Installed big block (502) in 67. Now my throttle arm has no travel as it hits the back of the block. Solutions? Also, wiper motor ain't gonna fit either. Solution? Any help would be greatly appreciated.

You might get more help if you post the make and model you're working on, details on the top of the engine like manifold, fueling ect, and post pictures of the problems.

My neighbor ran into the same problem on his 68 Camaro. He had to replace the entire mechanical rod type linkage with an aftermarket cable setup from Lokar to include their gas pedal. It's not as smooth as the original setup but works.

They're not cheap but the aftermarket has wiper motor assemblies that fit inside of the cowl to solve this clearance issue. My neighbor's big block does clear the factory wiper motor but may be because of the valve covers used.

I can get you some pics if needed.

GM made these car with big blocks, these shouldn't be any issues, unless the valve covers are too high and your having an alignment issue with the rods and gas pedal lever, mine was bent and wouldn't open the secondarys, take a second look and see what the issues are,
