Let's assume...bench racing a claimer motor.

[milner351]

I'm not sure i understand the whole claimer dealio - but I am always surprised at what the good Clevo guys can do with a relatively mild 351 or stroker (408ish) with stock aussie heads (2v ports, closed chambers but still BIG valves and ports compared to SBC)

Unfortunately you likely can't build a 5.0 liter coyote for $4000.

I like the idea of the "budget" EMC class however - it brings the big brain power to the same monetary constraints us regular guys have to deal with. This will undoubtedly be a 55 gal drum of win for the hobby at large.

Mater, thanks for the thought process there. That's what I was looking for.

Milner, what does a set of stock Aussie heads cost?

[SpiderGearsMan]

403 olds is a no go due to windowed mains , not sure if the 307 has em , can't remember

Here's a set for $380 bare:

here's an example of a stroker build:

Now we're getting to some viable alternatives. Thanks a bunch.

the aftermarket has girdels for them to keep them together. they also have 4 bolt main caps

I would do a Chevy v-6 using a lot of very good used small block chevy parts saving a lot of money with 2 less of everything and they have a lot of very worked out used parts left over from Arca and Busch days just laying around.

I would go with a 289 ford, with N351 heads. Heads sell for like $800 would leave room for good port work and valve train. Could use 302 mustang style intake for EFI.

4.8 with ported and milled 243's.
LQ9 with LS3 heads...

The LS3 heads are the basically the same thing as the L92's, though they might have a smaller chamber....... Thing is this is a competition of averages, so where the L92's would work great for peak power numbers, they might not work so great in the low lift areas once you start increasing lifts and durations........This was one the factors I was looking at when I was picking the cam for my LS1......all the cams would lose power down low to get the increased power higher in the rpm range, I finally found a cam that basically mirrored the stock power numbers below 3600rpm and then exceeded them by 4600rpm......I think this is the kind of setup you'd be looking for........

Another thought is if your limited to 6500rpm, would it be better to have peak HP come in at lets say 5500rpm as long as you could keep the power after that close to the same as peak HP......Meaning if peak HP was 620hp at 5500rpm and you were still making 600hp at 6500rpm that that would be a 1000rpm stretch where your making over 600hp....., I would think that would increase the averages, wouldn't it??..........

[Stich496]

after looking over some new gear..
I'd change to the ls, III 6.2 catty with the new tunnle ram intake (as close as sheetmetal as you can for 1/20th the money)
and a ms based or factory ecu.. and you'd have 1500.00 at least left to playwith.. claimer engines = blue buttons

nice idea but will never work..
to many builders can take a 6-8k hit, and let someone claim the winning set up. if they are getting free press, word of mouth ad.

nice idea.. better idea.. would be the 4000.00 engine challenge.. pay your entry fee (4k) and pick your engine from the corner over there.. ford/mopar/g.m.. you have to use the parts that it came with.. eccept pistons.. and engine management..and cam,
go.. the one that gets the most out of that wins.. big guns wouldn't be able to keep try'n new parts and mods. over and over again. on those hard parts.. cause lets face it the big guns can keep try'n stuff now and then sell what they didn't use on a claimer engine on other customer engines..
this put more in the brain trust that outlay of parts and testing stuff and then another.. want more stroke start offset grinding, want a longer/shorter rod, figure it out..

Subscribing.

Whoops, I though we were actually racing this thing against other cars.

Read carefully Bruab, it's all secret code.

EMC has a 4k claimer series being held at your local Racetrack. You can buy beer, fill the car, get a hotdog (nathan's dog's by the way. yummy) and hook up to the air / water @ .75 cents a gallon to keep it cool!


I think I would be looking for old Cleveland junk. The destroked 400 idea seems to work pretty good. Aussie 2v closed chamber heads.

Repro alum heads - http://www.ausfordparts.com/ ~1500.00 cuz I'm tired of getting cast iron in my eyes.


/edit - and a time machine, but you clowns don't get to claim that. I'm going back in time to put bugs all over Kaase's shop and see what they did with their truck motor.

Can I tune this thing on my own personal imaginary dyno? Buddy Rawls had some opinions on huge intake / exhaust (super speedway sized CSA) and a comparitively really small cam that I would love to test.





/edit three - and no stupid rules like you can't make your own phenolic spacers so you can use the Ebay Boss 302 Tunnel Ram!

/edit four - bulletproof glass in the dyno cell in case some jackass shows up with a "cool can" full of hydrazine. I don't think you can see the green flame in the dyno exhaust?

[Beagle]

that is the most twisted backwards read I have ever let sink in.
and you forgot suffixed zero for the megasquirt moron.


I agree with stich. make some money if 4000 is the limit by using cheap tried and true, and ignore youth with their megasquirters squirting all over everybody..

Scott, see the big grin? I think that means you are being teased. According to my decoder ring, your leg is being pulled.

Barry, tried and true any more means some form of inexpensive electronic sensors. When you consider how easy it is to monitor *everything* and make changes *right f*ing now* , it's pretty hard to argue with EFI. I can go out in the garage and get an EFI engine running cheaper than I can a carb'd engine. BUT - There's another thread we can dig back up if y'all want to hash out the EFI / Carb stuff (again... sigh.)

On the other hand, I've never been able to get home with a busted electric fuel pump by putting some fuel line in a gravity fed 5 gallon gas can attached to the hood with bungee cords. Cough.

Lol. Carry on... :D
