A budget build up.

This is for the Ranger.

Cast 3.4" Crank
Bushed Pin 5.09 Rods
-2.7 Dish Pistons
World Windsor Jr Iron Heads
Edelbrock RPM Intake and Cam
570 cfm Holley Street Avenger

Should be good for 275HP/310lbft

.040" overbore might be pushing it.

I had a 570 Street Avenger on my 302. It was a very nice street carb and worked OK at the strip with a different accelerator pump setup and a lighter secondary spring.

The 570 avenger is closer to the 450 cfm Holley than a 600 holley as far as throttle size and venturi size goes. Primary jet size is in the mid 50s and secondary is in the low 60s. I found the factory jetting to be about right for my 302. I richened it up a bit, but only 2 jet sizes. I ran a stock 650 double pumper on the car to see what it would do. I ran some passes with the dialed in 570, then unbolted it in the pits and bolted on the 650 double pumper. The double pumper did not need any mods to launch cleanly dumping the clutch at 4500 rpm, whereas the 570 vacuum carb did need tuning at first. I did not pick up with the 650 DP, so I bolted the 570 back on.
