Big Block install Q's

[kwmech]

Not quite like the other questions, as I have been doing this for years although I have always used the short water pump. I am pulling the diesel out of my truck and going to a 454 tbi. However the 454 is out of an 88 with (of course) the long water pump and a serp belt for the w/p and alt. and a V belts for the AC and the PS. I was measuring tonight and looks like the fan clutch will be into the radiator. According to everything I measured the 6.2 overall from bellhousing mount to water pump is 27.5'' long ( I have 1.25'' from the end of the fan clutch to the radiator) and the big block with the long water pump is 31.250. Are you guys running electric fans or going with the short water pump that is 2'' shorter? I may be looking for a set of pulleys and brackets for a short wp.
