'Other' Engine Conversions All other engine swaps. Not for discussing V-8 swaps
most all understand this to mean the common v8 gassers i am sure, at least that is the way i have always taken it. but we have swap forums, hell this entire site is dedicated to improving and maintaining these things..but specifically these areas have to do with swaps....whether turboing or powertrain replacement ect.....
i have absolutely no doubt i can get 20 plus cruise mpg with a 351 or 302 in a low 2wd truck with tall gears and tiny tire. efi or carb...no problem.
i wouldnt suggest a bigger diesel swap n such a case either...and when i say "bigger", i would be starting with a 4bt and be going on up to psd's being bigger diesels.....that is alot of range but thats whats out there and REALISTICALLY DOABLE.
for the said 2wd case above a 3.3 cummins or stock(well, stock everywhere except the U.S) psd type ranger setup would be key. and potentially get twice the milage and easly pay for itself a few times over 100 k miles in a 4.0 truck. these engines can also be tuned to outperform most of the american factory offerings
significantly which is only
icing on overall costs....not something that has to be done...most importantly is alternate/combination fuel capacity.
and thats usually the defining deal too isnt it. COSTS.
just how the hell do you nail those down anyway? generally speaking nicely done gas v8 swaps cost 3-4 k and take months for the average diy guys.
but thats a huge variable.
fuggin huge variable is this whole rbv deal....how can you one size fits all a rbv?
one thing to remember is real low mile good running high power 275 plus hp 302-351's that run on pump gas and built for the daily grind are not readily available anymore. or rather were
NEVER AVAILABLE ........
so your buying fresh rebuild or building yourself....
any way even if you do find a decent running take out ... who the fawk wants a sub 200 hp wheezer anyway? ohhh ohh sign me up?? right?
RIGHT?
sooooo where does that bring you for cost effective swaps that make sense over a 4.0??? because the reality i am in here is (this is generally speaking of course) good solid mid setups (say 275 hp) with stoutly built and or fresh trans (and t case if applicable) ect and basic freshen of the trucks they get swapped into...carb or efi are easily 4-5 k done "ok"... .
personally, i cant at will, build a 350+ hp 351 thats
long life and somewhat able to get good economy for under 2500 bucks without careful shopping which is also time consuming, then i still have to get a stout driveline to back it. either way my best hope is 2500 for a complete ready to swap package.
yet....(again, this is generally speaking of course).... i can get a solid low mile late 5.3-6.0 setups radiator to t case outputs complete for 2500. thats pretty hard to beat.
i realize depending where a guy lives usually depends on whats the most cost effective thing to upgrade to. i suppose fresh 351 4 bbls with motronic ignitions with 250 dollar non smog intakes with fresh 700 cfm carbs making 350 hp and getting up to 20-25 mpg (IF YOU CAN ACTUALLY KEEP YOUR FOOT UT OF SUCH AWESOME NOISE) even if swapped in a 4x4 ranger!!!....
surely, these are falling out of the sky for 500 bux in some areas of the country. right?
more important to me then any of that shit is this, why do you need a powertrain upgrade.?.?.?.?.? or at least why do you think you need one?
this is the real thing to consider.
in my case, which is common here by the way and actually that of the original poster, i am asking to go past the capability of the 4.0. i have a large, heavy, 4x4, sas, daily driver that is multi use and for me at least 35 k a year of road, track, and trail passes under it.
no matter how hard you wish, a CHEAP 351 is not going to get 21 mpg in my rig. certanly a 351 is more then enough to have a blast in it though.....a 351 is an excellent engine for big trucks that dont tow like these rbv's, no one doubts that. also, in my particular rig efi is necessary but adds no costs.
MOST IMPORTANTLY
a 351 is not simply more inexpensive then a 6.2/6.5 N/A or a mechanical turbo diesel to swap into a big sas ranger. depending on goals it sure as hell isnt really any easier. i cant see a rational explanation for that claim that its easier and or cheaper
i mean...how can you come up with that?
HOW DO YOU KNOW ITS A HARDER SWAP??
seems a guy can still get complete cucv rigs for 1500 bux too or at least thier powertrains and spend maybe 3-600 bux putting all that shit in a ranger and end up with a rig that can run alternate fuels.
of course a na 6.2 is a turd compared to a 351. but nonetheless time in sourcing would be similar along with costs and swap difficulty in general.
swap difficulty is nill if your willing to run a 3 inch body lift, run an alternate steering box or relocate the oe unit, and mod the core for a good radiator.
so if cost and difficulty is so similar, its down to options and intended use.
i have performed/assisted in many engine swaps to these rbv chassis...from wrench a thons to straight out hire and drive three states away, and would expect only questions from those that dont do these types of things. when i started doing this there was no internet to parrot...and i am glad too. there is always as much bullshit in these threads as there is help it seems.
in the end it is simple
i am able to drive my rig daily again and i am pleased to have taken the time to install a diesel.
and for sure, its a old diesel. its noisy and stinky and rattles.... especially when cold compared to the gt40 spec engine it replaced. these things i have found to be acceptable.
others surely will not....
for a light 2wd strip street cruiser, or a dedicated trail rig, i for one would not use any diesel.
but for a heavy sas rig on 35's a 6.2 turbo backed by a well built 700 is a great choice. it will make a 351 look stupid and still pull 20 and have alternate fuel capacity
on a 2wd daily though, a vw/benz type td or a 3.3 would be ideal. though i have no experience swapping those yet in this appicaton.
the 351 is fine for anything else.....though a 5.3-6.0 would likely be more cost effective and time effective. thats not as much opine as the blatantly obvious either...
so to those that will reply in these swap forums i have to ask...
WHAT CAN
YOUDO
??????
what have you done???????????......that can help people attempting to swap or are gathering data to effect a successful swap???????????
