i had planned on puchasing a 350 sbc and decided on keeping the cat, 3 inch, and 1 5/8 headers with the american thunder made for the 88 year iroc but i allready have a 327 in the garage ready to be built and the guy selling me the 350 gave me the block ID i ran it and it came up a 305 so i'm going with the 327 cause i wanna have it done by summer but will the 350 package i pieced together work for the 327 too?

 

Yes.

Assuming your planning was sound for the 350.

 

Sux bro, dude who sold me my 350 told me it was a roller block and it was not. Well it was but it wasnt set up for a roller set up, so it still had the bosses for the spider and **** and i just had them tap and drill it and voila, a 4 bolt main 350 roller block w00t. Good luck.

 

I've got a quick question do the local muffler shops typically do mandrel bent exhaust or is that mostly just big companies like flowmaster?

 

Local muffler shops typically don't know the meaning of the word. All too many performance exhaust shops don't, either.

It's a special shop that knows what to do and how to do it properly.

You can get headers, y-pipe, cat, and cat-back that you can bolt in yourself. More than likely for less than any shop would charge to bend up a system for you, even with the standard crimped-down bends.
