Stock stroke 360 with Eddy heads (60779)

Easy to make 400 HP with those heads unmodified. Life is so much easier than when such heads did not even exist...... Just read the threads on having them checked by a machinist and not assuming they are perfectly made. We are expecting 375-400 HP from our 340 with a 268 advertised duration cam with 1.6 rockers at around .500" lift and decent intake, headers, and 670 cfm carb. Plenty for a light '65 'Cuda for some fun!
