Olaf......
When you use any of the Keith Black pistons for the FE's you have to narrow the pin end of your rods to accomodate the chevy 1" width.....and I was not aware that KB offered a 427 bore piston at+.007 +.010 = 4.250" for a 428 3.980 stroke crankshaft.....you better check that one a bit closer or perhaps he's using a 454 piston for your application?...perhaps an exact Arias piston would be better suited, there forged and the same price.....

The rings seem about 50$ to high, Lifters seem in the ball park as do the valves if they are Ferrea or equal....
why do your Dove Rollers need new Shafts?
This price seems very cheap to me....I'd be check ing all the operations he's offering verfy carefully...
Just some thoughts...
I agree with the comments about the roller cam.....but I run one on the street....and yes at 4-5K miles start expecting some replacement parts on the roller lifters etc...
