RFD CnC 11* Big Chief

RFD has taken a special Dart Big Chief casting and built
the RFD / Top 11 Degree - pro stock - truck pull.

This is a maximum effort big block head for 4.84" bore space.

The head has many features based on our years of pro stock
cylinder head development. Port and chamber design are based
on everything we learned during extensive dry and wet flow testing
on this style head.

It features 11x6 intake valve angles closely matching those used in
NHRA pro stock, and producing very efficient flow, chamber wet flow
and good high lift flow.

The chamber is a very efficient design but is also nitrous friendly
at 76cc. 15:1 with a flat top can easily be achieved in a 632"
or the heads can be milled down to a mid 50cc chamber for N/A
small inch comp style engines.

Several port sizes and valve size combinations are available, ..
2.4" intake to 2.52" and port sizes for 521" up to 632"+
1500 + hp capable - flow as high as 570 cfm depending on application.

Simply the best CnC machine work available to the public, ..

Starting at $5250 bare , custom built for your application
