Ok, so I have a few questions on building the next stage for my Dakota. As of right now its heavily built bottum end 360. I'm in the neighborhood of 370rhp. Now, I'm about to PCS overseas and will be leaving my Dakota with a good friend thats also a builder. I'm going to have him re-work the entire thing, all the drivetrain.
So, my main overall questions are in relation to HP to MPG. I know thats almost an oxymoron in terms of performance. But, I'm not looking for a 10sec truck here. A nice high 11 or even 12s is fine for me. I also would like to make it reliable and drivieable. Thats the kicker. When i return home I may want to make this my permanent driver. So, the questions boils down to is what to do.
I know some people are doing the HEMI swaps and getting HP and MPG and reliable, and a buttload of aggravation in the process. I have the top end already so I'm thinking I can stick to this route and build a 408. but how reliable can a 408 be if driven daily? Better yet what about mileage? My truck already gets 7mpg on premium.
I know some do the 727 swap, that to me can't help mpg. What I'm looking for is at least 10/11 with a nicely built 12 sec running 408 stroker. I have the 4:56 gears too. So I ask the experts, can this be done? 400ish RHP, reliability, 12ish quarter is wanted, daily driven, and maybe 10 MPG?
I know their are a ton of motor experts out there; I'd love to hear from them. I'm no where near an expert on motor building, just know enough to get me in trouble. Funny thing is I can work on multi million dollar military jets...go figure. Anyways, comments requested please.
