Broke7 Steggy 03 Cobra vs 351W Vortech SQ 93 Notch Options

[Speeds8erM-1]

My friend Jonathan made the video. I was riding in the notch, the first run was a second gear roll and he spun off the hit pretty bad, the second run he started in third and had a little traction issue going into fourth, got sideways a little but Broke was already pulling.

Only 498rwhp with a blown 351? I know a few blown 302s that would hand him his ass.

Yea but just because somebody does something doesnt mean they are trying to make all the power in the world. You show me a stock block 302 making 498 rwhp, I will show you some cars that are about to have split blocks. It's a mild combo.

Dam, i thought the notch would take that one.

I had over 498 whp in my stock shortblock Notch for several years and never split a block. However it was pretty slow it only traped 128 untunned and on a small cam. I never ran it at the end but it was probably only a 135ish trap car.

Depends on how it's driven, 500 rwhp stock block 5.0 is a time bomb period. Seen plenty of my friend's split them taking it easy, even girdled, balanced good internal setups. www.turbomustangs.com would also agree

Hmm... Not sure I would say its all in the tune. I drove the shit out of mine, ask aquaman!! I street raced it pretty much every weekend and at the end I launched it on slicks. I didn't powershift when I had a T5 behind it but with the Proshifted TKO I did. Not sure I guess on what you mean by how you drive it....

[Speeds8erM-1]

Seen plenty of them with mid 11 air fuel ratios, methanol, girdles, everything and still die. Very few get as lucky as you did. You also have to figure if somebody makes 500 SAE and then a cold night comes along and they are actually making 550 or so, the block doesnt care about sae numbers it just cares about what it's actually making right then. Maybe you had a mexican block and didnt know it? lol

Now that surprised me.

Perhaps, I had a problem with compression on one shortblock but that stuff happens. None of them were mexican blocks so thats not the case. I feel that some are just stronger my shortblock at the end came out of my friends car running 10's (stock shortblock reringed and rebearinged). Maybe I was lucky, but another friends vortech fox made 500rwhp with a stock shortblock aswell. Maybe we were just a lucky group of guys or it was in the tune There is a lot more in a tune then just a good AFR.

The mexican block thing was a joke. I have seen a few race cars run on the stock short block for awhile but they didnt get alot of street use. Ever check out the stock block chronicals on www.turbomustangs.com or even the Corral? My friend's block split making less than 450 but he never got it tuned and the balancer had slipped or something, so he had ALOT of timing in it. I have seen cars last a little while at 500 or less than 3 months making close to 600. Blown Saleen on the Corral was running a MILD tune with methanol on a stock block making 511 and it bit the dust hard when he didnt even expect it.

There is more than the tune to it on those junk blocks, more like luck, how many miles, how high you rev it, how often you beat on it. C16 wont even save those blocks if you make enough power.

How many miles? around 5-6k a year one motor a year

How High did you rev it? 6200 which helps a ton!

How often do you beat on it? Everytime I drove it

I ran a mix of race gas and 93 pump gas. But, my friends 500rwhp fox didn't just 93 (his other answers were the same except he probably drove it more).

6200 is a little lower for a blower car, probably what helped, stock cam or no? Not many stock short blocks stay in the game. The turbo cars do seem to make it longer though. Friend of mine broke the crank in his stock shortblock GT with nitrous. it was running 97 MPH traps in the 1/8, so I would say under 500 rwhp on that one too.

Barry D over on turbomustangs.com basically kept splitting blocks and putting stock short blocks in before finally going to a mexican block. Car made 620 rwhp. He had a hyperutectic short block come out split but the pistons were FINE, shows the tune was on for those crap pistons to handle it, wouldnt take much detonation to kill them along with or before the block.

Yeah 6200 is a little low but RPMS + HP is what breaks the block so if you control the RPMs you should be ok. My car had a trickflow stage 1 cam for a while (when it trapped 128), but I switched to a F303 cam at the end. Turbo cars last longer because they do not have to make as much Crank horsepower to make it to the wheels since they don't have to use some of the power produced to turn the supercharger. As for the nitrous cars they usually break the block first since the "hit" the motor so hard with the surge of the nitrous.

The Notch hasn't checked back on this thread in some time and just stumbled on to his responses. Looks like Sedanman did the honors though.



An old buddy of mine 93 LX 450hp untuned.... eventually fried a piston at E-town vs a GN.... Block still intact though.

Another buddy of mine, also the guy who would work on my Notch when I had it... 91GT Vortech Supercharger low 11's on street tires, mid 10's on slicks and that was his show car, full weight. Stock block, still intact till this day and he beats the shit out of his cars come race time.

My 92notch that I sold... 540rwhp on stock block and he beats the shit out of it... (The Bastard!)

I don't know but I guess your friends just have some shitty luck. Could they be boring their blocks paper thin? could they already have pre-existing cracks in the block to begin with? Too big a hit of Juice? Overrevving? Highmileage blocks? or what I believe it to be is... Some Chevy guys loosening up some bolts in your buddies Mustangs before race day?

Hey, I won't argue the fact that the Ford factory 302 is the weakest of all weakest links but they're not as bad as you think they should be. Though Sedanman has the absolute best arguement for this thread since he's actually had the sick combo between the both of us. I'm still a small fry in that catigory... 220rwhp before I sold it. I was one wedding day away from becoming a big dawg!
