Quote: i think a 604 w/B1s would make a good street engine..i would use a purple shaft cam and have the best of both worlds...
Step up to the 650 Comp flat tappet and I bet you would have a winner My uneducated , untried recipe; 604 with B1 heads, Comp 650 cam, Titanium intake valves in 2.3 diameter, 1.6 rockers, tunnelram with twin 750 carbs. 2 1/8 headers 35 inch long, 4 inch collecters. Use a small combustion chamber with a big dish piston for 11/1 compression?
