Have I maximized output?

If it's a production block, then all the other stuff doesn't matter. A factory block just won't take that kind of horsepower for long....even with the fancy main stud girdles, valley girdles, etc, etc.

Greatly appreciate the posts & the time spent. fantastic info, some over my head a little. I think "AL427SBF" actually got it right...."don't need the extra power". Sounds like a can of worms that gets pricey for a checkbook mechanic, or could ruin a great motor. Answers to Q&A:

> Ford Racing Crate Motor with Aluminum "Z" heads motor model M-6007- C347. The guys @ the dealership who ordered the motor for the original owner said it could hold over 700HP with no trouble, but that's all I know.

> Paxton NOVI "SL". I understand that this design takes care of the back pressure generated, but that was just my interpretation of the literature. The dyno guys said that the back pressure can also be vented back into manifold just in case- I may not have provided the precise wording here.

The guys @ Unique also said the rear end could handle well over 700HP flywheel) with no problem, but you never really know who you are talking to.

All in all there are enough what if's that I think I will leave it alone. Runs great with no issues.

Again, my first time on the technical blog- good results. I did find the car in the "for sale"" section last August.

Thanks again for the help & any additional thoughts....One more thing... thoughts on a soft top? I hear they are junk, but in CO there area lot so pretty good driving days in the winter. I understand the rigid canvas tops are workable?

Thanks,

LH

Salesmen....very good at lying.

I can show you some pictures of some 302 blocks that have split in half at around the 550hp (flywheel, not rear wheel) mark. With the girdle still holding the main caps together.

I would not be on a blog if I had thin skin- no problem. Sounds like a good place to leave the motor. Don't want cooked pistons, split block or busted rear end. Excellent advice from all. Very please with the Cobra (albeit a replica). I was a Vette guy many years & got tired of hearing about the Cobras. Even the mild ones beat about anything else around. Re: "Zoom This": my first choice was a stroked 351 like the 418, I just did not find one in the price range I needed.

Thanks to all for the help. Any thoughts on the soft top?

Thanks

I didn't mean to come across crass, and I apologize if I did.....but just trying to stress very strongly that the production blocks weren't made for that kind of power.

It seriously yanks my chain when plainly dishonest people take advantage of people wanting to spend hard earned money.

I'm sure the Unique FIA car is awesome with that kind of power 520HP! Welcome to the brotherhood... have you been to a Homecoming yet?

Blykins, I was not referring to you re: the "smart A-- remark". That was AlS427 & those were his words. However my point is the he was actually correct, I did not need more power, at least if I wanted to stay in a safe range with my components. Some times one-liners say it all. Again no hard feelings just good advice coming in. All of the posts were very good & helpful. Very sharp bunch & I am pretty much a newbie.

To PDUB, thanks for the compliment, I think it is a pretty good car & I will just keep it that way. I will check out "Homecoming- not sure what that is. I have joined the Mile High Cobra Club & they are a great bunch & very active. Again thanks & any thoughts on a rag top would be great.
