We race these engines because we love em! Many classes demand a stock head or block. Wringing more speed out of the same engines our forefathers used in the same basic class they ran in has a taste like no other. To best a speed in a vintage class means literally to best every person who has ever raised the bar in that class since it's inception back in the 40's. Every problem we have discussed here must be overcome. If you look at the vintage records, you will see most of them are quite respectable, LSR or Drag. You can't go down to the local speed shop and buy the latest trick part and expect to succeed, you design and make it. Vintage racing has the greatest challenge because all these problems and for me and many others, the greatest rewards.
