463 Tx2 performance
The 463 (Tx2) machined by Brian Maloof in GA was run for seven years, and over 1000 passes were made with it. This engine initially had #62 D-ports and did get into the tens with these heads at VMP. Next came a set of SD ported E-heads, and picked up about .5 when I made the head swap alone, and it ran a best of 10.36 with a Q-jet at Carolina Dragway SC. I eventually swapped to a Holley 850 DP to run E -85.
