imo, LT1 doesn't have the best rep when stacked up against the LSx's. Maybe it'll up the value of the C4's. Too bad they didn't start with L98 and maybe use the LT1 name for the ZR1's....

What I can not believe is they're still (still still STILL) building push rod motors. This maybe the greatest engine ever built, I don't know. But it's starting to remind me of Harley and how long they kept producing 50's tech and selling it as the newest thing (and for top dollar in their case)....

You gotta luv that cad animation though. Wouldn't it be great to an interactive cad on your current vette? Where it could do animations of parts removal and bolt patterns n such? Show you where the smallest part is (or at least suppose to be), and the procedure to remove it...

I don t know, I have some pretty fond memories of my LT1 cars ...in 1970 when the first generation hit the street ,it was the bad boy on the block...370HP ,solid lifters 7000rpm.., for its day, quite impressive...you make a good point tho about still using pushrods, maybe its because of the Fuel Management System
