National Trails this spring. What's going on???

I bought one for my 70 road runner but is presently on my run stand. Went with the unpainted version, very nice quality and best deal I've seen.

Stock press fit rods with Summit Racing forged pistons. Total Seal gas ported rings. https://www.summitracing.com/search/part-type/pistons/make/chrysler/engine-size/6-3l-383/engine-family/mopar-big-block-b?N=rod-length%3A6-358-in%2Bbrand%3Asummit-racing&kr=Pistons&outofstock=true

Put me down for 13.90

Didn't see what cam are you going with?

They are for sure. With cylinder number on early engines, and symbols on the late.

I doubt they'll ever be used. Slow day so going through some junk on the shelves. Other than the file to fit, oversize rings must have an expected end gap I would think?

Stupid question - How can I tell if some NOS piston rings in an unmarked package for a 440 are .030, .040, or .060 oversize? I can place a ring in a 4.350 bore and the gap in almost butted together.

I thought about that too. Wondering what would happen with the smaller floats swapped into the larger primary type carbs?

The carbs are in the 1968 - 1969 range. 4401,4615, 4682 small carbs and 4640, 4618, and 4429 for the larger carbs.

Yes, I think the floats are original, I had several parts carbs to compare. The small primary carbs all had the small smooth floats, while the big primary carbs had the larger "corrugated" type floats. The rebuild kit instructions actually have different float height/drop setting for each type.

Fuel regulator must be mounted at least 6 inches ahead of the firewall.

I recently rebuilt and tested 4 AVS carbs that I had. Does anyone know why the float sizes on the 1-7/16 primary carbs are different from the 1-11/16 carbs?

They only have someone answering the phones a couple of days in the week. Kits are made in house and totally worth the trouble.

Yes, you have to call them, all of the kits aren't listed........and the phone is answered only a few days of the week (I got through on a Thursday). I bought a kit for a Carter 6903, which late versions are notorious for putting out too much pressure for an AVS/AFB carb. Their kit worked...
