How Much HP Did My Stock Block Foxbody Make?

[@blownfiveoh1212]

I'm making 600 rwhp on a stock block 306 with a T-trim Vortech (Renegade pulley 19lbs of boost) and Trick Flow heads, even while using a GT40 intake and shorty headers, but I did split a few blocks along the way.

Back in the day, some folks were running Pro 5.0 with a stock block at 770hp. We all knew it was going to explode one day, it was just a matter of when. FTR, 1989 is the baddest year no matter what. Most aggressive stock cam and precision media cast intake before ford went to sand cast. Everybody with an 1989 dominated right out of the box. The fabled 87-88 speed density cars didn't pull as hard. Close, but not good enough. We had many on fresh gatorbacks running high 13s. Drive it like you stole it...

Good to hear stories like this. For every story of a block split at 500 or so there are 10 more stories of guys making it last for a good while all while enduring abuse. It's more about keeping rpm below 6500 and using the best fuel possible and you also want to have an efficient setup and good tuning.

Was this a completely stock bottom end, or upgraded with better pistons, rods and crank?

[@BrotherTom]

@@dennisrobinson8008 Completely stock bottom end. Car was originally an automatic with 60k miles until I bought it.

[@dennisrobinson8008]

@@BrotherTom Thanks for the feedback. Is the e85 known to stretch the limits of the bottom end slightly in the fox world? On other manufacturers where you might have a block/gasket/rod or piston limitation on 93 octane, the e85 stretches it out a little bit more due to being extremely resistant to detonation and running cooler. So on the manufacturer i'm thinking about it lets those guys run another few psi very safely, where if they ran 93 octane, they'd bend a rod, destroy a piston or blow the head gasket.

[@BrotherTom]

@@dennisrobinson8008 that is a very good question. I think you could run meth injection with 93 pump gas to get a similar affect. It all comes down to the tune and RPM you push it to. If you stay under 6500rpm you 'should' be safe. Once you start pushing that you are playing with fire.

[@petrolhead8851]

@495whp with the stock block that block isn’t going to take any abuse! That’s really pushing it if you ask me! We kept my brothers 95 gt with the exact same set up as you @430whp to have that 70whp cushion which is where these blocks tend to break. I think 450whp would’ve been more safe because you’d be able to beat on it all day, with 495whp you’re going to have to be careful with the amount of pulls you do

[@BrotherTom]

A lot of the "500hp issues" come from over revving these motors. The stock internals were not meant to go 7k rpm. If you keep your shifts under 6500 rpm (my MSD rev limit is set to 6200) and have a good tune your motor should be fine. Now that being said, the tuner I use usually gets you 'that number' and then pulls a degree or two of timing so that you don't get silly on a hot summer day and blow up your motor. Thank you for watching!

[@petrolhead8851]

@@BrotherTom you have a big point on the revving part! I completely forgot about how these blocks don’t like to be revved high either lol

[@midnight347]

You are talking about it as if it's an exact science at xxx hp the block breaks it doesn't work that way. He has a really efficient combo and a stand alone it's good good solid tuning with good fuel it'll be fine. You don't tune the car to a certain hp level as if that is going to keep it alive. You should worry more about real high rpm and having the best fuel possible more so than worrying about a certain hp number on the dyno.

[@petrolhead8851]

@@midnight347 I don’t think you realize that these blocks will split in half regardless of how good the tune is or good of a fuel you’re using, it doesn’t even matter if you’re using a stand-alone unless you’re using all the safety features and even then that might not save you from splitting the block.. these blocks have a horsepower limit, I’ve seen them throw rods through the block and break in half many times, even if you keep the rpm’s low sometimes that won’t save you, everyone has their own experience

[@midnight347]

Richard's videos are with no accessories spinning and no driveline loss and in many cases he just has straight headers. 600-650 on his dyno the way he tests isn't much above 500 rwhp in a car. It's the difference in the way he tests which is why bone stock 225 hp 302s.make 260 hp on his dyno. It's always been around 450-500 rwhp. You can go beyond that but you really gotta have good fuel and good tune and watch your rpms. If you're trying to spin it to 7k it prob won't last. Everyone always brings up Richard's videos like that is proving something different when you do the math his limits are about the same as the 500 REAR WHEEL limits everyone has always talked about.
