I'm just wondering how much power and how lond did your stock block last?

I'm getting tuned at Apton in Cinci this coming tuesday and I want to add as much nitrous as it takes to reach the 500 to 550rwhp mark.

BTW, in a nutshell I have a forged 347 with ported AFR 185's and a nos dry kit that I will take above the 150 shot as long as the fuel system holds out. The block has also been de-burred and steel threaded pipe plugs have been installed inplace of freeze plugs, and I also have a Canton steel stud girdle.

I also only need the engine to last until the begining of November, so if you think taking it to the 600 mark will last until then I'm game also.


Thanks

How the hell did you get the intake to fit under the stock hood? I seen a stock block crack right around 500. Took a big shot of nos and cracked down the lifter valley all the way threw the block. So when it was taken apart the block actualy broke in two parts.

The intake didn't fit under the hood nor did I use aftermarket fuel rails. I had to use a 1 inch spacer to clear the fuel pressure regulator. I also had to cut a nice hole in my nice stock hood for it to clear. I will get a pic and post it sometime this weekend.

I recently saw these bolt on valley supprts that are supposed to support the valley and keep it from splitting.According to some know it all in another forum,a forged bottom end is a waste.I recently built mine and dont think ill have a problem with 8-10 psi,but everybody says it will never last, i guess it depends on the tune.

Neither the top end or bottom end girdles will do much of anything to help keep the block together --- about all they do is help keep the pieces from littering everywhere when it does come apart.

As for what HP level - pretty tough to predict. You have guys out there at or slightly over 500 rwhp that have motors that have held together for some time; and you have others let go the first few times they asked it to generate that level. You'll only know what yours did AFTER it's done it -- it's simply not predictable because there are too many variables. However, once you enter that 450-500 rwhp range you're definitely in the area where many stock blocks are at their limit. If you're serious about big NOS shots on the stroker the only way to go is with a stouter block - Dart, etc.

Is Apton in Cinci a good place to get your Mustang tuned? What all do they do to your car during tuning? I live in Maysville, KY (about 60mi from Cinci) and need a place to take my '89 GT once I start working on the motor. Thanks.

If your going to break the block, at least do it like that


I know sureshot ran like 600hp through his stock block and it was fine. Other ppl have broken them with far less (like rick said). Basically, its a crap shoot.

I was actually pondering this on my drive home from work tonite. Theoretically, wouldn't it have less to do with the hps you put out and more to do with the way you drive? If you're burying the tach constantly, that'd put more stress on your block than shifting at less rpms on a higher hps engine. Of course, I doubt many people granny drive their big hps beasts, but for arguments sake, does that sound realistic?
