Hi I have an 84 Ford f150 with a 300i 6 in it. I was wondering how I could get a good amoumt of horsepower out of it

low restriction exhaust
better intake
stouter cam
more compression
head work

If simply going for the best gas mileage with a stock engine, can a "low restriction exhaust" be accomplished without replacing the stock exhaust manifold?

Yes, it will help, but a higher flowing exhaust manifold, e.g. EFI manifolds, will certainly yield a greater benefit.

This maybe a dumb question but how do you get higher compression ratio. I'm new to the engine building scene

Mill the head. If you are doing a complete rebuild , mill the top of the block. The piston is general about .040 down and milling the block will up the compression. Different pistons can up compressionalso.

Install a 240 head! The Ford 300 in-line six head can be replaced with the head off of a 240 cubic inch inline six. Smaller combustion chamber gives a higher compression ratio!
