Im stuck between trying to find a 94-95 5.0 or maybe a 96-98 GT. I had a 95, and i kinda want something different, but im scared i'd regret the 96-98 from how people talk about them.
I beleive the Teksid block in the 93-98 Mark 8's and 96-98 Cobras is the strongest 4.6L block. It will handle up to 1000HP.
That would be the block to base a 4.6L stroker motor on.
The regular iron GT block can handle up to 500HP. The internals can't though and must be upgraded
Only if you bolt them onto a Non-PI car. Compression was the same with Non-PI and PI head cars. The compression bumped a little in '01 for 9.0:1 to 9.3:1.
If you bolt PI heads onto a NPI, the compression will go over 10.0:1.
Engine for engine, the 5.0 is very easily modded and will cost less to do so. The big thing with the 4.6's, they respond to power adders very well. The big downfall, is the crappy internals. The major positive, once you get good internals, the iron block can withstand lots of HP, way past what a stock 5.0 block can handle.
They have weaker rods/pistons just like the 5.0L does.
If you want all forged/arp hardware like the 03/04 Cobra's, you'll get the price tag as well.
And what I meant earlier when i said Mustang owners had to shell out an additional $10k in the 90's to be competitive with the GM cars was that if you wanted a from the factory Mustang that could at least come somewhat close to keeping up with the Camaros/Firechickens you had to spend an additional $10k and get a Cobra, and you would still be sucking tail pipe. And just to be clear when I say additional I mean that a Cobra cost about $10k more than what a Mustang GT or Camaro Z28 did. Yes the Mustang outsold the F-bodies, luckily for Ford performance does not necessarily equal high sales. I for one was embarassed that Ford stood back and did nothing to make the Mustang gain ground in the performance non-war of the 90's. I hope history does not repeat itself!
You know David, actually you can bolt on 4V heads on an iron GT block as well.
__________________Stock motor + 33 PSI = 999.7 RWHP
I just got back from the dyno. The car made 999.7 RWHP thru the nonlock converter on 33 PSI. Those are uncorrected numbers, the corrected numbers were 994 HP. We had a little issue with the MAF dropping in voltage and leaning us out otherwise we could have kept turning it up. Once we hit about 28 PSI the turbo stated picking up 55-60 HP per 2 pounds. I think its possible to make another 50 HP at 35 PSI. I forgot the dyno sheet but will get it tomorrow. I also weighted the car and it's 3380 with 1/2 tank of gas. Should be close to those 8's now.
Yes, the 'gt' blocks are capable of 700-800hp pretty easily. They are thick. I got an 02 SOHC block in my back yard right now...I wish I had some money to do something with it
Teksid blocks are referred to as the strongest, I recall reading one racer was pushing near 1700 hp in it...
I just think it is funny how everyone downs the 2v, when it is better than the 5.0L
I did the PI Headswap, and on my first tank I got 24.9 mpg, mixed driving. I was confused...lol. And no I wasn't that easy on it...
It's probably because the aftermarket is better for the 5.0. Look at factory stock. 5.0s are still out there competing with the "better" 2Vs... In fact, I think everyone with 2Vs has given up. 99+ start off with more power ~30-40 rwhp, but also more weight. You can make a more power from an n/a 5.0 build-up cheaper than you can from a 4.6 2v non-PI build-up for the money for sure, and I think a even a PI headed car when you start shooting for 300+ rwhp. Stroker 5.0s will make 400+rwhp without much fanfare. I couldn't even begin to address making that kind of power with a 2V, though I admit I know much more about 5.0 combos. The limiting factor on a 5.0 to me is the block strength, which you can push the limits of before adding forced induction. It should would be nice to have the 700-800 hp potential without buying a ~$2k block (after machining). The other nice thing about 4.6s is the abililty to rev them. After researching what it takes to make a pushrods motor build rpms, I've begun to appreciate the relative ease with which you can make the OHC motors do the same thing.
People down the 2V (especially the 96-98) because they are just anemic. And to really make them faster, you are pretty much limited to forced induction. Man, a friend of mine recently asked me what the performance potential was for the 4.6s, and I told him that I know that a 4v swap is difficult and pricey, but a lot of people go forced induction. So, he wanted to know about how much he could find a supercharger for one. So I started looking.... Where the hell are these things.. Seems like every company out there has 2 kits for a fox, one for 99+, and one for 05+, but they don't list any as 96+ or 96-98. What gives? Is a 99+ kit going to work on a 98-?

99+ start off with more power ~30-40 rwhp, but also more weight.
2V blocks can bolt on 4V heads, is this a 100% bolt on affair? Also the Teksid blocks are the 96-98 Cobra block? I am going 4.6 in my car (yes going from 5.0 to 4.6) and want to build a motor before I drop it in. I'm thinking all motor, some healthy cams, (4V obviousely) gear it to run hard NA, then slap a turbo on it later down the road...
