Sad that GM had to wait 8 years to get back to that same level with a pushrod engine....
You need to do a little research. You know why the LSx engines are so damn good?? Research them. The technology in the LS7 could blow your mind for how much one costs and what you get outta it. The LT5 was engineered by GM, except for the help on the heads from Lotus. Oh by the way, the LS7 SMALLBOCK is 427ci and revs to 7200rpm safely. Doesn't sound lowtech to me. BTW, a crate LS1 would only set you back $6000 with computer and harness!!! If you want a cheaper route, get one from a junkyard for about $1000-$2000. A swap harness with computer only runs about $700. Yes, pushrods are a little inefficient compared to OHC designed, but there is a reliability and simplicity benifit that overwhelmes the efficiency. As far as LSx performance, all I have to say is John Lingenfelter.
