That seem's to be the Only motor people are putting in these things. Just wondering if anyone has used anything else.

I'm personally planning out a 4.6 DOHC aluminum block ford motor. Simular to a cobra Motor. I'd like to twin turbo it and make around 650 rwhp. I just don't know how hard it's going to be to put the wider motor in with the turbo's.

Does anyone know of a DOHC V8 in a FD? I'd like to see pics of one to get an Idea of how cramped it is.

I'm thinking there may be room for the turbo's either under the heads or in front of the motor.

Later,

4.6 wont fit, its way to wide

 

ive considered using a mopar 383 bored out in an fc. i think it will fit, and parts seem to be easy to find.

 

AN LS1 barely fits. There's no way any modular motor is fitting without some serious trimming. You might as well strap a solid fuel rocket to the car, because they're going to fit about as well as that 4.6

 

Why go with a motor that weighs more, has more rotating mass placed higher, less displacement, and less power? Because DOHC is "more efficient and advanced"? The LS1 is the first choice for many reasons.

 

Bill Hagen (formerly), John Pham, Bob Kelly, and I all have LT1s. Kurt Williams has one of my cradles but is apparently going to use an SBC derivative instead.

The average LT1 weighs a bit more than the LS1 (about 60 lbs. in full trim, including cast iron exhaust manifolds), but it sits a few inches farther back in the car, thanks to the clearance at the back of the intake.

 

would a 383 with a 727 (i think thats the model) trans fit ok?

 

Find out what the dimensions are and then compare them to the known combinations, and you'll have a ballpark answer.

 

I loved my toyota tundra, (4.7 DOHC). There's been a couple of times driving my FD that I wondered if a lexus v-8 would fit.

there is a list of engine dimensions.

D Height from bottom of sumt to highest point on intake manifold
E Height from bottom of sump to top of Carburetor
F Length from rear mounting surface to water pump pulley
G Length from rear of intake manifold to water pump pulley

 

is the chevy v8 a tight fit in the fc? from the picturs ive seen it looks like you have a little more room to play with.

 

The Ford 5.0 and Chevy LT1 are about the most compact small blocks you're going to find.

For reference, the LT1 is about 24" x 24.75" x 27.5" (H x W x L), which corresponds to "D", "B", and "F" in your list above. In other words, the Mopar is considerably larger.

The LS1 is a pretty tight fit in an FC or FD, and is approximately 25" x 26" x 28".

 

The 383 is not a good swap motor, considering you can now build a 426(or larger) LA small block with a cheapo stroker crank from MP, its a smaller engine externally, with less rotating mass....The only benefit is 383's are cheap, and they have large stock valves for thier displacement(same valve size as 440).. But the only B engine worth building is a 400 with a 440 crank=451"...
The best small block budget build I can think of is a early 70's 360 block with cast stroker crank , use late model magnum heads, and intake manifold(mpfi), add stand alone, the MP head porting kit, excpet for a new cam, pistons(rings) and headers, the entire thing could be junkyard built and be a pretty potent package.. So far the Mopar block can be built into the largest small block of all the big 3 at this point I think, mopar has always had to much deck hieght for its displacment..max

La small block..

World Products sells Motown 454 SBC crate motors, the LS1 can be taken to 454, the Olds Rocket block can go 46x, and Shafiroff Racing now makes a 472 CID SBC based on a Dart block.

 

Let me clarify that..... On a prouction block, non ohc engine, and with a sane rod ratio....Max

 

So in other words, anything you can think of that might favor a Mopar?

 

you bet...haha....Of the average big 3 typical small blocks, the mopar has alot of internal measurements that make it more favourable to large cid stroking on production based components, also without siamesed cylinders...
The deck hieght is the highest of the "popular" small blocks, they have the longest rods, the cam is well up and out of the way for 4"+ strokes, this echo's up to the RB mopars as well, they really are to large for what they displace as stock blocks, and make for perfect strokers.. For the average person contemplating the v-8 swap, I think they are doing it to find large power ,without spending alot of money, which rules out alot of semi exotic small block packages, which is why I point out how easy it is to crank up the mopar in a big way, should I do a v-8 car in the future, I know I could do 400 rwhp for pocket change pretty easily, from 85% junk yard parts...
When you look at the pontiacs and stuff their small blocks have large deck hieghts as well, but in the case of engines like that , its easier to just drop in a 455 than dick around stroking the smaller displacement engines of essentially the same exterior architecture..
Mopar has done alot of work on the small block with the nascar programs, they make the stroker cranks with 2 bolt patters, chevy and mopar, so transmission hookup ins't an issue anymore, it used to be impossible to link up a mopar to a car friendly 5 speed, but the crank pattern option, makes it much easier.. Alot of people overlook the mopar, its a shame really, lots of potential for little money..Max

 

well i have a 318 (i think its a 318) and i think a 927 and a 383 with a 727 out of a 68 dodge monaco at my disposal pretty much. and i like mopar so if its at all feasable then id like to go that route..

and max since you seem to be a mopar man (i really do like mopar, i dont know why but i do) any links would be appreciated or advice is always welcome.

 

Google is your best bet for the mopar stuff, Mcandless was always one of my favourite..
yeah my mopar blood is alot deeper than my mazda blood, I have built alot of small block mopars of the years, and even a strong 318 that I drag'ed when I was a teen...Currently I own a couple of big block trucks, which I still play with..
The auto you have with the 318 is a 904, nice small short shaft tranny but not that strong, grab a 4 speed auto from a truck with msd speed switch for lockup.. You can get a 360 from most U pull it junk yards 75 bucks, the earlier the better.. if you budget build the 360, get a piston that will give you zero deck hieght, the problems with alot of dodges, is the pistons are 3 miles down the hole at TDC, which means really low compression, a nice set of even cast aftermarket cheapies can fix that...Max

 

thanks. so i should go with the 318 and bore it out or just find a 360 and do it that way(what about the 383)?
which has more potential? and do these blocks hold boost good?

 

yeah just find a 360, same external size and wieght, but already 42 cid bigger...Then stroke it for ***** and giggles..

Sell the 383, someone might need a 68 date coded block for a resto and pay some ridiculous amount of money for it, same with the tranny....The only really decent part of the 383 is the heads if it was a 4bbl motor , it will hav the 906's probably on it..max

 

grannys speedshop has a 318/340/360 conversion kit. i may look into that. will the 727 trans bolt up to the 318/340/360 motor?

 

jim has a writeup on that shop , i believe?

 

he does. ive heard iffy things about them so im gonna try and avoid them.

 

watchin out for my hometown fellas
