Is that particular hybrid block (3L bored and stroked to 3.5) susceptible to detrimental thermal expansion?

oh, and to answer why, HP



Listen to Demon, you DO NOT want to run FI on a 3.5L, instead take the cost of the 3.5L conversion run a 3L with a turbo with upgraded guts and enjoy 500-600 hp. That 3.5L is going to be HELLA expensive and a time bomb IMO.
