They are the best flowing 2 valve cylinder heads because... the valve lay out allows the biggest valves possible for a given bore. straightest intake/exhaust ports also because of... central spark plug location less prone to detonation due to the tumble eff. of the valve layout.
that all depends on the engine in it, the 440 magnum and the hemi were pretty fast in the day.
real fast
well the 426 hemi has 425 horsepower stock and also the 6.1 hemi has 425 and the 5.7 hemi has about 380 horse power it can run the quarter mile around high 13.00 seconds in a dodge ram mabye 15.00 because of the weight of the truck
all depended on if it had the hemi engine or the 440 and the rear gearing, both engines were fast for the day.
It depends on the year... 1970 hemi challenger- low 13s @105mph 5.7 hemi challenger [mailto:-13.6@105 -13.6@105] srt8 6.1 [mailto:challenger-13.1@108 challenger-13.1@108] srt8 6.4 challenger- mid 12s@ 115mph.
It will run a high 13 second quarter mile with the hemi engine.
