351w problems
My 77f 150 has a 351w in it if I'd have to guess it gets around 1 mile per gallon.i know these engines push around 9-12 mpg on average. Could this be because of a cracked intake manifold? It takes a little to warm up (3-5 minutes.) the last owner said there was a cracked intake manifold but was repaired with JB weld. Could my bad mpg be due to the crack?
