Generator variations from a 302 plus a 351W
How big the engine obstruct may be the main distinction from a 302 and 351W Ford engine. For the intake manifold, the 302 block has sixteen bolt holes, but the 351 block only has twelve. The pinnacle bolt pockets around the 351 are also larger. If you want a bigger displacement, you can replace the GT40 heads from the 302 engine with 351 heads.
The 302 generator can be a 4-stroke, 4.9-liter motor. It created 4.9 liters and was best referred to as “5.” motor in Shelby GTs. The 302 engine was depending on the 289 generator but was stronger since it included more nickel. The very first 302, which in fact had 210 hp along with a 10.5-to-1 compression percentage, was released in 1968. It was made approximately 1995.
302 versus 351W engine difficulties

engine issues with a 351W
It’s essential to establish the root source of any 351W Ford engine concerns you could be getting. The back main close is among numerous issues that can lead to gas leakage. This close off is found where the crankshaft connects towards the transmitting in the back in the generator. The essential oil is eliminated from leaking out from this close. Even if you don’t drive it commonly, it could gradually become dried out and cracked. Making the vehicle stay nonproductive for a time could also turn this into difficulty even worse. This seal is composed of lean rubberized, that is at risk of drying out out and cracking.
The 351W posseses an exhaust manifold that fastens for the engine block’s exhaust ports. The engine’s exhaust air flow is consequently sent throughout the tail piping and in to the exhaust system. All of the four cylinders around the 351W’s two exhaust manifolds.
