For a 340 to make about 500 it needs to make peak power around 7200 and for that you need some really good heads in the 270+ range and a cam in the 255+ @.050 with 1 3/4 headers and an 800+ cfm cam. Solid roller in the .575 range should make a high winding 340 make 500 pretty easy with better torque than a F/T.

I've always felt 450 was pretty easy to attain and still be streetable, even with a hydraulic cm and a 6500 redline. i want to see if anybody has ever made a bonafide 500hp with a stock stroke 340 that was Street driven.

Darryl.....I'm so tempted to try Goldmemember's solid F/T on this thing and I might just yet....with the wheelbase on this thing I want to "ease into the combo so i'll start with a slightly milder and 500-700 lower RPM cap and see how it goes....hte bottom end is there EASY if I want to turn up the wick
