Hmmmm..... I swore Ryan specialized in small blocks .

Definately keep us up with the tech side of things Ron. Always interesting to see one of your builds.

I think your going to have to add a few bars to the valiant Ron. Your vehicles make me all warm and fuzzy inside. .....Phill

i would never have thought it possible to go that big in a small block. You said it had a tall deck...how much taller is it than a stock block? anyhow, thats an amazing motor you have!! I would be tempted to put 273 valve covers and air cleaner on it and drive it down to the cruise with 3 inch flowmasters or something..hehe

I'm thinking speedworld might have an issue with you... AGAIN!

Sounds like a killer.

I don't think it will need any more cam to run the #'s Ron wants. It's not a race motor... I did'nt really want to do the 1.7's, was going to do 1.65's but it's tough to get decent lift with hyd roller lobes. Also the more RR will help pull pushrods back closer to pivot point to help out with pushrod clearance, although in this case it really does'nt matter with 48 option on heads & Ron wants the pushrod area of heads fully opened up for weight reasons.

Talking with Joe @ Bryant, with the low RPM of the hyd roller cam & the low(er) power level around 650 he felt journal overlap would'nt be an issue. Crank will be neat, it's getting every option Bryant offers for lightening, largest rifle drill they offer on the 340 main, Star flange, Aero Wing counterweights etc.

Pistons will be 1.01" CH, & even with the .866 pin it still has to have oil rail spacers, because the dish is pushing the rings down. Compression is little up in the air, will be somewhere between 11.0-11.2:1 Depending on what CP gets out of the dish, Ed thinks a -22 will be biggest possible just doing some rough math on it. He said for sure they can get -20, so will be somewhere between -20 & -22 & then I can manipulate chamber volume some to try to get it where we need. Should be LIGHT... Doing Forged Side reliefs & max lightening package. Doing a Trend H13 tool steel pin....

Total seal is making me a custom 4.21" .043/.043/3MM ring pack

We wanted to do Titanium rods, but alot of companies who used to offer them have stopped doing them due to material costs etc. Crower could do them but time frame was no good..... Was going to do a 300M Lentz, but they did'nt want to do a single set in the 2.0" Journal in a reasonable timeframe. If we did 2 sets, would have been quicker... So Ended up going with R&R out of Illinois, all their rods are custom billets, they don't really do off shelf stuff. Mike, the owner was real easy to deal with, & is doing a 6.30" X 2.0" X .866 with 3/8 ARP Custom Age 365 bolt, in an A beam design, he said it should end up in the 540-560 gram range, which is what we were looking for. Also he is going to make the big end as compact as possible as Ron wants to use an internal oil pickup tube, which should be entertaining.

The Heads will be the 48 degree -1 INDY's with the Raised Port 245 CNC intake, & Small CNC exhaust port. I'll re-work the intake ports for little more cross section, should flow in the 360 range with the 2.15 valve. Ron wants heads & INDY intake max lightened, so will spend "few" hours on Bridgeport wacking misc bosses off.

I started working on intake yesterday & getting enough plenum volume in it while retaining a 4150 flange is an issue.

It's definitely an interesting project.... & I've gotten used to telling companies I'm talking to about parts for it "I know it's extremely unusual, but that's what I want" LOL

NICE

That sure is a cool sounding combo you guys are building!

What's the height of a Tall deck R3?

Ryan said a 6.300 rod and a 1.01 CH with 1/2 of a 4.5 stroke comes up to 9.56"...~ Standard 'blueprint' mopar height.
i was thinking the tall deck was 9.8 or so...no?

I'm just asking....Are you going BIG for the sake of going BIG, I think with a 1.4 rod ratio and nearly 4900 fps of piston speed at 6500 I don't know if the VE would be as good as the same rod with maybe a 4.25 stroke spun a teeny bit higher.

David Vizard made a 440 cube SBC several years ago fir Super Stock Magazine....it didn't really live up to its "on Paper" potential...I happen to know both David and the guy who bought the motor. Don't get me wrong, it runs great now but maybe not in terms of HP per cube. Of course a Mopar should be better on general principal!!

I think the specs are dead on but I'd try to get at least 270cc of intake port on it....what will be the final port cross section, I figure you'd want about 3.25 sq inches?

Cool project...It'll be a milestone small block (V10 Viper size V8) for sure!!

That's just wild, 500+ci smallblock, makes my 425 seem small Good stuff

Ryan,

Thanks for the info! I was thinking a W8 might be the "optimum" head for that combo but the Indy should work just fine. The deck height confused me I didn't know if they made a tall deck stroker block or not....maybe they should with 4.5 cranks out there! Sounds like a killer motor and the cam specs (also a Bullet HR) are what I run in my 517 with the Chapman max wedge head....to me it's been the perfect cam for a 500" motor (regardless of block size!!), nasty thump and wall to wall torque and pulls even faster way upstairs (mine has pulled 6800....real quick-like)

I'm sold on Bullet's grinds.

Can't wait till you fire that bad boy up and that A body post is what I was what I had in mind when I first conceived of this motor...I'm jealous!!

So you're sticking around the tens for the rollbar deal?
Thats a wild motor. The biggest I've seen was a 462 from alberta.

Yes, I only plan on running 10:00

W-Series Heads were out. I wanted a normal intake manifold with normal water routing, thermostat housing etc. Just bolt it on and go. I had to fabriacte many of the fittings AND the thermostat housing on my W-9 motor and I decided not to endure that again. Most of that stuff was not readily available when I built that motor.

Just a thought, would using head spacers help? that way you could possibly use slightly taller pistons/rods as far as the top ring stays in the actual bore? When does cam clearance become a problem?

Head spacers is a good idea. But Head spacers will add complexity and possible reliability issues, so I won't use them. Since we are milling the manifold for a custom fit anyways we could have done that I guess. But I think we will be fine with what we have. I want a simple, reliable, low maintinance Engine with some balls so I can run the number at the track. No power adder and nothing too exotic. Sure some of the parts we are using are considered exotic like the pistons and crank and rods, but thats because I want light weight stuff and I want the best quality I can get. The crank had to be a billet just from the fact that there are no forgings that could be used. I have no problem with a forging and I would use that 4.25 callies crank in one of my motors. But with this one I wanted to go BIG! When you open the hood you will see a normal small block in there with big block displacement and TQ. I am not as concerned about rod ratio and Ryan is. Someone just posted about building a 4.25 X 6" rod motor and that is about the same.

Cam clearance in a Mopar Small Block is not an issue.

Ron.....
What rear gear for this car?

I put a 4.10 gears in it, because it was the most universal I could think of. The car has 28" tall tires now and does not look that bad, but will need taller tires with the new Motor. More traction and gear ratio. I set the car up to accept a 30" tall tire.

That's just sick! I had no idea you could build that many cubes into a Mopar SB....Can't wait to see/hear it run.
