My 69 Z28 was in the shop getting paint.Had to be left alone for too long.Between the tow truck driver and the vinyl top guy somehow I dont have a DZ carb anymore.I'm now the proud owner of a 650 Holley double pump.My question is this....I have pulled it off and placed it in a shop to be rebuilt.The original DZ carbs were 850 cfm were they not?Will this 650 cfm work with my 302?Should I bite the bullet and get another DZ 850?Very frustrating to say the least.I did an intro a long time ago but forgot my password.Thanks in advance guys!

*Edit* Just realized this is kinda a loaded question.The z would run with the 650 on there but it would cut out at high rpm's.Like right before you would shift.Also it loaded the engine with fuel(oil pan and all)so I pulled it to rebuild.This is when I realized it wasnt the DZ holley.Also this was only within 100 miles of getting it back from the vinyl shop.So,just wondering how the carb would do performance wise I guess.

 

Actually, the original Z28 302 carbs were 780 cfm with vacuum secondaries. The 650 double pumper should perform very close if it is jetted properly, since it will actually flow a little more than 650 cfm.

 

Right on,thanks for the info!I was curious if the 650 would do the job(answered) and what the main jet should be as well?
