500 from a 440 is so easy, a caveman could do it!

10.5 compression, eddy heads, intake, carb, cam, headers and you're done.



my 383 block has a 440 crank in it, and is bored .060 over, so it's 438 cubic inches...or, a .010 under 440.

with out of the box edelbrock heads, an RPM intake, flat top pistons at zero deck for 10.5 compression, a comp XE-275-HL (around 230-235 duration @ .050 if memory is correct), holley 750 HP, and regular ole headers, I made 505 hp and 535 torque. my torque curve was also flat, over 500 from 3,000 rpm through about 5800 rpm.


made for a GREAT street motor!
