Default 2010 Stock Longblock Race Thread

OK so in another thread a few guys have been tossing the idea around of doing a little project and some grudge racing. Rules would be simple.

1. Completely stock longblock with the addition of valvesprings (No modifications of any kind. Pistons, rods, rings, bearings, cam etc must remain stock and not rebuilt)
2. Anything else goes

Fuel, turbo, tire size, transmission, etc will be unlimited and should offer up some good fun.

What do you guys think? So far we have
1. black98ws6ta
2. Josh@KY-Turbo

I will keep adding names to the list and have also added a poll to see how fast you think they can push a completely stock longblock.

You forgot to state that it has to be in an F-body... there are people here with fox's that could get there a lot easier than the fbod

Are you allowed to port and polish the heads as long as factory valves remain?

Casting Numbers. Easy to tell if you know what your looking for. There is a huge honor system involved in this. We are not talking about having a dedicated chase for low ET. Just some some fun and Parts breakage.

I think you should be able to modify the STOCK Parts, as long as their all original parts, no swapping different model parts. milling, decking, porting, etc, should all be fair game as long as you all run the factory stuff. same with porting oil pumps, etc.

I understand where you are going with this. The point we are after is the Stock Long Block record.

You get into milling, Porting, Decking and such then you may as well just build the engine and be done with it.

I am going to buy a LS1 Long Block pull out. Run it as it is. Its a challenge for me.

Very cool. I think a lot of people will be surprised to what stock LS motors can be pushed to.

if thats what youre going for...unmodified, bolt ons only...then springs shouldnt be allowed either. The whole point of not touching the engine is to see what you can do with it without changing anything internally, correct?

Allowing springs is to keep from floating the valves. We can mince rules all day long. Build what you want to. Put it in a Fox body Mustang.

We are going after the Stock Long Block LS1 F-Body record. Valve springs will be the only modification to the Long Block. Thats where the mods stop on my Long Block. Past that it is bolt on Components. I plan to find a 01/02 Long Block in good working condition. I dont plan on removing the heads. I am keeping this simple.

I might be down for this ... I have been 9.51@147 with a dismal 60 foot and weighing in at 3250.

My heads are stock 317s but have been cleaned up a bit and valve springs added as well.

The whole idea is a completely untouched stock longblock with the exception of valvesprings. No porting, no touching, no nothing. This will also only be in a F-Body car meaning 1998 to 2002 Camaro or Firebird. The idea is to push the limits of a stock motor, valvesprings are basically something you're going to have to change and very cheap and will make the stock motor MUCH more reliable under boost. Valve float could be catastrophic.

I can understand the stock heads thing but limiting it to F bods is not going to make for a very exciting contest you will have like 2 maybe 3 guys fighting it out..... My car weighs 3250 and will be heavier next year so I do not see how this puts it at any advantage as there are many 3200 lb f bods running around?

Why the exception for springs? If you're going for stock, go for stock.

Sorry... I didn't mean to burst your bubble

Everybody knows that you can build a Fox and be faster because of the weight... I THINK the point of this is to get a Full interior car, without ANY modifications to weight savings and see how far you can push the mighty LS1 down the 1320 the fastest
