Best 273 and 318 builds (NO 360's please)

bottom end is stock cast crank with 360 floating rods on KB forged .040 over 1.81 CH pistons and chrome moly ring set. Block is squared & decked with the pistons .002 in the hole. Cam is a comp XE268H flat tappet on 1.5 stock rockers. Indy/RHS 62 cc quench heads from Hughes with no port work done but .192/.162 valves with multi angle grind and a .042 head gasket. On top is an eddy air gap with an eddy 600 cfm performer and pertronix ignitor II ignition.

I figure between 9.5 and 10 to 1 comp?? should be at least 350 hp with comparable torque?? I don't know...
The engine is assembled, installed and after addressing the extended accessory mount bolt hole boss issues in the heads for alternator mounts it should be ready to fire this monday...tomorrow Yippee... What kind of numbers do you guys think this combo should put up for hp/torque and 1/4 mile times in a 68 Barracuda 904 with an 8.75 and 3.23 suregrip on BFG 255/60/15's?

I cant wait to see this baby run....
