And see the &quot;rest&quot; of this car along with some equally impressive cars in the much expanded MASCAR display at MCACN this year!

Agree -- much difference between &quot;select-fit&quot; and a &quot;blue printed&quot; engine ... TAZ

Block decking/cyl head milling. chamber equalized, correct cam lift and rocker ratio verified, oil control, degree cam, carb tricks,etc
Results are nice and not out of line of what should be normal numbers for a non factory,assembly line type rebuild
Even with all this , shows what these dinosaurs need to even try and make 1 hp per cubic inch

to add to the value of blueprinting, there is a nice booklet that bill thomas did on taking apart the 65 L78 for a vette, and redid it to ideal specs and got 500HP out of it (vs the 425 spec).

75HP gain just by getting everything perfect. A little more than a 15% gain.
