Good grief! I can't believe the "bitchiness" of some of the small block guys in this forum. Small blocks are great, I had a worked 360 in my car for a few years in the late eighties; but the i went big-block. Wow! what a difference! And that was with much the same sort of combination as the 360. For a very hard-driven street car(& i'm talking 70-135 mph)they would jail me today,i guess)the small-block just couln't compete. I used the 440 for 18 yrs & then i went with a 440 Source Stroker. Oh boy! The smile just couldn't be taken off my face. Cubes equals Torque,& that rules. With 2:75 gears & New-Process I do 12:00-12:25@ 117-118mph with a 4000 lb Charger. As for Turbo's. Great! Thats probably what i'll play with next. But isn't that just artificially making a small-block think its a big-block. Kinda kills the argument some of the replys have used. The stroker has all the parts except for crank,rods & pistons. It gained one full sec: & 4-5 mph through the 1/4,& gained 5-6 mpg imperial. Better volumetric efficiency I guess as the shorter rod ratio along with bigger cubes reading all parts as being smaller than what the 440 see's. Mike in New Zealand My
