's the manifold several really good engine builders told me to use. JMT.

I had the same Question and spent money to find they are virtually identical. That is if the iron one wasn't very heavily rusted. ...Thanx Trevor

Thanks to the guys with helpful responses and the guys who PM'd me.

tj310, do you mean you found the 055 and 053 to be the same performance wise?

Any experience with a 440 vs a 432?

Re: 305 intake manifold question
 

The CAST IRON one that weighs the same as the ALUMINUM one is usually the BEST one.
