I know Why NITRO is $35 a Gallon

Dave if you need to you could go to a colder plug . I am using 10's in mine and might try an 11

Dave...
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.

Thanks Mike!
I worry that my alky compression ratio of over 13.5 is my limiting factor for sure
I am running an NGK 5671-8 plug they look great--no heat up the threads at all so had not thought about colder plug yet but I need all the help I can get here
Thanks everyone!
I know I need to leave harder for starters I had been foot braking--did install a trans brake but have not tried it yet
Thanks Everyone!!!

How much stall change so far. According to Spuds TQ calculator I should pick up 250 lbs at 30% and that should be 700 to 800 more stall according to FTI. Will probably get second converter for car.One for alky and one for nitro. Present converter is 6600 on alky ,will have to check with nitro mixture.

The hotter plug will nip the ground strap and warn you before you get to aluminum if your lean. 33% is where things change. I can't speak to your compression ratio/cam combo but my BBC @ 12.4 was the same jet/timing with 30% as straight methanol. It started to slow down as I added %. converter becomes more critical.
Welcome to the addiction.
