Btw: The donor engine has the same deck height as a 351c! The swap was done to a Cleveland using the donor engine's stock intake and fuel injection. The intake had to be installed backwards to clear the distributor... Edit: The donor engine's TB is right over the water pump.
They look like Dart pro LS1's http://static.summitracing.com/global/images/prod/large/drt-11010010.jpg
Who'da thought those would fit SBFs?!? I think it's cool as heck. Impractical, but still cool. I will surely get arguement here, but IMO the LSx engines are the best production pushrod engine ever made. A great deal of that has to do with the heads in particular. The top of the port is made like that so the injector can protrude into the port and spray fuel directly on the back of the intake valve. Good stuff. What the guys in the thread on 460.com don't realize is that the truck LSx intake is known to be the best intake out there for those engines. The car intakes are the way they are soley for hood clearance. If they put these heads on a Cleveland, they could use the truck intake, and the design of the intake wouldn't put the TB into the dizzy.
Should have just put the entire LSX engine in there. The bottom end is better than anything Ford ever made and it's an Aluminum block too. Ah well, at least it gives the owner something to talk about at cruise ins....
Those engines are in so many vehicles now... All the GM trucks since 99 or so, various Caddys, Vettes, GTOs, Camaro/Firebird, and I am probably forgetting some. The things are everywhere. The valves range from 1.90 to 2.05. The heads are continually improved... The intakes from the trucks are very similar to the 5.0 Stang intake. All the heads are aluminum, and intakes are all plastic. The blocks are aluminum in cars, iron in trucks.
