Vehicle weight VS MPH. I have never dynoed an Engine and I probably never will. Of course you might want to look at 60 ft to see if chassis efficiency is there etc. But that will not affect MPH much so you can pretty much use MPH. What I am saying is, in a properly set up car the MPH VS Weight will tell you. I would only use a SINGLE dyno, to compare two engines, or to compare different mods on a single engine.

Had I known this years ago, the engine in my Cuda would probably be different. Visions of P5 Hemi heads and 500 cubes come to mind.... My only question after seeing this post is why has nobody ever built one before now? Why is this all of a sudden common knowledge, yet I have never heard or seen anything even close to that in a sbm before now.

My only question after seeing this post is why has nobody ever built one before now? Why is this all of a sudden common knowledge, yet I have never heard or seen anything even close to that in a sbm before now. My answer is: just how much is this 500" sbm going to cost???? That might be why nobody has done it yet? Compare that to a 500" BBM and you can quickly see why. I have to say though, it should be one very neat and original build that's for sure. I'm excited to see what happens...too bad you won't stick it on our dyno Ron, that would be neat to get Dulcich down for a day of pics and a nice Mag spread. I'm going for a completely different approach with my new engine...it's a 360" W2 headed R1 block deal with 48� lifter bores. I too hope to go 10.00's but I'll be using race gas. Just thought it would be neat to do 10 oh's in a street-like car and no stroker so I know what it's like to go against the grain Plus I just don't have that much $$$ to spend on an engine build LOL!! Keep us updated, we're going to want lots of pics Brian Hafliger

Why is this all of a sudden common knowledge, yet I have never heard or seen anything even close to that in a sbm before now. Ron's old motor was 474 inches..... INDY sells a 471" Kit now off shelf.... All it takes is a big crankshaft. Most guys doing SB Mopars are not willing to spend the $ to be honest. However, a 4.5" crank in a SB package will not really be a great "race motor" combo (it's too much stroke IMO) That's really why no one has done one.... It's unusual to spend this kind of $ on a motor that will not be a max effort deal. The 4.25" crank would be as big as I'd go for a race motor that needs to turn RPM & make big power. The journal overlap on this 4.5" will be scary with 2.0" rods.

As many of you may know I was in a waiting for an aluminum Block. One that would accept all the production components. Basically a Aluminum R3. But, I have not even heard a peep out of anybody for ages. And I predict it is possible it will NEVER happen the way things are going. So I give up hope. Yes, I probably would have gone with the callies 4.25 stroke forged Crank with all the lightweight machining and then maybe a solid roller to make up the power difference. But the rods would have been the same (except a .927 pin) and pretty much everything else. No CNC Block lightening would have been necessary (or wanted). I am very weight conscious and have gone to great lengths to lighten the front of my car. So with this Motor I probably spent about $4000-5000 just to lighten the block (full CNC lighten program), crank, rods, pistons/Pins and he is even doing a bunch of milling on the heads AND Manifold for weight reduction. I think Ryan said the Crank might end up less than #40 pounds. I don't think the average person realizes how much weight reduction in the crank alone can be achieved. A 4.500" stroke crank for this engine without any weight reduction could weigh #70 pounds. That is 30 pounds and it is right in the front of the car and it will help with power slightly as well. There is a lot of "bad" weight in a crankshaft just riding around doing nothing. But I think the Callies 4.25" Crank stantard weight version costs around 1800 and my Crank is going to end up around 3500(balanced). An aluminum Block probably would have saved me money in the long run. Or who knows I may have still gone for the Bryant Crank. But it would not have been as likely. Once we decided to do a billet the sky is the limit on stroke so we maxed it out. The cost is pretty much the same not matter what the stroke. SRT DEMON ONE SEAT

Ron Silva OP top fuel Joined: Apr 2005 Posts: 1,880 USA	The Valiant weighs 2900 pounds without me in it and with the 406 iron headed crate motor. This new 501 engine should take at least 50 more pounds out of the car and from the front. The radiator I have is from Ron Davis and is basically a standard radiator out of his catalog. But I ordered it with a STRAIGHT botom outlet. I am using a 20" engine driven HP flex fan from Permacool. They pull a lot of air. The shroud is off a ford Fairmont or Granada. 5456712-MVC-004S.JPG (445 downloads) SRT DEMON ONE SEAT

No. Nothing in my cooling system will change except I will be running a Edelbrock water pump. I know there is better stuff out now, but I have never been able to make an electric fan cool in the summer heat. I like to go to Del Taco in the summer and go through the drive through.

I know of a guy who went from roughly 400 inch smallblock to 450 inch smallblock, and because of the heads(230 indy)he has seem very little gain in performance, the car is just harder to hook because of the 4.25 inch crank instead of the 3.79 and 4 inch stuff he used to run. The 500 inch smallblock is a cool deal, and as a "one off" piece its mighty intriging. From a practical standpoint there are bunches of ways to get a smallblock to go 10 flat easily on pump gas with way less inches and cost, but Ron has the "cool factor" pretty much sewn up 69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight 418 BPE factory replacement headed stroker, 565 lift solid cam Best so far, 10.40 @127 1/4 1.41 best 60 foot 6.60 at 103.90 1/8
