For a 72 Skylark that had a 350 and converting to a 455... I would need a short nose (not a long nose) water pump correct? thanks
Larry, What about fan within shroud for each pump length? Do you know why they changed to a longer pump? Just curious.
Some 72 GS cars had the long pump, my 70 has a short pump. Not sure there is any rhyme or reason. Here is the applications from the TA catalog,
Thanks. I saw that.... so next question... if the motor came out of a 72 Riv (full size car? That probably has a long pump) and i had all the original 455 Riv brackets and accessories and belts... should i reuse all of them and the long pump for my 72 Skylark convertible? Or should i go with a short pump and only need to get a short pump pulley or would i need ALL new pulleys? Thanks
I would use what you have for a 72 Skylark unless you want to make extra work for yourself. If you are going to use a 70 fan shroud, the short pump might be better.
No shroud yet. Its just a decent driver and not all original so i am keeping an eye out for any 455 shroud not too picky on being correct for the year.
whats the difference between 70,71 and 72 455 shrouds? besides maybe a radiator hose support hole/bracket on top?
The 70 shroud has a 20” opening, 71-2 shrouds are the same for all intents and purposes, but the opening is 22”. The 18” fan fits great in the 70 shroud but gets lost in the 71-2 shroud, use the 5 blade 20” fan for them.
