Hey guys,My old man has a 1986 Chevy suburban with a 350 which recently locked up. so ive got a 327 im gunna put in there and i was wondering if the exhaust manifolds will bolt up to the 327.

[DoubleVision]

yes they`ll bolt up, however, the 327 doesn`t quite have the torque of a 350 to move a heavy suburban, If the 327 is stock, I would add a RV camshaft and a double roller timing set, this would give it more torque so the smaller 327 wouldn`t have to work so hard to get the vehicle moving.

Thanks for the replies. also i have run into another problem the 327 heads don't have any accessory holes i was wondering if you can drill and tap new holes or will I hit a water jacket or something. or is there something else i can do or am i just outta luck.

I had a pair once that had been drilled, they worked fine. I didnt drill them but it did work. in one of the heads they did hit water but it worked as long as the bolt was in it.
Hope this helps.
