David Vizard bench flows a BBD 2bbl

In my opinion of using aftermarket parts on this build is limit it to what is cost of new verses referb'ing old junk.

Take the 318 con rod. How much cost to totally referb it and grind it lighter or just buy a set of Eagle H or I beams that are a bit longer to get to "O" deck with a stock or maby a 0.030" over piston? Then rebalance the stock crank after knife edging the counter weights and coating it. I'd bet they can take 4-5 pounds out of that cast crank.

Yes using Eagle rods will require new pistons with pin locks as the 'Teen' is not full floating. Could get the Eagle rod bushed for press fit but why, just get some newer pistons.

Use a good DEEP and baffeled oil pan with a scraper and power buldge. Oil pump with a direct cover drilled inlet of 5/8". Drill all oil passages MAX size.
