73 bug
 

What types of modifications do you sugest to get better gass millage more horse power.

RE: 73 bug
 

Hard to do both, when you get more horse power you loose gas
mileage, The only thing I know that will work for both is to have
the heads cut ( shaved) for more compression, that will give more
power and fuel mileage. cut the heads about 65-70 thousants.
dont go over 9.1 to 1 compression ratio. that would be about
140 lbs . a factory new engine with a few miles would have about
120 to125 lbs
