Tom's 61 Impala

WOW!

The whole car looks GREAT, the engine is just. holy smokes! NICELY DONE man! two-thumbs-up-smiley-emoticon

Very nice! The next one, what sort of motor was in it that you plan to add as the real one?

Tom,
Thats OK, I misunderstood what you had typed, thats my fault, (After I went back and re-read what you posted)....

The 348, how'd that run, with the "W" heads? I've heard conflicting things on them and same goes for the 409 as it was built much the same way as the 348.....Impressive to look at none-the-less!

GREAT model of the real one, NICELY detailed engine too! Interior with a closer look, was done GREAT too!

You mentioned an Olds............ OHHH BOY!!!!! I can see a 455 coming soon!

Smooth paint and gorgeous engine! Really nice!

Bigger then a 455? big-drooling-smiley-emoticon

I wait to see or HEAR of the plan for engine size LOL (right its all about "plastic Horsepower" right?

It was a big car, the Impala was, but the 348 wasn't no slouch either! That "W" head engine was a monster puller when you stepped on the gas pedal a bit heavier it didn't take no time to respond to the fuel going into it.....

I've worked on the ole 409's in the past, but never got my hands dirty on a 348, even tho they're pretty much the same engine just different bore I think....They may have made a longer stroke for the 409 too, BUT I'm not sure on that one! I know the bore was different between the 2

Yea it was a fun car.. When you really laid into the Gas pedal it would pull good all while hearing the three carbs sucking up the fuel..Mine was the 350 Horse version.Tri Power , Solid Lifter Cam, 4spd..
I did buy it used , was probably traded for a Goat or some other Muscle car in 1965 when I bought it.
Had to do a lot of talking to my Dad to get him to co-sign for me,but he did..I guess the fact he never removed the Air Cleaner (showing the Trips) helped, plus the linkage was miss adjusted ( or maybe on purpose ? ) not allowing the carbs to open fully, and the solids were not adjusted correctly.
      Naturally being the young Gear head I was , I found out these ( easily fixable ) problems and corrected real soon after I took possession of it. After which it ran  WHOLE LOTS BETTER ! !

    As far as the Plastic Horsepower- A 454 Chevy  /  30 over is a 468 . The Olds Block  is pretty beefy on  the bottom end, so boring 60 over or more is possable along with a different stroke crank would kick up the Cubic Inch. Don't remember the formula for figuring out cubic inches, but I think it some thing like Bore x Stroke ?? So  ( Plastic ) cubic inches of model Don't really count in Plastic but I guess it is Plastic Bragging right's...L O L

Beautiful! Love the engine and engine bay!

I myself will WAIT to hear what your building. As with the "Plastic Horsepower" comment I have whats called "DEsk Top Dyno, andcan get you what the engine size is, IF you have the bore, and the stroke, and then tell me what the "overbore" was done.....I then can give you EXACT C.I.D. of the engine that your building.....I use it a lot at times with my step son as hes always "messing" with engines in real life, I got his factory stoke 5.7 Hemi putting out over 450 HP right now and ALL I done to date, was adjust a few screws and timing on the engine, if he went and got a MSD ignition, and hotter plugs, I bet he could take that engine WELL OVER 500 horse! AND with its current settings, he's getting like 12 to 16 MPGS.....where before I done anything he was getting something like 16 to 18 MPGS....SO, he didn't loose much in that way!

As far as plastic, sure its braggin rights, I'm always making something like that it seems! (In my years as youth), I LOVED big powerful PRO-stock cars, now I'm finding with age and knowledge and just a hint of appreciation, I'm liking bare "stock" these days... Got to love the old Stock versions, if it weren't for them the "mods" wouldn't exist, right?

But its all play right? Always fun messing with stuff in plastic, (IF I had the money and space), I'd be doin it to real cars LOL

EDIT:
Correction:

I took the 454 info you gave me and punched it into my Desktop Dyno, and this is what it comes up with:

Bore = 4.28
Stroke = 4.00
Over Bore = .030
Over Stroke =0.00
Cylinders = 8
Cubic Inches = 460.391606924154
Liters = 7.54455872251699

That would be a 460, 7.5 Liter As none of the infor AFTER the "." is .5 or above.....

Interesting, you know how you came up with the 468 CID?

As for the Olds motor you plan to use in your model, what size is it? and then I'll let ya know what I come up with as far as what it be all "beefed" up and bored and even stroked.....
 

Tom,
(If I remember your name correctly excuse me if thats not right)

Anyway to get C.I.D. you need to do this:

("Bore X Bore" / 4) X pi X Stroke X # of Cylinders.

So, me liking The 425 Hemi, I'll use its info....

("4.25 X 4.25" / 4) X 3.141592654 X 3.75 X 8 = 425.59, or 426 cubic inches Which is a 7.0 Liter engine!

So, take the info I gave you for the 454, and punch it into my Desktop Dyno and it comes out to:

Bore = 4.31
Stroke = 4
Over Bore = .060
Over Stroke =
Cylinders = 8
Cubic Inches = 466.868314338795
Liters = 7.65069423559633

Which still only gives a "467" BUT, he would have been close, AS the crank if it was a stock one and "ground" to polished tolerance, it would have made it a slightly bit more to get the "468" that he mentioned to you. Also, a good over done "Honing" to each cylinder to remove scratches, and or scars, so that could gain the 1 cubic inches over the span of 8 cylinders, BUT, thats even questionable.....

.060 overbore seems a bit much for a "wedge" type engine, BUT, thats not say that used factory 454 either! He could have used a "Crate" 454 which if my memory serves me right, they offered crate 454's that were LS-7's instead of the stock LS-6, that were Siamese bored blocks which would have gave the possibility to be overbored much more then a stock 454......

However with a bit further research, could have it been more possible to he had used a Pontiac 455? I punched that in! Here's the results:

Bore = 4.37
Stroke = 3.9
Over Bore = .060
Over Stroke =
Cylinders = 8
Cubic Inches = 467.958509821443
Litres = 7.66855955658429

This would have been classified a a "468"....

Your friend with a special crank in a 454....can ya get me the stroke he used for the crank? AND while yer at it, with him ask him if he knows what the bore is, or was and what he might have had it over bored to get correct numbers!

As far as one liter is 61.0237 cubic inch.

The 7 liter engine covers a FEW! Mopar was the first and smallest C.I.D 426, Chevy 427, 428, Ford 428 and 429 ALL Hemi, or Wedge combustion chambered engines were ALL "7.0" liter.... Remember in the engine classification, the cubic inch AND cubic liter sizes was never including the "Combustion Chamber" into the "size", metric or SAE....Simply put, a rounded up from .5 to the next number. Make sense? Which sort of included the combustion chamber in the rounding up of the number, IF the number was below .5, they left it, as that number. NO rounding up.

Hope this helps!

Tom,
You fool LOL you got me thinkin I WAS STILL workin in the ole Garage I used to do all sort of Mopar builds in, (BACK, then however I didn't have a computer to play with!) LOL Those were the days tho when ya HAD to use yer own head and what ya were doing.....

So, opening "Desktop Dyno" lets see what we have shall ye?

Bore = 4.411
Stroke = 4.25
Over Bore = .060
Over Stroke =
Cylinders = 8
Cubic Inches = 519.568620638154
Liters = 8.51430805824286

CRAP, that is close, what formula did you use? See, with my Desktop Dyno, I don't have to "add in" the overbore, there is a place for the "Bore" and then the "Stroke" and just below that you have "OverBore" and then followed by "OverStroke", then followed by #of cylinders.....

So I ask ya, whats the difference from the 403 block to the 455 block as far as "bore" size? I ask as the 455 bore might be able to take a .060 overbore, with a 403 crank (shorter stroke?), making a long stroke increases cubic inches.....I'm sort of familiar with the 455, but I am not familiar to the 403......?

So I took the 403 stroke, came up with this:

Bore = 4.411
Stroke = 3.375
Over Bore = .060
Over Stroke =
Cylinders = 8
Cubic Inches = 412.598610506769
Liters = 6.7613622815458

Sadly with this one under the computer it gets a much higher compression ratio! AND that enable it to be NOS squirted! Bring the piston out of the hole up into the combustion chamber much like a high compression Hemi, and you got 14:1 compression! WHOA! Max RPM shown is 6,800 redline! Was always said that Olds came close to Mopar with the Wedge Head to the Hemi Head, and gawd, they were right, Never done the math years ago, but on the computer WOW! WHY did GM just toss "Olds" away!?

Question Tom, you familiar with the Olds "455" Pent-Roof Hemi as they called it? This engine my friend was a MEAN Olds "Blue" fighting machine.....GM tossed in the scrap heap! After it wasn't possible to be made "legal" with omissions! back in I think I read '72......

Ohhh yeah, BTW, call me John......

And yes, this is a BLAST! Seriously....(I bet some are going OK WTH are these 2 chatting about LOL) Its all good man! I haven't even got into valve sizes yet LMAO

Very Nice, Clean Build! Lots of detail too. Looks Great!
