v6 vs straight 6?

what is the difference between the older v6 and straight 6? I've heard really good things about the I6 but was it any better or worse? would one out perform the other or get better gas mileage? and what years were the straight 6's used? and how would they do with 6/8 inches of lift and 35 inch tires, with maybe a 4.56 gear ratio? I'm afraid that they wont be powerful enough for it and my mpg will suck or it will just die. Thanks.

Re: v6 vs straight 6?

I think the Ford 300 straight 6 was one of the best engines ever made. I know a guy that has well over 300K on his in a F-150 and still going strong.

As for the lift, tires and gear ratio, I'll let someone else ring in with that answer. I'm not sure

Re: v6 vs straight 6?

The I6 in question is the well renowned 4.9L, yes?

Otherwise, 35" tires with 4.56gears will ruin mileage - guaranteed. With the right aftermarket transmission ( WELCOME TO RICHMOND GEAR ) you might only lose 5-10% in fuel economy. With the greater expense to modify the vehicle to get better mileage with the lift, gears and tires won't show any significant benefit. I bought my 'truck' (SUV in disguise) for what it can do - tow, haul and guzzle gas in the process.
