Hey all,
My daughter is looking to build a 400 for her 72 SWB truck; we are looking for some ideas for the motor build,
the 400 is a 72 Steel crank engine out of a 4 sp RR , its going to need to be bored and decked , now she can't stroke it only an over bore .Truck is manual brake and steering, and a 4speed
She's looking for something on the edge of street ability single 4 bb.
Any ideas on heads (906,452,516)

she got herself into a bet with a guy who has a 396/402 BB chevy C10 swb truck and they're going to race each other at In June to see who's quicker, both trucks have to be able to travel 35 miles to island dragway
Both have agrees not to spend more then 5k, and each must use period corect block and heads.
all Ideas are welcome
