Carburetor questions

['73bird]

I have a 1973 stock 440 motorhome home motor. Recently came across a very good deal on a holley 4160 (i believe) (6160-1). Should i use a spacer? If so which one?

If this spacer is to be used in the expectation of performance gains, spend your money elsewhere.

Ok so they are worthless?

There might be a couple of reasons why a spacer could help; a non-metallic spacer often helps the carb run cooler as it acts like a heat insulator. Sometimes the extra height, if you have room for it, can improve top end power. Take a look at this sbc article: http://www.hotrod.com/how-to/engine/0601phr-best-carb-spacers-cheap-horsepower/

Not completely. As Photon440 mentions, they can help if you're having fuel percolation issues. My vapor lock is gone.
Are you looking for a cheap power adder? Headers, 2nd hand intake and a weekend of slipping in a new cam and lifters will wake that baby up.
My good buddy used to run those 440 motorhome engines all the time in his '69 Dart. Fenderwell headers, a cam and intake swap and he'd pretty much be lifting the front wheels. Of course, a few weekends at the track and he'd be doing it all over again but man, was that car fun!

Before going into the roadrunner its going to get a full rebuild. Was just wondering if a spacer would add anything

It's certainly not going to hurt.

I went with a 1/2 inch spacer
