What stroke ,rod and bore is the best comb for a blower motor? I have a 8.2 dart block with 3.25 crank now just wondering what is the best way to go. Thanks for any info on this. Jeff

So a 3.4 crank and a 5.4 rod and 4.185 bore is the best way to get to 363? Sorry im still learning. I saw a few 3.45 cranks for sale and was not sure what works and what doesn't. I guess its best to keep the stoke shorter for better side load on the piston. Thanks for info. Jeff
