1971 chevelle ss 402?...

[TURBOSCHILZ]

Sweet, thanks for all the info fellas, sounds like I've got enough info to get me started... As for the radiator, it is an original SS car with the larger radiator, I think 3 core, with the 4 bolt top cover, do I need something more than this?... I'll list the casting numbers and codes below if you guys would like to take a crack at them, otherwise I do know that the block itself is unmodified and the stock bore...

Block:
3969854 PASS HI PERF
T0510TKB
E4-71

Heads:
3993820
26-7T (or 1, not sure on that one)
201

P.S. One more quick question, did a 1971 Chevelle SS BBC w/o ac and w/o smog come with a long water pump or a short water pump?... I believe that my stock 245hp 350 has the long pump, it also has the 4 blade fan w/o clutch, I would imagine that the 402/454 would come with the clutch fan, is this correct?... If so, how many blades?...

Thanks a lot fellas, you guys ROCK...lol
