Way back in the late '90s we changed our jr/fuel set-up over to nitro in order to run
NE-1 at the West coast events. Our combination was:
406 ci small block Chevy, 10.5:1 compression, iron heads that flowed 306 cfm @ .700,
PG150-1 pump with Hilborn 30A nozzles. Barrel valve @ 28 %. Car was a Hollander/Brown FED 190" wb that
weighed 1475 on the starting line. 4.10 rear & Goodyear 12-30X15 tires. Powerglide had 1.76 low gear.
Conditions were good at the March Meet in 1999. Density alt.at first pass was 1074 ft. Mixture was 35% nitro, .092 main, high speed at 70 psi and ignition at 40°.
Result was 1.12 60', 4.76 1/8th. 7.46 @ 179.78 1/4 mile.
NE-1 index was 7.50 at that time so we backed off to 30%, qualified @ 7.52 and
Managed to win the race on a double breakout 7.49 to 7.46 final.
This combo was very durable and won a lot for us. No bearing problems or breakage.
Fuel set-up credit goes to Gene Adams and Jim Archer. Hope this helps.
PS...Jim Scott now owns this car and still runs it out West.
