goodwrench replacement 350

go to paceparts.com

and check out this engine

its a 4 bolt main
and makes something like 250 HP

a nice mild engine for my swap

and cheap too

would that engine's stock bottom end handle a little more power

per say an edelbrock intake, headers, aggresive cam????

if so i have found the motor for my swap

then i can go mustang killin

It is indeed a mild engine. I have one in my full size '84 Chevy van that we use to tow the horse trailer.

The bottom end can handle more power. But, with dished pistons and small valve/port heads, it is pretty limited. And, "aggressive" cam is where you need to depart from your dream.

Put it in, come on out, and we'll see how it stacks up against my 305...

thanx five7

yeah i guess i'll prolly get it then

cuz i can always bolt some new heads on there....... not to worried about the bottom end cuz i only plan on doing so much

is it a one or two piece rear main seal???

hmmmmm i guess i should really keep my options open though because i am going to be starting my internship at a GM dealer in a few weeks

that means i will be able to get parts at $10 over cost

so.........i will take a look at the more powerful engines too

Note this under the picture: "*Fits carbureted vehicles up to 1985". That tells you it's a two-piece rear main seal.

You might consider getting a 350 shortblock instead, put World S/R Torquer 67cc or Sportsman II heads on it, a nice cam (now you can talk aggressive) in it. It'll probably not cost you a lot more than that complete universal replacement engine, and would have a lot more power.

Do you have to go through emissions testing/inspection? If so, you are stuck with TBI or TPI for induction.

if you have the money i would DEFINITELY go for a more powerful engine. possibly a GM crate engine. for the little added cost ( a few hundred bucks..maybe a little more) you will be WAY happier with it. also you will have a LOT more potential.

just my $.02.

i am going to take your advice

they sell a 350 for about $2000 i think
i'll probably get that one

only thing is it says for pre 1975, so does that mean i cant use HEI????

also, i havent gotten to my igition class in school, what do i need exactly for a HEI ignition system? just a coil and a compatible distributor?
and how do i hook up my carb??
what kinda carb will be best??
and what do i do with my vacuum thingies??

after the engine swap a T56 will go in next

Depending on whether you can install the heads and cam yourself. You might consider a brand new L98 shortblock from Scoggin Dickey for $1200 and put on the heads and cam recommendation already made. That would make a nice reliable starting point.

The pre-1975 thing has to do with emissions, not the ignition. I've had an HEI in my '57, the newest engine it ever had was a '72. I'm going to put one in the '66 engine for next season (small blocks and big blocks can use the same distributor, if you can believe that).

You can use a non-CC q-jet, Holley, Edelbrock, or Demon (what I wish I would have gotten for the 396). For primarily street driving, the q-jet is best.

There are a bunch of posts about converting from FI to carb on this and the carb forums. Check them out, ask again if you don't understand.

Before you get too far, you might want to rethink your "connections" approach to emissions. Both of your net worths can go down pulling that stuff. Why not just stick with the later technology and upgrade your TPI?

uhhhhh no offense, but lets not get on that subject

all thats matters is that emissions dont matter


now, i am thinking about getting a digital dash that hookups to the stock sending units
(nordskog from summit)i am figuring that the speedo is run off the computer from the connection on the tranny, so my question is whether my gauges will work when i take away my fuel injection system???

i am planning on getting rid of my a/c
so i am not concerned about that

my other question is where do i hook my distrbutor's connections to? i havent gotten this far in school yet
i think i will go with a HEI ignition........

and then i guess i run my fuel lines into an adjustable fuel pressure regulator and set that to 5 and then run the fuel from there into the carb (am i right?)

and i also am assuming that i can connect my current throttle cable to the carb??

now i just gotta figure out where all my grounds will go..............

and where can i get the pipe to hook up my PCV vavle?? and where does the other end of that pipe go to??? (the carb?)

i know how i am going to hook-up my electric fan........

will my stock y-pipe fit the headers i will be getting?? or will a trip to the exhaust shop be nessacerry?

how do i hookup my ammeter, oil pressure and coolant temp gauges?

the questions go on and on but i really want to do this swap

and i even found a crate motor for $3000 that is 330 HP and includes the distib., water pump, carb and intake manifold............
