Hey, I am new to this board but have been viewing the threads for awhile. I am in the process of putting a big block in my 87 Trans AM and was wondering if my power steering pump brackets from my small block will fit the big block. I really don't think they will. How about the March power steering pump brackets, they are pretty expensive but I think I will need a new pump to use the brackets. I've even looked into an S-10 manual box but have my doubts about it turning the tires with so munch weight on them. Any help would be appreciated. Thanks

 

You need BBC brackets for everything.

I use a manual box with no problem. A BBC is only about 100 pounds heavier than a SBC. The hard part is trying to turn at low speeds with wide front tires.

 

this is my second summer street driving my car with the 454 and S10 box. it really isn't that bad.

 

That’s cool so what about the March power steering brackets #mch-20150 in the summit catalogue. If I used those brackets I would probably have to buy a new power steering pump right? I have already purchased a March alternator bracket so the power steering bracket would go well with the rest of the engine. As for the manual box I plan on using the stock width tires and am not going to put skinnys up front for a while or maybe never. So I’m not to sure 100 pounds is about the extra weight I expected plus I made sure to buy lightweight parts if possible anything that could be made in aluminum was except for the block.

 

I've been using the s10 box for a couple of years now with no complaints.

What year S-10 box should you use?

 

85-90, some s15's will also work.
