Barry_R Barry in some cases, it's all about the application and useage of the motor. I have an iron block in my shed. It's a 390 block with 428 crank. For street driving I may have stayed withthat setup. I wanted to use my car for autocross and roadracing. Iron was not the answer for this. I want a lite car. Aluminum every where I could. Heads, Intake, Block, timing cover, valve covers, even the spacer on the crank. With your kit I came in at 508 pounds. Over 600ft of torque and 540 HP at the crank. Small block weight and good power. You know how hard it is to find an old FE core for building. I am gald Mike Lefevers got CS to build their heads and blocks. Over heating with aluminum was an issue but now is fixed. 8 years on the 452 motor now 3 with the 482 kit. this is with the same block. Alot of abuse and some upgrades in the block from helicoils to timecerts in all the holes. Given the flexability of aluminum or iron and the fact you can repair it alot easier, I like it for racing.
Iron for a street car or 1/4 car with the water jckets fill to the bottom of the water pump holes is better IMO that an aluminum block. Some of this also depends on aluminum or iron heads and intake.
With all this being said, how is the cammer motor going to be run? Can we hope for the 800HP level to get reached? Rick L.
