We have a stock stoke .030 over 400 in my boys Dart with the 383 crank. It has KB pistons and with Eddy RPM heads that we cut it has 10.6 comp. Has the MP .557 cam and a 750 DP. Never dyno'd it but in his 3550 lb Dart it has run 11.40's @ 117. Its pump gas drive anywhere street car. Thats real nice looking 400 you have there. Do you plan to try and dyno the 400 with any other combo's in it ? Ron
