Someone keeps trying to make this a top alcohol Dragster post from 25 years ago but most of the bracket style engines out there are under 12.5 compression. Matt’s engine and mine are around 11.5


The carb engines are very popular and can be set up to run a lot cleaner than the toilet engines. Matt had a 750 on his engine and sold it wanting to update to a Billet carb. He has his friends 900 on it now and they both ran 6.54 on his stock crank 360@3200 pounds. My 422 has gone 6.001 in the 1/8 and 9.42 in the 1/4@2860 pounds with an 850 carb. When and if I go to a roller cam I too may step up to a bigger carb.


So simple answer you don’t need a high compression engine and the alcohol carbs run super clean if you use the tools available to set them up right.
