The compression ratio comes with the kit, you don't have to do anything but installe it, they have lower compression for FI applications. Dude you are very negitive person like if someone pissed in your corn flakes. Life isn't that bad, really. Remember, you can't start the hp count at a stock 300 because of driveline lose. So it's about a 100 hp increase as it was measured at the wheels. Every part that comes out doesn't have to excite everyone, if it did every body would all have the same parts. I'm interested in strokers as I'm debating staying na, not everyone is. The post was intended for folks who are interested in strokers, you apparently not being one of them. Thats ok, different strokes for different folks.
I am NEGATIVE to components that do not work! I am NEGATIVE towards people who push products that do not work. Stroked Ford 4.6L V8's DO NOT WORK N/A. You are wasting your time and money if you think otherwise. You want to do it, go ahead, but don't push it on others to follow your mistake. As long as I am here, I won't allow you to do that.
That Stroker article is MISLEADING. It leads you to believe the car gained 46 RWHP with the Stroker, but if you really look at it, it didn't. They tell you that the compression ratio is raised from 9.8:1 to 10.8:1 and they used CNC ported 3V heads on the stroker with the same bolt-ons as it had stock. That setup that made 352 RWHP is going to cost about $6300.00 minimum.
You can rebuild your 4.6L with the stock displacement with a bump in compression and ported 3V heads for about $4300.00 and make the same HP if not more than that Stroker. That is a fact and is my point. Reality if you were going to have the motor rebuilt by somebody or buy it assembled, you would be saving about $200.00 not going the Stroker route and have more HP N/A.
The bore of the Modular V8's is to small compared to it's stroke. Stroking the motor does not address that, in fact makes the situation worse. You have more air to fill through the same tiny bore space. Strokers worked on the older pushrod V8's because the bore space is significantly larger. The old 5.0L Ford V8 had a 4" Bore compared to a 3" Stroke, the 4.6L V8 has a 3.55" Bore and a 3.54" Stroke.
I have spent over 3 years researching Big-Bore, Stroker, Big-Bore Strokers. I paid attention to more than magazines, etc. In the end, I went with a 5.0L Big-Bore.
Strokers have been found that when keeping the stock compression ratio, using stock PI 2V heads, PI cams and a PI intake, that they
LOST 18 RWHP staying N/A compared to a stock 4.6L PI 2V. Adding ported heads, cams, intake, compression ratio to both the stock displaced and strokers, the difference is not made up. The Stroker never worked N/A and a 2V. You won't find that info printed in a magazine trying to sell you parts.
Ford has 3 Modular V8's, the 4.6L, the 5.0L and the 5.4L. The 5.0L version has not seen put into a production car but it is the best performing of the 3. The big difference, the 5.0L version has a 3.7" Bore while the other 2 have 3.55". The 5.0L has the same stroke as the 4.6.
The 5.0L Cammer comes from Ford rated at 450 HP at the flywheel, upgrading it to the exact components that the 5.4 Cobra R Mustang had bumps it to 465. The 5.4 Cobra R was rated at 385.
That is the direction I push people if they want to stay N/A, to go with the bigger Bore. A 4.6L bored to 5.0L using the stock compression ratio, Stock PI heads, PI cams and stock PI intake
GAINED 29 RWHP. The gain is even bigger when you add ported heads, cams, intake. Again info you won't find printed in a Magazine. There is only a handful of Modular builders that do the Big-Bore and none of them advertise in MM&FF.
A 5.0L 3V Big-Bore with those modifications would be damn near if not 400 RWHP. The extra cost would be $1200.00, but you would have an application that works N/A.
