Thx :D

I didnt build my engine as it was sitting in the car when i bought it but here are the specs i know!

Original 340 block 0.030 bored
Heads are MP alu heads converted to open chamber by Hughes
MP M1 intake
Holley 750

MP 4" cast crank that has been cryod
Original shot peened and polished rods
KB Pistons ,Hughes Engines part # 2020+070 , 26.5 cc's
Piston rings are Hughes Engines part # 2114

Duration @.50 239 intake.
Duration @50 242exhaust.

I got it dynoed on rolling highway two days ago and got 300 back wheel hp, the conditions in the hall were it was tested wasnt perfect! It was somwhere around 40 degrees C in the test hall. But now the engine has been tuned and runs like a beast at high rpms so im happy
