I have a dilemma with the 455. In the mean time I'm looking for something to pull thisboat around till I can do it right and get my motor finnished. I found a 400 locally freshly built by an enthusiast at a negotiable $900. He has 4 pontiac engines around so I see his thinking is in the right place. But, I'm looking for opinions on this build. thanks in advance. any flow info on these #11 heads off 1970 350/400 running 255/265hp at
8.8-1 cr


I do an engine every year for a winter project but there's no vehicle to put this in.

-short block is from a 1973 Catalina wreck with low miles, very clean and only inspected, not taken apart and rebuilt. Has all 6 mount holes (many don't) , so can go in any Pontiac Firebird, Lemans, Ventura, etc.
-pistons are flat-top 10 thousands down from the deck
-heads are #11 (73cc) from a 1970, so we have nearly 10:1 compression and will require premium gas
-heads have 1.96 intake valves, press-in studs, and are tapped for exhaust manifolds (included), not headers--but can be done before installation
-New Felpro head gaskets and NEW head bolts
-gaskets changed throughout motor
-New Summit 2801 camshaft and lifters, degreed 4 back for better dynamic compression, with new SA Gear double roller timing chain
-stock oil pan, 3/4 windage tray, and 1973-vintage 4 barrel intake manifold (needs EGR or can be blocked off) cleaned and reinstalled
-complete with water pump installed
-no carb or fuel pump
