The 194, 230, & 292 fit also but might change the comp. ratio. If you have power str. Or a/c the brackets will be different. Get an 71 up head they have better valves & seats for no lead gas. Also the exhaust hook up will be different.

My 250 engine is from about '76, separate manifold. I've seen a few even later than that - they seemed to be using up old stock here and there. Best bet is eBay or your local wrecking yards.
The best use for that integrated manifold POS is a boat anchor. | | | | | Joined: Jan 2005 Posts: 52 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 52 | Wow, Thanks guy for the info!
