What stroke is that crank?

 

3.48

 

I call bullshit atleast a 3.75 by the look of the crank

 

If you were going turbo maybe but I'll call BS. LOL Well I just bought a used Fast DFI setup that has data logging, wideband etc... for $850 so now going to need a crank trigger and some sort of distributor b/c I am taking off my timing cover and welding an aluminum plug where the opti used to go. LOL

 

lol Its a 3.75 4340 Cola crank.
Fast huh?? Ive been thinking about going that route too. How high you planning to spin that motor?

 

I would like to turn 7400-7500rpms going thru the traps on n2o. well see. later
