351 fox?

[81elky350]

I don't know exactly where to post this:
I was out looking at my '84 Bronco the other day, thinking how tragic it was to sell it just cause of cracked heads. That's when I noticed my friend's 91 LX. Then I got an Idea...
So I was wondering what all I would have to do to throw the 351 in a fox. Is a 351 too heavy for the stock fox body? Please help...

headers ,oil pan, hood,other stuff depends on if your going fuel injected or carb,it will bolt up to a 5 speed not sure about the auto.here's my 408

 

[81elky350]

Yeah, I was thinking a four-eyed fox, so carbureted. My friend's got an '84 (?) with a 5 speed, and he's considering selling it to me for $100. By the way, Nice motor(that fuel rail is huge!)... Looks alot nicer than mine...for now hehehe

i was gonna carb it but,i like the fuel injection,its pretty easy to tune and i suck with carbs.lol. carbs do make for a cleaner engine compartment.

 

[81elky350]

Fuel Injection definitely DOES have benefits, but I just love that old 4-barrel rumble. HOLY COW MY SMOKE DETECTOR JUST WENT OFF!!! Anyways, I guess that 408 probably rumbles enough, but I'm still on a High School Budget .But I do have a 460 sitting in our work truck...

It's not the carb that makes the engine rumble...you can get that with an EFI set up no problem, lol.

Anyway, check out the thread in my sig and I have progress pics of pretty well my whole 408 build/swap in to a 4 cylinder car. I highly recommend doing it.

 

[408gt91]

ive seen that thread looks great,how do you like the four gears of rubber?lol.

 

[BlooDReigN]

Ummm. I don't, lol. I wish I could hook up!!

I just need some slicks though and all will be well. I hope to make a good pass with sticky tires this friday. We'll see what happens!

 

[408gt91]

let me know how you did.

408gt, very nice setup. I had (crying over selling) a 90 lx with a carbed 418, TFS"R" head headed ect............. Have you run your car at the track? Dynoed? Mine made 583/546 on the engine dyno. With a 5spd and a weight of 3300 with driver, on a short shifted shakedown pass with drag radials the car went [email protected]. I was very happy with that. I put a C4 in it and never ran it again, would have hoped it might have touched in the 10's.

 

[408gt91]

this is my third fox with the 408 combo,i have'nt run it at the track or dyno'ed yet,im still waiting on my hood.lol im looking for somewhere around 550.what size cam did you use?i used a comp 575/595 lift.im sure ill be sucking hondas up through the intake.lol

 

[5.0 HOtrain]

It was a custom hydro roller from comp, I believe it was 252/[email protected], 110 ls, .576/.576 lift. Went with the crane drop in like bar lifters, no valve float @6800, made peak @6500.

Im gonna break it in on the 30lb injectors then recalibrate my mass air for my 42lbs.its gonna be hard to baby it.lol

WOW way to derail this thread guys. The 351 should fit because its the same block as the 302, but i cant be too sure about how it will fit up to the transmission. But yet again if its the same block i think the tranny will hook right up.

 

[408gt91]

accually the block is taller.

 

[DemonGT]

mmmm yea, 302 block isnt the same block as a 351....

pretty much all the accessorys from the 302 will bolt to the 351 along with the tranny...so most of the 302 stuff WILL swap over to the 351 but they arnt the same blocks....

thought it was taller AND wider?
