Magnum, Magnum R/Ts

Get down to a newsstand and get a copy of the October 2008 Popular Hot rodding. They built up a 318 that cranked off 425 HP with a 9.7-1 compression ratio and Magnum heads. They used an aftermarket Magnum replacement head sold by Enginequest.

The cool thing is, they sell these heads for use with both the Magnum style intake and regular LA series manifolds!

No reason this wouldn't also work on a 340 or 360, just have to change the part numbers a little. Stock steet hemi horsepower from a stock stroke 318!
