The KB 400 is a dome top i told you this in the first post earlier .
I slapped together my dads 383 with the kb 400 edelbrock heads ,rpm intake ,comp cams 275 hl .525 cam and the cheapest headman headers summit sells . The car is a 68 charger with 727 trans and 3000 stall from PTC with 3:55 sure grip . I put a out of the box Holley 750 hp vacuum secondary , never tuned anything except the normal carb and timing adjustments .
I think i built the engine under 3 grand and the performace is awesome the car is a fun street car with unbelievable top end power .
IF you build it like this you will be happy ! you will be able to burn the tires with out brake tourqeing at will .
I would not buy the 162 pistion unless you want to take alot off the deck and heads . to get 9.0 to one compression !
the kb 400 will easy get 10to1 .
