I want to replace my 302 with a 351 dart block engine. Am I going to run in to motor mount issues. Also, I know my current 302 4into4's will not fit so I will be looking for a new set. My current set is relatively new so maybe I can sell.

Both engines use the same motor mount.

Same motor mounts, different headers. The 351w will be taller so look for air cleaner interference.

Just to add... The 302 has an ~8.2" deck height (crankshaft centerline to head) and the 351 a ~9.5" deck height. Everything else with the crank has the same dimensions.
In addition to added height, it'll be a bit wider too.

And it will be worth every inch.
