aluminum rods on street ride not a good idea!! titanium not a good idea either... titanium are ok on n/a engine but not for turbo or nitrous engine. they are light but will not take the abuse. and aluminum are subject to stretch .
reason i asked is i have a set of manley alluminum rods that i aquired for free was thinking about building a lb4 shortblock as a new one with splayed caps and a balanced rotating assembly just have them and wondered if it would work truck is supposed to have h beams in it now but i dont feel there much good without a good splayed cap and balanced assembly just worried to push it to hard till ive had my hands on it that way i can blame me thanks
