This year I am building a 572 CID engine with B1 original heads.
I hope to have it in my 1993 Daytona in the fall, after all points races and the Summit Bracket Team Finals are done.
Basic engine plan is as follows:
4.500” bore x 4.500” stroke, 14.3 CR Approximately 14.7 CR (final CR will be after measuring piston to deck during assembly)
B1 original heads flow 425 cfm intake, 310 exh at 0.700” and 429 cfm intake, 326 exh at 0.800”
Cam duration 282/295 at 0.050”, 0.800” lift, 113 LSA (I have this, but may change)
I need to build headers, planning 2.25” tubes, 4” collectors
I need to buy pistons

Here is my plan for posting progress:
