 *Stock converter and stock rear gear will work, but would be more fun with a converter that stalls at 2000 to 2200 rpm's and a 3.73 gear. The most out-of-whack spec on this build is the fact that RHS flows their heads on a 4.200" pipe. The resulting flow numbers bear little resemblance to real-life flow on a 4.030" cylinder bore. If you want closer to real, multiply these hp/torque figures by 0.95.
+*383 Gen I street motor.
+*OK, staying with the RHS heads, but using the Pro Action 180's and reducing the advertised flow by 5% to get closer to real, flow used for this build on a 383 will be as follows:
+*.100 70 55
+*.200 143 96
+*.300 197 149
+*.400 231 168
+*.500 245 177
+*.600 250 181
+*.700 257 185
+*We'll bore a 350 block +0.030" and use a 3.750" stroke crank and 5.7" rods. Scat makes a cast STEEL crank and capscrew I-beam rods that will work here. If you want to use a 4.040" bore or 4.060" bore, that's OK too.
+*Heads: Racing Head Service Pro Action 180, 72cc chambers, 2.02" intake, 1.60" exhaust.
+*Pistons: Keith Black hypereutectic #KB134, 7cc flat-top, 5/64/5/64/3/16 rings, 1.433 compression height.
