What happens to a 5.0 block if you stress it to much.....................!!

[panozracing]

UWE...that quote is HIGH....you need to call Mike at Total Engine Concepts (TEC) 561.842.2813 (tell him Brian Goldburg with the Panoz sent you).

I have a 351 dart, afr 225 we bought castings and my engine builder put the valve train in, jezel shaft mount solid roller rockers, JE pictons, victor jr, drysump 3 stage pump, peterson 4 gallon tank, canton drysump pan, depending on what stroker you build (ours is a 427 ci) you wont need a big carb....our 390 cfm nascar restrictor carb gives us 500 FWHP @ 6100rpm and a 650 cfm mighty deamon is 600FWHP @ 6500rpm......etc....I will look for the receipt and post it.....

All in was 17k with EVERYTHING you listed.... now we had blown stock 351W panoz GTS engines so we used a few items. But using your pricing and adding those in the motor is still right at 20k (not installed but dynoed and tuned plus 3 track visits in florida for free to tune at the track). This is DRYSUMPED.....the pump was over 1k alone.... I would say our engine is higher than you highest. Also keep in mind it will do a hell of a lot more than 600 hp....I could only image putting a 1100cfm carb, super victor intake, some BIG headers and turn it up to 8000rpm....I would bet 750FWHP....

at our current 500fwhp we are getting 100+ track racing hours before we even think about opening the engine up. It is one AWESOME motor....we have built many and none hold a candle to this one....

I will look for the build sheet and dyno's....

you wont pay tax if it ships out of state and that will cover shipping.

I've got 83k on my LS6 and it still makes north of 430 rwhp cam only. It's had countless HPDEs... granted no 6 hour enduros, but I think the beauty of the LSX is that it comes with much of the stuff needed right out of GM.

If you're building from scratch then the costs equalize.

That's why I went that route!! :-D

WOW, $20k for a motor build, I cna only imagine what kind of power i could get out of the LSx for $20k!

For under 15k you can get a new ZR-1 LS9 motor! and it comes with a factory warranty :-o

[panozracing]

I baught a ford stroker motor with a warranty too....once!

that 5.0 block didnt SPLIT IN HALF doing HPDE. The stroked LSx motors that run ST1 get around 40 race hrs. between refreshes and I promise you that motor brand new isnt close to 20k http://www.pfadtracing.com/blog/?p=71 (I will say I havent truely priced this kind of LSx....just a guess).

So what does 3 refreshes of an LSx motor cost and add that in too.....

You got that right Brian. The block was used in a professional race class where there are 40 spec cars going hard at it. There is a lot of panel damage and they can break any mechanical component invented by man.

A good example; they had a problem with gearbox reliability using T10 based boxes with a straight cut gear set fitted. As a solution they allowed the fitment of Jerico boxes. Now these cars only make 430'ish hp so are probably 410 - 420ftlbs or torque at the flywheel. Well, now they are smashing Jerico's and only after a small number of races!! I have the utmost respect for the strength and engineering in a Jerico as I have run one, but seems nothing is bullet proof in racing...........

Eric the new ZR1 LS9 is more like $38,000 from GM. The LS7 427 is $13kish. Stroked LSXs wear out faster due to the piston/rod angle putting side force on the bore.

I'd wager that a stock stroke all bore build would run for a long long time. Katech makes a track attack setup using a 427 block but with the stroke of of the 4.8 truck motor (or maybe the 5.3)... it displaces 5.7 liters but revs to 9k

Oh... and if you were to contact any LSX tuner in the country and ask for a road race spec motor from scratch it'd be $15k on the cheap end up to about $35k-$40k for all the fanciest stuff. Katech is the premier shop for this type of work as they build all of the C5R and C6R motors.

Ok, so I was off by a few thousand! lol

Still 22k for a crate Ls9 isn't bad!


I'm not knocking the ford motors.....much..... LOL

Eric, you would have to be a very brave man to spend that much on a crate engine and then do any serious racing on it without stripping it and actually setting it up properly for racing. I expect you would end up with a bunch of very expensive paper weights of you put that engine in a decent race chassis and then raced it seriously for a season.

There is a lot of time and effort (hence $$) put into making sure that race engines do not hand grenade. I have found this out the hard way on a couple of occasions!! Particularly when treading the line between wet and dry sump configurations and max rpm configurations for stock parts.

I think there is a bit of a line in the sand where you can be competitive and get by but thereafter if you dont spend the money upfront you end up spending a lot more later. This applies equally to all manufacturers and I am an ex GM racer (all my favourite paper weights are broken GM bits!!).

I think Smokey Yunick (top man that he was) had this about right when he used the phrase....."as far as race engines go, if you are serious, you better make sure you have a pair and a spare".

We just yanked the 351 out of my cobra today because I am selling it at a roller. I'm not sure where I should put it...

You could make a really nice margarita blender with that thing...

I hate chunks of ice in my margarita. More horsepower is always better.
