Re: 355 cu in and 700r4

Slow-1,

Any chance you know what mpg you are getting with that combo? I have the same set but in a 69 step and was thinking of going to an overdrive.

Thanks,
Jim

Re: 355 cu in and 700r4

Just removed the metering rods and found there is no spring for the driver side rod. Also the 2 rods are different sizes. This was suppose to be a new carb.

Re: 355 cu in and 700r4

I bought the whole engine in pieces from a guy. Every thing was new or rebuilt and I had to put it together. I would have never thought that a spring was causing all these problems. Are both metering rods suppose to be the same size? Thanks for all the help.

Re: 355 cu in and 700r4

I have no experience with Edelbrock carbs.

I would start a new thread about it to see if you can get someone who knows them to help you.

Yes, both should be the same.

Smile Re: 355 cu in and 700r4

What tire size are you running?
...noting that the bigger the tire the worse this situation becomes.

Re: 355 cu in and 700r4

I am running stock tires. I think the whole problem is the metering rods and springs. Ordered the set today so now can't wait for them to get here.

Re: 355 cu in and 700r4

I have not checked it since my last engine rebuild but was getting 17 to 18 the last time I checked...which was probably right after I put in the trans 11 years ago.

I drive it a fair amount and seem to need gas at the same intervals as my wife who drives a Honda Pilot (20 gal tank and 17-20 mpg).
