how hard would it be to transplant a 93 chevy 305 into a 2000 ranger? anyone done it yet?
 
do not put a 305 into anything. the heads don't flow for crap. and they don't have much displacement. the 305 is identical to the 350 from the outside. so you might as well do a 350
 
im not looking for monster power i just have a 305 with a trans sitting in my garage not doing anything. how hard would the wiring be and what about ujoints? id like to use the ranger axles anyway. Ill also need to get custom driveshafts right?

then you are headed the right direction. the '94 305 only makes like 20hp more than your 1999 4.0l

get on to the chevy forums to learn how to wire the efi to stand alone. so all you will need is the switched ignition wire. but its a fair amount of work to do. the holley projection kit is extremely simple to install and uses a stock chevy-style throttle body and only 2 sensors. and they are going for sale used around $400, or new for $999

secondly you'll need a chev trans (even if you had some sort of bellhousing adaptor your stock trans won't hold up anyway) and you'd need to marry a chev trans to a chev t-case (the adaptors to a ford one are like $600) and the problem is that except for very few all chev t-cases have a passenger side drop on the driveshaft. (some trucks through the '90's had a driver's)

i took my driveshafts down to the driveline shop and they put the right yokes and shortened them to the right lengths for about $120/shaft
 
i might end up divorcing the transfer case if its that much of a problem.

I would sale the 305 and find a Explorer 5.0 to put in there. If you insist on doing the 305 becuse you have it then if it is in the budget do a throttle body injection as it would be the easiest FI swap you could do with that GM engine.

305 heads on a stock 350 are a performance mod (seriously)....... :icon_rofl:

The 305 is however like chevies bastard engine (but that doesn't make it neccessarily bad at all....... like anything else they can be modified, if your hell bent on a 305 thirdgen.org is the absolute 305 horsepower resource.

due to much smaller combustion chambers 305 heads will raise a 350's compression by almost a point and a half. (if that what you mean by "performace) but have much smaller/ poorer flowing runners (which is what i originally posted)


maybe you got it backwards and meant that 350 heads are an upgrade for 305's? a 305 with 15cc domed pistons to compensate for the larger chambers to equal the same compression with make loads more power

or maybe you meant, the 1999+ 305 vortec heads which never came on a car (only boats, catalogs and crate engines) which have the same size runners as it's 5.7l counterpart. but the smaller 58cc chambers thus giving more compression and the same flow (which i am currently running on my 350 bII)

but i doubt you meant either, and are suffering some delusion that 1993 5.0heads out flow their 5.7l counterparts so.........

what i originally said still stands true, and to agree with others who posted here if you're not looking to make a lot of hp anyway the 5.0 would be an easier swap.

I'm not delusional....... i drag-raced sbc's.

Increased compression is the goal of the 305 heads, but you take a loss on top end due to the smaller intake runners. Youd be good to run a set of flat top pistons on reg gas.........

On my car I just went with a set of 375hp double humps though.

the 305 is far from the dog everybody makes it out to be though ( i didn't like them, but I always loved seeing a high Hp 305 at the track)

i miss the days when i "drag-raced sbc's" ............ but i would bet what you call "drag racing" is not what i call drag racing (much like what i call "delusional" is not what you call delusional)

here's a photo-scan for you:
(look at the front engine mount plate you can see where i put spacers to make the small block mounting tab extend to fit the longer big-block)

and here's what a 2-second google search of "305 heads on a 350" brings up:

yeah never coming from the factory with more than 255hp is not a dog................ i think even the ford 302 has a better record than that

why sacrifice anything in the name of compression? especially flow? that's the kind of white-trash "only want to spend $25 on parts" way of thinking that some guy in his back yard with a 1983 camaro half-primer and half rust would do hoping to make his 17-second car a 16.8-second car.

that swap isn't even worth the price of the gaskets needed to do it

i just found a chevy single cab longbox 4x4 350 w/5 spd for $300 if i used the chevy all the way back to the yolks, would the 8.8 and dana 35 hold the power or will i have to change axles too?

well i'm sure your axles would be fine for a stock v8. just keep in mind that if you don't use the chevy axles your t-case needs to drop your front driveshaft on the correct side. i used chevy all the way to the tires
 
the reason i want to keep the factory axles is im trying to keep the truck the same width it is now because i can fit in alot of places a full size wont. Also I keep hearing strait axle conversion from everyone buti like my independant front. What would i gain by doing a front axle besides the obvious cv shaft problem. Thanks.

a lot of chevies came with driver's side drop t-cases, a lot of s-10's did, and the 4.3l s-10 used the same 4l60e transmission that the v8's came with, and the same bellhousing so you could find a married trans/t-case from one of those (or any other driver drop chevy with a v8, or a 4.3v6) and would be fine as far as power goes. you'll just need to have the driveshafts shortened and the correct u-joints added

Keep looking thru uncle henry's....someone will have a rusted out ford truck with a 5.0 or .8 cheap. I got my 100K mile 95 5.0 for $200, complete with rear springs busted up through the bed floor, but it runs and runs good, drove almost 30 miles home, and is complete, cept for the body parts that rusted away.

Plus more 302's have been put into rangers so there's more help readily available.

Actually I might know of a $100 late 80's 5.0 5 speed 4x I'll check on tomorrow!! Its north of bangor bout 45 miles.....
