FE ONLY OR 514ci. CRATE IN YOUR,....COBRA ?

[Dimis]

If I had a pretend cobra, with parts already set up for an FE, and could get 350-400 within budget, I'd put a pretend sideoiler in it. Like a stroked 390(445) or 428 etc.

But that's just me.

[Jack Zupan]

The only engine that should go in a 427 Cobra is an FE in my opinion.

[Joe's Garage]

Even more a "true, honest reading" - chassis dyno, and those vary depending on the dyno used. It's gotten to the point where if I don't see a RWHP dyno chart, the numbers are meaningless.

[RodKnock]

At some point, I was thinking of getting my car chassis-dynoed but it involved drilling the sidepipes and installing some sort of oxygen sensor adapters IIRC. And while I was a bit uncomfortable with the whole installation process, I was told that I didn't have room or an appropriate spot(s) for it with my sidepipes.

[Detroit Bill]

To the OP have you driven in a cobra, any cobra to get a feel for power to weight?

Chad uses a tube that's inserted into the side pipes that has a sensor. Real easy. With his tune, my MPG was awesome. The best is to add sensors to each collectors. I plan on doing that with this build.

Here's just one short block I'm looking at.
I'll see what Brent and Barry, among others have.

I may also get on the list for a block or short block from BBM.

Craft Performance- (A lot of variable's I know,......, but I wonder what the basic HP/TQ range this is made for) ?

Kevin, if I may, I get the impression that with your sprint car background you are more comfortable than most with a "loose" rear... One that slips and slides a little under throttle.

I also get the impression that you are after the biggest baddest engine money can buy, which is why you've raised the topic of a stroked 385 series.

Make no mistake, the 385 is the nastier engine, and could probably produce more bang for buck than an equivalent FE if all was equally.

But from what I'm lead to believe, in your case it's not equal. Is that correct?
If I understand it right, your car is already to go with an FE (ie headers, engine mounts, bell housing, other ancillary parts).

If so salvage what you can out of your current FE, and have a 390 (445) or 428 built with some ported pieces and marginally larger than normal cam.

This will ensure you have the "correct" looking engine, with the cheapest buy in price, that will have more than enough power to scare the sh!t out of you if you mashed the pedal down for more than 2 full seconds.

At least that's what my logic is telling me to do in your shoes. It's WINS all round.
Either way fun and exciting times ahead for you.

Good luck man!

I could not have explained myself better ! Lol...

I started racing Briggs Go-Karts at age 7, moved up to 100cc Karts, mini winged sprints then was fired to drive a 360 dirt winged sprints at age 15. Drove for the owner for 4 years and winning a championship the third year. The we bought our own sprint.

I broke my neck and fused 3 bones. At race speed or on a smooth track, I was ok, but the joilting at slow speeds or a real rough track, it was very painful, so we hired a driver out of Knoxville Iowa. We retired when the stock market crashed, then the owner of the business where my wife has worked for 30 years, sold and the new owner changed the GREAT insurance to just Blue Cross and it sucks. With our bad health, very expensive medications, and the big hit,..... my hospital bills.

So, we don't have the money we used to.

Anyway, yes, I still love getting sideways, fish tailing etc. Going straight is boring !
I miss the days at short tracks like at our home track, 1/3 high bank oval, turn left at 100 MPH, or like at Knoxville's 1/2 mile, 140 MPH to 150.

Yes, I want a 428 or better, a Side Oiler, nasty sounding and gobbs of power, epecially down low.
Like the video I posted of the assumned, small block Cobra, is nasty !

But you got it bud, I'm not worried about gettin loose !

I ran a 514 in my superformance and it was a beast. More real world torque than my Roush Fe based 511 in my csx. I never raced them side by side but it would of been a very close race and I could of put about $25K in my pocket savings

That's what I'm talking about! It is far and in between but when the 385 series owners chime in I always see descriptions that include words like "beast, insane". The usual FE topics include words like "expensive and leaking". I think both can be great motors but I couldn't help myself. Heck I'm the asshol* who came out of the closet on how cool an LS7 would be so everyone had to see this coming.

Is it the crate 514 with 625 HP or the bit lower HP version ?

[fordracing65]

Get a block from Brent when they arrive. Get an intake from Brent. get some heads and a camshaft from Blykins. Get valve covers and spark plugs and pullies and wires and a carb etc from him also. Let him build you a motor and be done with it. He is a premier engine builder.

[FUNFER2]

Truly BUMMEND guys.

My 1/4 scale RC Sprint Car sold, but this afternoon the buyer backed out.

This is what she said.

"New message from: cosmo00015

Could I ask a favor. I won the bid for your sprint car but my friend that we all was chipping in to buy this car for passed away late Saturday night. We have No use for it now. I m sooooo sorry it is a Very Nice Car. He saw this car when you first put it on YouTube and was shocked to see it on eBay. We all was going to surprise him for his 54 birthday but now everyone freaking out. Let Me Know. Sorry

END-

The money was going for part of a block. But I understand her situation. I may ask her to only pay my Ebay listing bill.

Anyway, back to selling it.

[blykins]

I would not reuse factory rods....

Personally, I would get off the 427 thing. If the budget is not there to buy a 427 block, etc., and make it make big horsepower, I would go with a stroked 390.

[FUNFER2]

Speaking with my wife last night, and we now beleive it has to be a 427 or 428. Anyhing else may be disapointing. I wont give up on finding good deal on a old or new side oiler.

Good advise!

[blykins]

Then I'd go with a 428. If you had to, stroke it. You're less than 20 cubic inches off from a stroked 427.

[FUNFER2]

Do you happen to have a 428 that has been fluxed, sonic tested etc....?

[blykins]

Nope.....
