I had a 318 with KB 167 pistons and SCAT rods and with the weight they removed to balance it the thing reved up real nice and quick even though it had a stock 273 2bbl solid cam. 904 LU trans I had an LD4b intake TTI headers 302 heads and it had 165 lbs cranking preasure and would get darned near 30 MPG on the highway I got right at 29 several times. It pulled real hard right up to 5000 rpm in third even with the 2.76 gears in my cuda. Lots of TQ down low.
