Frustrated!! Lingenfelter procedure?

[Paul Workman]

I bought the book by John L to "scratch an itch", i.e. read up on the procedures he uses to tune up the LT5 to get 500 hp - plenum/head porting and cam timing.

Really intriguing is the FLAT torque curve from 2800 (beginning of the graph) to 7000 rpm, where the torque remains at or above 400ft# across the band. But, the book left me hanging...All that was said about the LT5 was, if (the reader) was interested in making the LT5 a screamer, they (Lingenfelter Engineering) had "a package" for us. I spent the price of the book for that one sentance??

Where might a guy find a decent book to curl up with that covers the LT5, and in particular, what about this plenum/IH/heads porting? (I just bought my Z, and I don't plan to change a thing for the time being. It is more of a thrist for knowledge, at this point, I recon.)

Thanks in advance.
