I am going to be buying an older mustang soon. I would like to put the biggest engine I can into it. A friend of mine said the ’67 fastback was the best choice. I dont know a lot about older mustangs yet. Im trying to find out the differences in the fastbacks from ’67 to ’69.
It is indeed possible since the GT500 WAS a ’68-’69 bodystyle fastback, and since all available engine options for that model mustang use a standardized 4 bolt main mounting system. the changes to the mustang between ’64 1/2- ’69 were minor and mostly asthetic, these “body-style” changes occured as follows, 64 1/2- ’65, then a change for ’66- ’67, and then again for ’68- ’69.
Define GT500, a sixties era Shelby GT 500 engine is a bolt in swap, a 2007 GT500 engine is going to be tough. It will require hand fabricated exhaust, mounting brackets, linkages ect. Plumbing in the inter-cooler is going to require more fabrication. After it is bolted in wiring the electronics to make it operate properly is going to be expensive and time consuming. As the last answer says, buy a Roush or Ford Racing crate engine, it will be a lot easier and faster in the end.
Put a Ford Racing 429 Super Cobra Jet Crate engine in that car.
I swear to you, you will have power with Astronomical Proportions.
Are you talking about the old 428 GT500 engine or the new 500hp 5.4L from a 2007 GT500??
Ford had some REAL MUSCLE back in the 60′s. 427 overhead cam was in the Shelby Cobras(Bad to the Bone) 428 and 429 Cobras and Interceptors were to. Easy to work on and carburated. Oh yea, don’t forget the BOSS 302, a small block but you could get 7500-8500 rpms out of them and they were also BAD TO THE BONE!!
Yes, but you may have to modify the shock towers in order for your headers to have clearance.
You should also spend some time stiffening the body (60′s mustangs don’t have a real frame – they are more like early attempts at unibody). Most people that put a huge engine like that in an old stang will actually build a frame – sometimes even to the point of building a roll cage in the passenger compartment – not a bad idea.
You will also want to put a more beefy transmission in – and probably upgrade the driveshaft and rear end.
Keep in mind that the extra weight will make it necessary to upgrade the suspension, and the extra hauling-azz you are going to be doing is a good reason to replace the brakes too (actually, if you have an old stang, you should upgrade the brakes regardless).
It’s a “bolt in” swap. You can use factory mounts, linkages and all accessories. I would try for a Roush 427R which puts out 550 hp/535 ft lbs of torque. Visit the website (see sources).
