1973 429 Thunderjet worth updating?
Looking or valued comments regarding this engine. It has been balanced/bluprinted with new hardware, but the heads stayed the same (190HP rating). Does it make sense to put new 10:1 or 9:1 heads on it, with new manifold / carb / cam to increase the HP? I really was interested in about 350-450 hp ratings. It seems I could get into this for about $3500 vs a new crate @ $6500. But looking for your advise. Thanks. Steve
