For our 318-specific HMC1326AL-9 Musclecar version, this is done with a 109º lop separation using a lower intake number (.517) and higher exhaust (.552); duration is also split at 213º intake, 226º exhaust. Here’s what it does – by making the smaller size exhaust valve more effective through additional lift and duration, the Whiplash scavenges the cylinder more effectively. This thing is made to work in the 2000-6000 rpm range; it’s not for a Super Stock car, and other than an occasional trip down Bristol Dragway, its biggest acceleration sites will be highway onramps and places where 1-2 is the most shifting we’ll do. The lope will be impressive; the increased performance will exceed that.
Part of the reason the lift number is so high is because Hughes also offers a 1.65 ratio rocker arm; had we stayed with the standard 1.5 ratio, lift would have been .485 and .518, respectively, which is still fairly stout on a street motor, but our larger ports will make use of the extra airflow possibilities. Hughes offers rockers in both ratios; these rockers are beautifully made from an aluminum alloy. Moreover, since the AAEQ heads use the pedestal mount Magnum rocker hardware, as opposed to the old shaft-mounted versions from the old days, putting these rockers on was a no-brainer. The AAEQ heads also take the Magnum 10-bolt covers, something that has been a problem as the national ‘clunker bombing of 2009’ took a HUGE number of these cars and Magnum engines out of commission; our friends at Mopar had a set of cast ones that will be the perfect finish.
When we were at Hughes, Dave and his crew showed us around. They have been doing this for a long time, and there were customer engines awaiting completion, heads getting reworked on their CNC machine, and a busy customer service desk. Like a lot of small companies that know what they are doing, Dave and his crew find there are never enough hours in the day. Take a look at our cam outfit, and take an exclusive tour at the Mopar-specific Hughes Engines shop, ‘where you always get "REAL"™ Mopar Parts.’
