Nice setup I ran before the twins. Thumper Performance ported E7 heads as seen here http://www.thumperoforangepark.com/ ported to flow numbers shown below shaved for higher compression (10.3:1 on stock 5.0 with no intake mods needed)!
B303 ford racing hyd roller camshaft. I never had the car dyno'd on this setup but I ran pump gas on 16 degrees base timing with an aod for years and can say It was a high 12 low 13 car that had the nicest sounding idle I've ever heard and perfect street manners. Made awesome power.
Heads are in machine shop as we speak getting a fresh valve job and a cleaning/paintjob. Will have fresh valves and seats upon delivery.
Two thumbs up on this for anyone looking for an impressive performance increase for relatively inexpensive. $500
