Flow numbers for Edelbrock Hemi heads - 05/23/14 04:29 PM

Int 100-86 200-168 300-238 400-313 500-375 600-398 They actually stall above that .
Exh 100-70 200-140 300-188 400-223 500-242 600-249
These were tested OOTB with zero prep of any kind on a historically conservative bench. Tune up the valve job a little and smooth out s few wrinkles and 425 to 430 and 290 to 300 look to be pretty easily achieved without heroic measures.
Just thought y'all might like to know....Todd

They were tested here in North Carolina. Yes they use all stock type parts Except the intake valve which is 2.32.I have not seen any numbers from Edelbrock except HP numbers from dyno tests.

If I read the Edelbrock ads correctly the exh valve angle has been moved.It would follow the exh valve notch in the piston will need recutting to match.They do claim they are bolt on using the stock valve gear,covers,etc.
