some people just shouldnt talk

[bigjohnson4.6gt]

well then i guess i stand corrected, i did not know you could do that, could you just bolt up a set of 4 valve heads?

 

[tooslow]

yes.

but when you do any swap you also need the correct timing cover.

i also think the 4v swap requires the use of the cobra computer. the 3v swap can be done with the 2v computer if you know what/how to disable the correct stuff.

 

[phil_the_thrill]

yeah thats whose car i was going to mention was 3v2000GT's. its a pretty nice car makin good power

 

[scarface]

many people have done the 3V swap and it will makes around or as much power as a 4V would. not everyone knows everything, you just met someone that knows something you don't

BURN! He's right though, the 3-valve swap has been done and does make great power. Sorry to break it to you, but he knew more about modular Mustangs than you do.

The '73 Mustang? Horribly slow and perhaps one of the most disproportioned vehicles ever built...

MAKE IT GO AWAY PLEASE GOD MAKE IT GO AWAY!!! IM BLIND!!!! :slap:

I actually had one of those...lol had a 351 Cleveland in it..

 

[Downshift]

It wouldnt be bad except it looks like a door stop. If the back end was a little more subtle then sure. Probably could smoke my car anyway haha. Thats ugly though.

 

[bigjohnson4.6gt]

looks like a mustang wagon

when i was first getting into stangs those were my favorites 71-73 mach 1's ...growing up one of my uncles had a 72 and the other uncle had a 73 so i always had a thing for them...now i look at them more and more and go um..... the best part is trying to look out the rear window and trying to see anything hahaha...i still think the worst stangs are 74-78 and a very close second is 79-86.... they just totally dont appeal to me i was worried the must was lost forever and i got to say the aero nosed stangs 87-93 really didn't get my blood rushing either but it was better and i stupidly bought one :nonono:

LOL tRaV_19... My favorite Stangs are the 4 eyes LMAO

My uncle had a 72 Mach 1. That thing was NASTY. Those 351 Cleveland's with the 2 bbl carb heads just went sick fast. The 4bbl carb heads valves were just to big and did not work at all down low. They had to much flow, kinda like our "B" head Cobra's.

 

[rick focks]

i wouldn't want something that big w/out a bigblock init

Or a fog horn. Don't worry, I think you need a CDL to drive one anyways.

Did they have different heads depending on which carb was used?

I'm pretty sure more head flow at any place in the RPM range is a good thing. There will never be a thing as "too much flow" Just too little engine...haha ;D

 

[trav_19]

71 mach 1's could get a 429 in them O0

351 cleveland is a big block. isnt it ???

now thats just opening a can of worms on whether or not the 335 series motors (351m,c and 400) are small blocks or big blocks. They have a big block housing yes but does that make them a big block... i say no.There are many other debates on what makes it a small block or a big block. So i say just call em "middle blocks" and call it good ;D They are underestimated motors that is for sure. Small block and big block are chevy terms anyways

yeah, after I originally posted I researched, and came up with that info too... thats why I edited it with the "isnt it?"

 

[MeanGrn Gt]

ok gotcha... now ya wanna have a discussion about what the "m" in 351m stands for??

 

[Shocker98GT]

71-73 Mustangs were boat anchors compared to the models before them. Not to mention the aesthetics uke: Torinos of that year were much better looking (and not a lot heavier)

The Boss 351 was a flat out beast for it's day, though. 2V Clevelands were better for the street, though. But there's no denying that the Cleveland was the best "smallblock" V8 of that era, maybe even ever. Or you could consider it an intermediate block but displacement wise I'd categorize it a small block. It definately had substantially more potential than anything GM or Chrysler put out aside from the LSx series.

I think Ford should call their rumored new engine series the Cleveland, especially if they keep it SOHC. It's supposed to be built in the Cleveland plant AND you could have 2V, 3V, and 4V versions (except the V would stand for valves instead of venturi this time). An interesting twist on nostalgia :naughty:

 

[Shocker98GT]

I heard a Camaro owner sitting around talking in an auto parts shop to a buddy about a month ago. He was saying how he just put LS1 heads on his LT1 car :rollinglaugh: I smiled and asked if he'd changed the headers and intake yet to "match the extra flow potential", he's like "naw, running the stock stuff for now until I save my money up for some really good stuff like an Elderbrock (that's how he said it) intake and some good exhaust" I was like it must've been tough making the siamese port headers and intake match those LS1 heads :hammer:
