Hello ! I bought a crate 5.0 320 HP back in the 90s. You guys talk the talk and walk the walk. It was excellent in all . I reworked the GTX heads, 1.72 rockers, and 9# boost.. I have been racing since age 14 and am 80 now and still look forward to drag season. On the table is a 347. Carol made it till 90. Life is to be lived I have a complete library of "Hot Rod," and many other good car magazines. My dad when living had a stable of very fast homemade Racers. You guys do a valuable service to young serious racers. RON ELLIS ,
