Hey Chris,
I built my entire motor myself, from top to bottom. It should be above 425 HP. 347 Stroker w/ Alluminum Heads w/ 10:1 compression, Z-303 Cam, Hypertecnic Pistons, Roller Rockers, Roller lifters, Edelbrock intake and Carb. I'd like to get some more information on your motor to see how close they are built and also let me know how it did onthe Dino.
Thanks,
Phil
