This is what I don't get.... 930 HP / 580 ft-lbs with tunnel ram intake with dual holley 4 bbl carburetors 890 HP / 570 ft-lbs with single plane intake manifold and holley 4 bbl carburetor Torque is what moves the car. I'll stay out of it now.

The R3 W8 380" motor in my Valiant made just over 900 on 2 different dyno's. At 3080# I ran best of 8.67 at the Dutch Classic this past weekend. The new parts and machine work cost about $35k if you assemble yourself. Sorry, I simply don't believe it makes that much. AndyF.........the only reason I mentioned an inline head was the price range some were throwing around, an inline was the only thing to be in the neighborhood on cost. If you are not used to building high HP motors and you know the motor that you have that makes 700hp costs X amount of dollars......it is hard for most to fathom that 200 more hp will likely triple the budget at least. I mean......it's ONLY 200hp more.........right, how tough can that be.......LOL!!! I didn't bring Comp motors, Aussie Pro-Stock and that type stuff into the conversation, because that stuff is in another world

Here is something else for guys to think about..........So lets say we believe the power claims for this splayed valve motor pictured. And lets say we know what a killer set of splayed valve heads vs an inline head flows as far as air. So if we hear of an inline motor with heads that flow way less air than the splayed ones, is making over 900HP......are we buying that claim?...........I'm not While total air flow is NOT the be all end all number, CSA, air speed and many OTHER things also come into play, it is a pretty safe assumption to expect to make 900hp, that you will need a head that moves right at 400cfm of air. THAT thins the herd of potentials very quick

That HP number is based off the ET and weight in the Wallace calculator. Wonder if basing it off the speed would yield the same numbers.
ET is how you get the car down the track. The speed is what relates to power
I know Chris, I know Tony and several others. Several times the things they are quoted as saying they CAN do or HAVE done, leaves out several key pieces of information on the full scope of the project............and I will just leave it at that

If you read the internet and listen to guys at the track...........there is a swinging dick on EVERY street corner with an inline valve, wedge smallblock, that makes over 900HP. I have been doing this stuff for a LONG time and have NEVER seen one, be it a Ford, Mopar or Chevy. As I said, you can do it with some canted valve stuff, but it's still not REAL easy and will be at a min of 40K if you do it with all new stuff.
I have done several 434ish Chevys and Fords, with the BEST 15-18* heads you can buy. A good one will make between 840 and 880, depending on cam, compression, rotating weight, etc. I have yet to see a Mopar head that was BETTER than the best off brand, so I am going to say it can't even realistically be done with an inline head........regardless to what some dyno sheets may say to the contrary we'll I always in joy or input always controversial and backed by a lot's of personal experience how ever only making 840to880 shows your lack of engine building experience Prostock truck ran an inline valve W8. And there are many many many comp eliminator Motors that have all achieve 900 + horsepower with an inline head. Always check history before you say something can't be done, yes it can be done and yes it is expensive. Patterson, Chris and QMP to name a few have all done it

I implicitly said that Pro-Stock Truck and Comp motors were NOT in the discussion, because they are in a whole nother world. Was talking run of the mill, single carb, real world motors, with 15-18* wedge heads, like most people build.......NOT 10,000 rpm motors, built for clutch cars or motors for 1400lb roadsters in Comp eliminator Seems impossible on this site, for anyone to take anything within the context of the ENTIRE discussion. They want to take ONE thing you said in ONE post, run with that comment and ignore everything else. You guys carry on...........I'm out

153mph@3080#'s is 884hp per Wallace. Edit:your post wasn't in Monty before I posted, but I'd say he's definitely in the wheelhouse

Based on ET and weight, Wallace says 934hp.........based on MPH and weight, Wallace says 880hp............So now, do we know any more than we did before...........NOPE Moroso dream wheel says...based on ET/weight-910hp, based on MPH/weight-850hp. Valiants aren't very aero, giving up some MPH over a different body. Stack some gear, get it to 60 and 330 on a good track can get it to ET well. Air was decent at Maple Grove early in the weekend. Just some observations. Beyond that, I'm just here spectating.
If the results don't match the theory, change the theory.
