Backdraft Engine Specs
Well, what did you select? Big block? True big block? Because I have to say all the big block cars I have owned have been way too heavy in the nose to justify the straight line performance, but that just might be me.
So an FE? Or a 351 bored out? Lordy that 351 Cleveland takes me back to when I was in college. Frankly, outside of the engine it was terrible. |
Small block LS3, was going to go with a Ford 5.0 but they never released the new transmission i needed. Injuries prevent me from using my right arm fully and i wanted paddle shift capability, so i went with what i know and what was available. It is modified and makes 95 more H.P. then a base LS3.

BDR car #260 started life with a crate 302 FMS 345 HP...not enough Voom-Voom 4 me. So, did a 347 stroker...now it is good enough for an oldguy! 11.90 @ 118 MPH got to love that 8.2 deck engines! BTW...electric blue
:D |
I liked my 500 hp small block, 347
but I think the best motor for a Cobra is the 530 hp 408w. $9,000 motor, drop it in and drive it with a 2 year warranty. A couple of my buddies had them and I drove them thousands of miles. Love them. They had the sound and we're very street-able. Good gas mileage for a Cobra. And VERY fast Dwight |
My BDR #153 has a 418W Stroker from Smeding Performance. Nice torque and accelleration

If I couldn't be a$$ed with a coyote or didn't want or "need" an FE then 450-530hp+/- at flywheel, a Ford stroked 408 is just about perfect choice for a bdr or spf or hurricane or Emerson or ffr or.... It's that sweet spot of power, efficiency, cost, reliability, look, sound, feel, smell and brand for a cobra... Enjoy. |

Before anyone gets their panties in a wad, it was just a joke! :3DSMILE: |
I had a small block stroker in the last car. Lots of power, and sounded great.
This time, I'm going with a 5.0 coyote with an Edelbrock blower. I also opted for the 6 speed auto. Something different. |
How many times have you ever heard "man, I wish I would have gotten a small block instead of this big block" compared to the opposite. I rest my case.... :)
(NOTE: I am 514 cubic inches of bias for the record.) |
Mine has an old FMS392. I swapped out the heads to AFRs.
I will put a new engine in some day. Dart block 427w 428w or something like that. Yes, always want more power. Not that I need more. |
1971 351 Cleveland, trickflow heads by T. Meyer, right at 550 hp. Not quite as much hp as my 33 willys at 1600hp, but a whole lot of fun on the streets with that Cleveland!

Ha Ha! Good point...never owned a big block with modern upgrades like Aluminum heads. Or even an intake for that matter. Guess that dates me a bit. I am open to a big block, but remember this is a street use car, and I am getting up there in years. My street racing days are long behind me. A modern 302 with liberal Aluminum makes for a very balanced, no power steering powerplant. But yes, 505stang, the 351 Cleveland in a Torinio when I was a kid was a great powerplant after some work...that would be a big fun combo.

I think a BB only appears front heavy because of the smaller tires in front, tending to understeer. A typical compact 3-cyl car nowadays has the same weight on the front axle as a Cobra, but only 30% on the rear. Not like 50/50 of a Cobra.
If all fails, and the cast iron puts you off, use aluminium engine (parts). I don't know how low you get get in weight for a BDR, but my RAM sat at 917 kg with room for improvement. |
