Title: A and B stroke piston weights and other questions Post by: RFbuilt on June 19, 2011, 11:01:09 am greetings guys,
ive been wondering, lets say on a "inbetween" stroke , (i say that cuz the bigger stroke sometimes are easier to configure) 74-76mm stroke these strokes can be used with 5.4" stock length rods , with a decent amount of barrel spacers and we all know alot of engines like this have been built , using A pin height pistons ofcourse i wonder though given the same stroke , using a 5.5" rod length would be possible with a B stroke piston height example lets say a 74mm stroke + 5.5" rod length, maybe would need 1mm to 1.5mm of turning on the barrels to give use decent deckheight in the region of 0.040-0.050" depending on case height the question is (for me atleast) does the benefit of B stroke pistons (lighter since theyre shorter) outweigh the hassle of running longer rods and or turning barrels ? i know eliminating the barrel spacers, and making the motor a lil less narrow is a benefit but im wondering strictly on piston benefit alone is it something we could notice in performance/drivability , the weight difference of the piston + the added weight of the 5.5 rod vs 5.4 im imagining on a high rpm highly tuned engine.. it might be beneficial , longer rods, wrist pin closer to the top of the piston for less "rock" at tdc and bdc , but how bout for a hot street engine? if this is such a useless question pls dont shoot me its my 5th cup of coffee already :D RF Title: Re: A and B stroke piston weights and other questions Post by: RFbuilt on June 19, 2011, 11:32:27 am sorry i realize a hot street engine is as vague as it can be LOL
to clarify, a 6000-6500rpm kind of motor |
