I didnt intend to start a flame here or straight out attack you, but that looks like what you have done to me here.
First off, sorry I didn't notice that you already had the Z spec tranny.
Heres your first quote of ignorance...
"A 347 adds more than 40 to 50 horse skyman. I seriously think you have no idea what you are talking about. A 347 will give you 375HP. Proven Fact. With my setup I am pushing over 440HP."
Adds more than 40 or 50 horse to what? Im talking on a well breathing 302 given around 300hp w/ heads, cam, intake etc. You add a 347 its going to add roughly 50hp just given the cubes. Your saying a 347 will give you 375hp proven fact? With what heads is that? E7TE's? I highly doubt it. With what cam? What compression? What intake? So I can just go get me a 347 slam it all together and make 375hp. Oh jeeze I wish building engines was that simple. And don't go quoteing how much horse power you have untill you dyno your car. I'm willing to bet you your first pull wont even net you 390hp.
Now I'm looking at your parts list. Doesn't seem like your engine is going to be running very well here with out a crank. Doesn't that usually cost some money? That puts you over $3000 right there. Also were those 30lb Injectors free? I doubt it. You say you got your heads and intakes for only $350. Thats damn cheap, but I can't argue with you on that really. Oh by the way, my off road H-pipe was only $89 and I didn't get any special discount. No fuel pressure regulator? Going to be tough tuneing that beast with out one of those.
Also looks like your running that stolen Cobra computer. Anyone thats been around stangs know the cobra computers are sh*t. I would think someone that has rebuilt 25 5.0's would atleast not to know to use a Cobra computer. You ought to go get yourself a A9L (Just a peice of friendly advice).
Your using a B-303 cam in that car. You dont mention 1.6 or 1.7 rockers. If your running 1.6's theres no way that cam is going to be enough to get 400+ hp out of that 347. Even with 1.7's it may not be enough. The high duration maybe the only thing that gets you there if you use 1.7's.
Also what kind of compression are you running? 13.5:1? Then you may make 400+hp. You never specified this.
This link you show of a 370hp 347 engine uses World prodcuts heads with 2.02" valves. MUCH larger valves then your GT40 heads have. Though with porting they should flow about the same. So where does the extra 70hp come from? Are you going to rev your engine to the moon? It sure isn't going to make power that high with that B-303 cam. Also this engine is just magically rated at 370hp. They give you no dyno #'s or actual real life facts. Yes, it will probably make that much power once setup right with all the right components and tuned well, but this is no way in hell to gauge what kind of power your engine is making.
I'm not normally an ******* . But when someone comes out and attacks me when they don't even know theyre own crap or have anything to back up what they are saying then I do get a little irritated.
Honestly though, no flame intended.
