I did that in 74 with a 426 street wedge and a 383, same heads, cam, carb and the 383 Torker instead of the 440 Tarantula, the 383 was used after I spun a bearing in the 426 so I could still bracket race every week while I built a new engine. The 383 had almost a point less comp. and about 80k miles on the shortblock, it ran within a tenth and a mph of the average of the 426.
