ok. this is kind of dumb but the carb on my car looks bad. its a 1406 and it looks bad. performs good for what it is. i ended up taking the choke off because of having a lot of problems with it. i wanna put another choke back on it but was looking at either a 650 endurashine edelbrock or a 650 vac secondary holley part number 80783C on summit. i figured a double pumper may not work as good for my car but let me know what you all think.



car info. 1969 nova with a 385 stroker eagle rotating assy. with 9.8:1 compression. rhs vortec style heads that are ported. edelbrock rpm air gap manifold. dui distributor. 1 5/8 headers and 2.5 inch exhaust. the cam is a comp cams part number:12-239-3. the specs are:

How bout a 670 or 770 holley street avenger, they work great out of the box, my friend bought a 870 avenger for his 472 HEMI 69' GTX that would not work good with a 850dp but the 870 worked awsome with no problems or tuning.
