Anybody have a gear recommendation for Oskaloosa, IA? Planning to run there with an open motor next week.

Southern Iowa Speedway--semi banked 1/2 mile. we took a open motor a-mod up a couple years ago and ran a 5:14 turning 8000 rpm. Hope others chime in on this because I don't want to put you up a creek without a paddle. Vintage Mod

A shift in the trany might help! We ran a (two quick) in a limited late class once! It was great for starts and tacky heats with only a thousand rpms difference!

Running a racegator(brinn copy) transmission, changing that out at this point is not really an option. We have a 5.29, just a little worried about hitting the 7800 chip too early. Motor is only probably 500 horses though, so that should keep it tamed down.

Lower the timing and up the fuel!

Only have 32 degrees of timing in the motor currently, running on alchohol and had it tuned on a dyno. This is our first time running alchohol so adjusting the fuel is not an option for us at this time.

More oil on the filter or a net or raising float levels or pressures will raise the floats to put more fuel in if needed! Engine temp control is a must! A good thermostat is warranted to control burn temps on alky! Watch the temps on the header tubes, if you get too much fuel in it will turn them red and crack them up quickly! A flame in the tube can suck the engine lean quick! We melted number 8 piston 3 times before raising the timing to cure this problem! 38 on most any 350 stock stroke engine even on gas! 44 on alky is common! You best read number 3 cylinder and number 8 for oily wet threads of the lest 3-4 to the seal and use a good top lube every time! Mix thoroughly before pumping each time from a drum! Be sure to use a filter in your funnel as fuels can be dirty and water loaded, this will stop up the fuel log filters quickly also! O-rings and filters should be kept on hand always! A little gas will crank a flooded engine on alky! If you spin the motor a time or two before pumping the fuel in and then count to ten slowly to give alky time to evaporate to fumes from the heat generated by compression when spun, it should bust off with no gas needed and oil primed! If you touch the throttle first before or while spinning and counting to ten when cold it will not likely crank and you will need gasoline to crank it up! Many have these problems until warmed up! A electric idle solenoid or long flex idle screw adjuster is available to aid in warming your engine as some are quite cold natured as to cam degrees! It took us a while to adjust to the tricks of alky! Hope these helps you transition! One more bit! If your distributor is locked or pinned you lost 30 horses on the dyno! Cranking timing and running timing should be different if looking for horses and if locked, that is the reason for the lower timing unless 13 to one pistons or brake-in option, or long stroked engine! I may use lower timing to de-tune but never pinned! A 6-10 degrees drop works great for cranking and hooking off the corner for a couple of car lengths!
