ok here the thing

i got a 1987 v-6 tpi and im kinda starting to get a little pissed off that everyone and there mother is passing me so im looking to change the engine. well i have a few questions

1.
i have in my possesion a 305 tbi out of a 1988 chevy p/u....it was free so no complaining there. how much changing of the wires and all that kind of crap would there be. i mean would i pretty much have to rip the meat out of it and start over. i know about the motor mounts the struts and suspension. would the tranny hook up as well?

2.
with that 305 tbi.....ive heard of ways to change that over to a carb. would that be better and if so how much would it take to change that over

3.
last but not least. i might be able to get a chevy 350 tbi not sure of the year, but that would be free as well. it just threw a rod and i can figure that out on my own. well if i get the 350, would the changes still be the same as the 305 or would it be completely different.

yea i know, i dont know much just yet, but everyone has to start somewhere thanks for all the help here

 

1 you'd need a V-8 trans. i'd leave the suspension alone.
2 id also change to carb. i'm pretty sure they make a specific intake man. to convert tbi to 4bbl.
3 go with the 350 its way more powerful and everything you'd have to do for the 305 will be the same as the 350.

 

you dont want to go through the hastle of a v6 to V8 swap and have a 305 that runs in the area of 16 second 1/4's with a tbi and no mods when your done... if i were you id hunt down a wrecked V8 thirdgen for cheap as hell n tear the crap out of it :-)

i dont know if i would take a free 350 that threw a rod over a free running 305... but either way you go, it will be much easier to convert to carb than it is to go TBI...

 

im not exactly sure if that one engine is a 350 yet, ill find out in a day or three. i am definantly going to rip the engine apart what ever i choose and bore it out and do mods to it and all. im not that stupid to just take a engine off the ground and throw it in and thats it.

i kinda do want to do the v-6 to v-8. i plan on putting this car up on blocks and i really want to get down and dirty with it. this way if i do this swap i will learn more about what i got. call it a learning experience. i know i know. "he will just find out the hard way" haha yea i get it but its something i wanna do. the engine is free and i can get most of my mods and everything for free too so i figure why not.

ok well i get the tranny part i figured that, but what about the wire harness and all. is that all going to need to be replaced and what not.

 

lol i know what you mean, im going ahead with the LT1 swap in my 86 V6 late spring/early summer, i want to learn the hard way

if your going to tear the motor down n do all that, id definately try to get the 350... rather go internal on a 350 than a 305, since with a 350, you have a larger bore, and more cylinder head options in the furure, able to get bigger valves, etc, plus youll overall be making more power with 45 extra cubes..

if you dont have emissions, or just know the right ppl in that field hehe, then i would go 4bbl carb, and forget fuel injection. that way you could slap a carb on, ditch your computer and associated wires and sensors, and be done with it. i know that a lot more experienced people can get into more specifics once you are set on an induction system, and i remember reading my search results on the topics for hours when i was home sick from school a while back, and got a good background that made me comfortable with attempting the swap later on..

hope that helped a lil bit, but as i said, more experienced people could go into more depth than my lil azz lol

 

ok well, i now have info on some changes that i need to make

my uncle was telling me that i will have to get a special intake. but what about the head. can those be from what ever after i get the intake or would those not go onto the block easy. like the bolt pattern is different. is this true.

second i hear everyone saying to switch to carb. ok i got it i got a holley 4bbl. now, where can i get the intake to go on to that block? if anyone knows let me in on that secret.

what kinda of junk could i get a tranny out of to go to this v-8?

ok well enough questions, im sure ill have more later

 

depending on the year of the motor, forces your intake selection. V8 motors 87+ have a different intake bolt pattern, different angle the bolts screw into the heads. so if you get say an 89 350 out of a truck for example, you can save money and port the heads and have bigger valves installed, and get an 87+ intake to mate up to it. the 87+s have centerbolt heads im pretty sure... i cant remember the cutoff year for some reason i remember 87s having centerbolts, but by 88 they all had them i know that..

if you choose aftermarket heads, they will give you an option sometimes, whether you want 87+ intake bolting, or the older 86- intake bolting, so depending on the heads you get, determines the intake you get.

as long as its a squarebore carb intake manifold, and not a spreadbore, it will fit the holley. what cfm is the carb?

once you decide on intake and heads, you can go to jegs or summit and have a field day picking from intakes lol
