I am Chevy guy for the last 20 years and completey new to the Mopar scene so i need some advice.I am building a 440 for street strip use with a 6- pack. I need to know what factory heads flow well or a couple good choices of factory heads to use on such an engine.Basiclly need some good torque and i will not spin it any faster than necessary,just need a good streetfighter! I realize the 6 pack will kill it on the bottom end so i will use a small stall and not a huge came. Thank in advance

the Alum Edelbrocks are hard to beat out of the box..you will spend more money messing with a set of steel heads unless you run across a set all done on the cheap...Bobby will know a good # to look for... I cant recall the head number for a decent steel head..for some reason 660 or is 996??? is coming up from the memory bank but I am sure thats not right...I hade a pumped 440 out of a 70's drag boat around here.. I cant find my notes on the numbers I had this morning.

The old head is a 996. The 6 Pack wont kill any bottom end. Actually they work great on the street, as the center 2 barrel does the major work until the vacuum tertiaries cut in (I've been waiting years to use that term: 'cuz a 6 pack doesnt have secondaries)

I dont see any 996 numbers in my application book,what would they have come stock on? I do see they used a 906 from 68-70 could that be it? Thanks

906 is the number for the HP heads. I would go with the Edelbrocks, they are worth about 40hp over stock heads right out of the box, disapate heat quicker and are lighter. You can paint them and grind off the name so they look close to stock.
A dailed-in 6 pac for the street is the way to go! |
