ok their is some fairly knowledgeable people on this forum. i been reading that some people fit 380 cams in the 3.5 do we need to use the 380 valve springs or can we just shim up the 3.5 spring s.
any specs on the two cams or springs
thanks in advance

I've fitted the 380 cams with stock 3.5 springs etc. I've been told it should not be a problem.
