Re: Heads & cam LT4 Don't waste time with the LT4 hotcam Lt engines love a lot of lift. If these are stage 2 heads try anything from a 550 to 620 lift cam custom ground preferably. Keeping the valves open longer and larger heps cool the LT1 block since it is cast and not aluminum as the LS1.

Re: Heads & cam LT4 I know two people who could easily get you over 400RWHP with say a GM# 847 cam <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Re: Heads & cam LT4 I love my cc306 cam <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I use heavily ported stg. 3 MTI LT4 castings w/ 2.05/1.60 valves .
