The engine is out-------------

The 273 is on the floor finally. I am thinking after talking with the machinest of using a 1970 318 builder block with the 273 heads and solid isky e5 cam at about 9 1/2 compression, decked & heads straightned. I am going with a 2800/3000 stall converter, built 904 with 8 1/4 3:21 locker rear and 15" rear rubber. Eddy performer intake and Holly 4V carb. Stock ignition with Pertronix conversion. Looking for input RE holes in my build. Don't be bashful, if there is a problem, I count on you guys to point it out!!!!!
