1973 454, 60-over
Comp XE262H, 218/224 duration with 110 LSA
049 heads
Edelbrock performer intake
Mallory HEI (which I hate... very unstable spark timing and shaft flex)
2" hooker headers, 3.5" collector, 2.5" duals, Flowmaster 70-series mufflers, H pipe. A litte on the big side but they were new and free.
Qjet 800, carefully tuned with gas analyzer

Part of what makes this a snappy throttle is that with the low compression and auto tranny I was able to lock the mechanical at 36* and run ported vacuum. Its no screamer, but it probably makes a pretty solid 400 hp and it will break loose 255/70-15 balloony tires on a 2.73:1 12-bolt.
