My camshaft is only .492 lift. And I can run anything I want. Bigger cams have been tried but they don't seem to work. If my motor had .580 lift or so it wouldn't get out of it's own way.
It will take some time but it will work itself out.
The Hemi stocker guys had fits when the street hemi E body got hit a few years ago.
Well back in the "good old days" that motor was 440 hp. NHRA decided that 425 (factory number) was to low So they made it 440 in stock and 480 in superstock. Before a car ever went down the track.
Is this what you want to return to?
Some very valid points to consider Art. Bigger is always not better in certain engine builds. This whole thread was based on how bogus the 5.7 Hemi was rated. Maybe we should all get back on track since this topic just turned into another, "bash the NHRA" thread. To those who don't like what NHRA is doing, past or present?...Go throw your keg's of tea into the Boston Harbor and have yourselves a party.

Anyways, There are at least 4, maybe 5 DP cars with this particular package. None of which have even hit the 1320 as of yet. Our 5.7 DP is still on the chassis jig and has already been bench raced and factored to death. lol Do I particular like the options on the 5.7 engine package that Mopar gave us? No... Could have made more power with less.

And Chris, we never even discussed TB size. Made the same power with a single blade 3.30" as a bench raced proclaimed, whoop azz factory supplied 1000 cfm. BTW, 3.34" and 3.54" single blade TB's net basically the same results. Now that we talked about how much air goes into the pump, we should talk about how much air goes out of the pump. Oh wait, we already discussed headers and wasn't that a surprise. ;)

Well, specially on the 5.7......540ft lbs at 4500-5000 depending on advance......I think Im gonna have the Stainless sent back and 3 stepped like Petes....

How's your current 5.7 build coming along? LSM will be doing our camshaft. Thanks for the heads up.

Good, a few more hours with a dial and some other things and itll go in tommorow (or saturday most likley) Ive got Jay going over the trailer and painting and putting in the new flooring, button up everything else Sunday and Monday and hit the road for Houston.

Looks like only Mandie can go unless I wanna wait till Drema is done Monday and drives down from a trade show up in Indy, but Id rather put 12 hrs on the road Monday and another 12 or so Tue and hit Dallas for some testing Wed. Well see......you know I just kinda wing it.....

Gonna be fun.

Shooting for 10.5 with the 5.7 with as little testing as we have under it but that will be in Stock legal trim. 10.3 by Vegas if all holds true. If I can keep it consistent with a weak *** advance and afr, but well add a little , ok a lot to it in Vegas if I can keep it together till then. I still think its way cool that no matter what I do it wont affect Stock HP ratings.....and the car can run in JA in Stock trim. I think, well see. Houston is just kinda more "testing" so well see, itll also be my First National, and while there are some people there Ive been told to "lean on" and have said to me they will make themselves available, the "drill" as it were will be a little different than Atlanta Div.

IF, IF I can get my Golf Cart okd....lol......I can always slap a "Mosquito Killer" set of decals on it.

Gonna be fun.

Always is.

It's the same motor as the 6.1 just less 25 cubic inches. It's rated at 305hp. Let's take a look at the specs boys and girls. It's 12.7 to 1 compression, it has a 584/552 lift cam, it has a single plane intake that is cast although it looks like a sheet metal manifold. It has a 1000cfm throttle body, a super stock oil pan and heads that flow well over 300 cfm right out of the box. Now let's compare this little jewel to the GM LS1 in the automatic version which is rated at 373hp unless you have a GTO or a Corvette and that's another story entirely.

The LS1 is 10.2 to 1 compression, it has a 515/515 lift cam, it's got a plastic manifold, a throttle body that is 2.954 round, a street oil pan, and good heads, although I bet they don't flow anywhere near the hemi heads on the Chrysler motor. Oh by the way the LS1 is 346 cubic inches.

The Chrysler should easily make 600hp. Any of you proponents of the new cars want to try and defend this deal.
I thought I would remind you all what the specs on this motor are. Just so everyone is paying attention.
