alright...

in not claiming to be a hotrodder by any means... so i have pretty much no clue about anything when it comes to that, but it seems that you guys know your engines bigtime!!!


i own an older nissan and want to make it more crawling/bogging friendly, and the lil 4 banger just isnt doing it for me... from what ive read, the straight 6 sounds good in the low r's.
i can get my hands on an old f150 w/ a straight 6 for free. my uncle says its a "300" i think its a '79 or something close im pretty sure it has a 4 sp tran too. Im also going try to swap a straight axle up front, so the motor height is no issue( at first i was worried about the oil pan interfering w/ fron diff, because the nissans have IFS), i plan on having to do allot of fab work, but thats what im going to school for is machining and welding.. so what better time than now...


now about the motor
first... is it even worth it?? i couldnt find much in the archives here about the 300 out of the late 70's f150's
how buildable are these?? can i get mods for these like any other straight 6?
i know the carb is trouble, thats why im getting it for free.. i have no clue where to start for carbs.. is it true that holleys are built more for chev and edelbrock is more for ford or vice versa??

will that motor turn out so much more power that itll rip the nissan driveline apart? will i have to swap the whole ford rolling chassis.... minus the frame.. and front sus, its a 2wd ford so i will have to get the front axle elsewhere.

any help is appreciated in making my first step to gathering parts to build theis motor.

Wow what a killer buildup,the straight six engines are awsome torque engines due to the inline six design(less friction).the six will get resonable milage too compared to an eight and since it a four wheel drive chassis it should hold up to the torque,as long as your not doin reverse firsts lol.My question is can you fit an engine that long into that engine bay?As far as the carbs doesnt matter what engine its on as long as its tuned youll be fine.As far as aftermarket parts you could probably find headers no problem and if it doesnt have a fourbarrel intake hell you can make one of those like ya said nows the time.Sure would make an excellent crawler

I'm not much on the straight 6's. but at this place there is a forum on the inline's..... my bro inlaw just bought a 75 with a 300. looks like i'll be getting familiar myself.....

[Quarter mile killer]

inline 6's were never looked upon much because it just does not
pack the punch of a V-8. An I-6 is a excellent all around driver
and has great dependibility and a considerably much better
MPG then a V-8 although it never was meant for a strait line.

are you gonna swap the I6 for smc v8, larry or are you gonna
restore it to original condition for show.

ya, im pretty sure the fire wall will have to be pushed back a little bit... ok meby allot lol. but thats alright. itll be just that much more oiriginal... im thinking of just scrapping the whole plastic dash thing and making a "custom" sheetmetal one for all the bajillion gauges and switches and bells and whistles i plan on putting in there.... so it sounds like this 6 might be a little bit of a goldmine for me... especially sice its free.

I think you will run into clearance problems with this swap because the 300 is a long engine.

Years ago I blew the 200 I6 in a Ford Maverick and a friend gave me a 300 complete with bellhousing and fly wheel to put in my Maverick. When we went to put it in we found that the engine was just too long for the space. I ended up putting a 289 V8 in it.

I think you will run into the same problem with your Nissan.

To cut costs, many of the internal parts are shared with the V8 (windsor).

so where should i begin looking for parts to build the 300?
website suggestions? catalogs i should know about? what name brand parts to look for?
what parts are more important to replace than others?
put new pistons in right away??
i want to to this thing right.

Some forums to check out:

Ford Six Performance

Ford-trucks.com Inline-6 forum

These people really know their stuff with the I6 engines. They'd be the ones to talk to. Hope this helps...good luck!

[spooki]

Quarter mile killer.............it was my I-6 300 larry was talking about.
it will be a while before i rebuild it. but i think im going to bring it up to the HD version when i do.

for show.............why would i do something like that.

[mikeweyman]

these engines are quite common, i had one in my 82 f100 pickup.
it wasnt a barn burner, but i couldnt put enough dirt in the back to stall it. the carbs arent really a problem, its the stack pipe from the intake to the exhaust manifold. without this , the carb freezes and can cause much inconvenience, though little damage.i dont think you will get this mounted in the nissan though,its way too long. i dont think you are allowed to mess with the firewall. it would be a shame to have it junked by the transport people after such a job well done.why not a 2.9 v 6 or something that will fit. sometimes free parts should be given to someone who needs them.

[aceshigh505]

the thing ive heard about WI is that they dont check your cars... like in other states... ,neither i or any of my family have had their cars "checked out"so if i were to mess with the firewall.. who would know.. or care..
if i had the money for a V then i would.. but ive got to go with what i already have in front of me... money is tight and i have to cram all the fabricating in now while im in school and have access to many machines.. unless.. of course you have a V you wouldnt mind donating
