I am thinking about putting together a fairly cheap & kind of experimental 440.
I have a mid 70's 440 block std bore, very light use as the cylinders are still within spec.
I bought a new set of Silvolite pistons with 1.912 CH. I originally planned on shaving block & closed chamber (75cc) heads to get the CR up.
My new idea is to use a set of used Howards forged alum hemi rods which are at least .075 longer than the LY's, this should give me a CH of 1.987. Also going to cut the small end bores to 1.094 or so to float the pins and hold em in with buttons as the pistons are not grooved for clips. I may be talkin with my head up my ^%# but these parts came to me pretty cheap.
Block & crank $100, Pistons $100, Rods $50. Rods weigh about 710 grams, pistons 832 grams (pistons too heavy??). I would zero balance it and dont plan on racing or reving the crap out of it. Anybody think this will work? or should I stop dreamin.
