ya...well that's not the first time i've been accussed of cutting new ground, LOL. in my world it's really not all that edgey. as some on here know, the car in my avatar is a 441 S.B. & off the top of my head i think the bobweight on that is 1410 gms. to get it down, titanium pins are a must, smaller diameter pins (.866"), at least .043" x .043" x 3.0mm ring pack & smaller rod journal diameter. i routinely use Honda size (1.889") & right now i'm doing one that is Mitsubishi size (1.772"). by doing that bearing speed is slower, crank is lighter, bearings are lighter & rod big end is lighter & smaller overall, which in turn also ends up giving you more swing room if you will. now this stuff is all naturally asperated so it's a little flyweight for a power adder combo, IMO. don't get me wrong Todd, 1600's is not heavy, i'm not saying that but if i'm going to do something for me...well, lets just say it has to be interesting. thanks again for your time Todd. appreciate it & didn't mean to get off topic of your original thread.
