Ive been offered one cheap, and just wondering what it is, looks like a double pumper, anyone know what size?
A 6210 would be a 650 cfm spread bore double pumper-small primaries and extra large secondaries. Designed for GM vehicles in the 60's and early 70's. It was calibrated for pollution control and was a suitable replacement for the Quadrajet.

Not particularly valuable--I sold 2 on ebay for about $40US each on eBay.

You would have a hard time using one on a Ford, as very few manifolds have the correct bolt on pattern. I ran a 6210 for many years on my 351w using a Holley Street Dominator. It did well as a daily driver and would knock out 19 MPG on the highway.


65' Stang

393 stroker, Toploader 4 spd, 9" 3:50 rear.

Victor Jr. Knockoff Heads, 282S cam, Stealth Intake, Bigs Stage 5 750DP, Accufab Headers, Scattershield, Caltracs.
