Default New coupe

hello, I just bought a coupe.
This will be delivered next year.
Now I'm already getting some preparations, which engine, what wheels ....
I plan to drive a lot of kilometers a year.
The engine selection is either a 351 stroke or a coyote.
what do you think of it?

Greetings

Which coupe? FFR, Superformance, Shelby, Kirkham, other?

While the Coyote really appeals to me, I'd be concerned about how it would encroach on footwell space. I'm 6'3", with size 11 feet, and if I were building a coupe I'd most likely go with a stroked 351W - mostly for space, but also partially for appearance. A 427W or a 460W with an 8 stack EFI system would look so sweet and would supply more than sufficient power.

A coyote with a borla 8 stack is also sweet

In my cobra I now have a semi-race block, and when I get to a crossroads or a traffic light, the engine starts to shock at low speed.(the buck)
In my next car I want to avoid this, so I thought of a coyote. Also, the fact that there is a rev limiter on it makes me think my valve springs will stay alive.
if a 351 is stroked to a 408 do you have the shock problem then?
The 351 is less work like a coyote in any case.

Why are you compelled to put such a large engine in the coupe? The originals had the 289.

That low speed bucking can be caused by a lot of things. Could be something simple like incorrect ignition timing. Or a rotating assembly that's too light. You can get that from any engine, depending on how it's built, and the drive line behind it.

The Coyote is a huge engine. It's a lot wider than the Windsor engines. Getting it to fit in a car not specifically designed for it can sometime be a challenge. But it is a great engine. If the car you purchased is set up for the Coyote, consider installing it. It's a great engine for such a small displacement.

If the car is not set up for the Coyote, I wouldn't try to adapt it. It's a lot more work than you might think it is. Lots of cutting and fabrication involved. If you can easily do that kind of work, great. If not.......

First, what's the budjet ?

Second, how about a FE ?
A 390/445ci is a engine I was thinking of.

Or maybe a 385 series ?

This time with my engine, I thought of a 385 series like a 460, stroked to maybe a 514. Gobbbbs of power and pretty cheap. But, I found a new 428FE a couple of weeks ago.

Remember, a large cube small block has to work very hard, to get the same power of most big blocks. The 351/427ci sbf is real popular.

If you're still thinking of the Coyote, this video may confirm your decision !

I have used the 351 stroked to 418, 410, and 408 in my cars and I now have a 408 stroker in the Coupe. I had this engine built to lower the power as I no longer race and I can run this one on what they laughingly call pump gas in this state. It still puts out right at 500/510 horse and that is more than enough for what I do now.

It would also help if you stated where you are. US would allow all of those, but Australia from what I understand would almost force you to the Coyote.

That said, if your car is a new Superformance etc, a Coyote will certainly make it harder to sell in the future. Most buyers want a period correct power train in a Cobra or Coupe.

A lot,....of Superformance come out of the factory with the 365 series, most are 460's.

I don't plan on ever selling my Cobra, unless my health gets worse, but if I do mine will sell better as a FE will be in the car. The 351 engine is very popular, but even they won't bring the money. If that doesn't matter, put in a Hemi or a twin turbo Diesel to be different ! lol

(Ron, I'm going to send you a message about your 8 stack)

Unless I'm missing something, cubic inches are cubic inches. a large displacement small block shouldn't have to "work any harder" than a big block of the same displacement.

Some data:
  • FE (15 examples): 0.97 - 1.50 HP/CID, 1.08 - 1.32 ft-lbs/CID
  • Windsor (425 CID+, 4 examples): 1.14 - 1.49 HP/CID, 1.18 - 1.32 ft-lbs/CID

Worth noting from Brent's data is the top Windsor (445W, 1.49 HP/CID) was running less compression (10.7.1 vs 12:1) and less cam (0.700"/0.690" lift vs 0.760"/0.760") than the top FE (465 CID, 1.50 HP/CID).

There are no material differences, cubic inch for cubic inch.

Hey,
Because I live in Europe, I thought of a coyote engine.
There are already very low emission zones in the big cities.
And as it looks now, there are many more to come.
On the other hand, there is little pleasure in driving in big cities, cities in general.
Indeed, the resale value will be lower, but I plan to enjoy it for a long time so I'm not awake about the resale value.

The view of the coupe I want to approach as well as possible.
I like the old scool look of the coupe so an old block looks fantastic.
certainly with aight stacks.
decisions, decisions, ....

Greetings

Hey Ron,
Are there any disadvantages of a 408 versus a 351?
How is consumption, ratio 351 versus a 408?
This is going to be my wet weather car, so 500 hp will be more than enough.
Do you also have a tremec tko or have a different gearbox.

Hey Kevin,
A FE out of the question.
In my opinion, he is too heavy.
And too much maintenance.
The weight distribution must be correct if you want to take turns. (But you know all about that)

If I were still road racing, I'd have a 427 small block.
If I were still drag racing, I'd have a big block FE.
If I were still having fun on the street, I'd have a FE. But wait, I still have both !

I agree, you may enjoy a small block more. Check out Brent's new sm. block video. 600 HP.
I don't, agree with the FE maintenance ?

For you 351C fans....turn up the volume!!!

Sorry that I took so long to answer but I have been pretty busy working on our site lately. I really don't see any disadvantages to the 408 versus a 351 at all. I went with the smaller stroke because of longevity. When you push any engine to its max, a 427 from a 351 for example you are more prone to breakage and problems. I have a friend who has a slightly hopped up 351 in his Cobra and he is very unhappy with it as he wants more power, but to me for what he does that is the most sane car around here. As for consumption ratio, he doesn't get much better mileage than I do and none of these cars get great mileage.

Rons engine is a nice solidly built, nothing radical motor. It should outlast Ron, (actually I don't want to see either one of them blow up). I have a few videos of his engine going together and other than it being an all roller EFI 8 stack injected and tuned to a fine edge , it's just your run of the mill Ford engine. BTW, Rons gear box is a stock out of the crate TKO 600. It was a bit notchy to start but should have smoothed up by now if he has enough miles on it.

Thanks for the comments,

It's clear to me that I'm going to go for the old scool engine.
And indeed do not try to get the max out of 351.
In my current cobra there is a tko 500 and it works perfectly.
This time it will be a tremec tko 600.(less rpm’s on the highway)

hopefully you can help me with the wheels too.

I have seen fia rims but these are only available in 15 "
These are the most beautiful for a coupe, but I would like 18 ".
Then I have the best of the two worlds, handsome rims and modern tires

I will try to post a link from the rims.

Greetings
