I recently rebuilt my 93 300 4×4 which had 90 compression so i rebuilt it. Replaced every top end gasket, replaced the rings, adjusted the valves, did everything right and she runs great but still lacks SOOOOOOOO much power. it has nothing in the low end its just a dog. it gets up to the top speed but it just lacks power. i didnt check the compression yet, idk what the fuck to do. the piston and cylinder was in great shape told by a performance shop. help me.
