Well, a lot of Guys are asking about this so I thought I would show the specs of my Engine build. My last engine was kind of extreme and I did all the research networking and design by myself, so it was such a pleasure to do this one with RYAN J. He knows so much right off the top of his head it is amazing and we do think alike in many respects. I told him my objectives and he is helping me get there and he is NOT trying to manipulate or change that in any way. A huge asset in my opinion. RYAN is supplying the machine work and most of the parts and is setting up the heads and porting the intake etc. He is also going to do some mock-up to verify a few things and then ship me all the parts in a crate. One thing that planted the seeds for this engine was when I talked to Russ from Indy at MATS. I found out they had a 48 deg option for the 360-1 heads and that I could run a hydraulic roller. I will do all the final assymbly paint etc....
My objectives with this motor are :

Have fun building it.

Have something different and unique but simple.

Run 10.00 in Silvaliant in the summer heat.

Dead reliable valvetrain / low maintinance.

Reasonable driveability for the street.

Mopar R3 48 deg tall deck siamese block.
Bore 4.21, MAX CNC lightened by Ryan

Bryant max lightened 4.500 stroke crank. 340 mains chevy 2.00 pins.

R&R 4340 billet A-Beam connecting rods 6.300 X 2" X .866 small end. Super high end 3/8 bolts.

Indy 360-1 245RP CNC heads w/48deg option and finish ported VV job and assy by Ryan. 1.60 X 2.15 vvs. 360-3 Intake manfold ported by Ryan. T&D Rockers 1.70 ratio.

Custom CP Pistons Mirror dish 11:1 comp, X-Style strutted skirt design forging, lateral gas ports, max lighten pkg.

Custom Bullet Hydraulic Roller steel billet 48 deg cam.
Intake: 264 @ .050", 180 @ .200", .385" lobe, .654" lift with 1.70 Rocker
Exhaust: 268 @ .050", 179 @ .200", .365" lobe, .620" lift with 1.70 Rocker
109 LSA installed @ 105.

I have no idea on HP. But the car has run 11.08 with the 406 crate that is rated at 435 HP. So I am thinking I will make my goal. This car is 200 pounds lighter than my Demon was too, so I will not need as much power. Believe it or not that cam spec above is bigger than the solid roller I had in the demon.

Woah!

Awesome project!

I wonder how long till it gets a bit more cam *cough, cough* ?

Ron, wouldnt going to a bigger main diameter give you a little more overlap with the crank? NOt sure if thats a possibility, not sure if the r3's caps would allow much more to make it worthwhile. Betcha it's alot faster than 10.00 .. btw, how are those r3's from indy? Need alot of correcting or no?

I think the journal overlap was a variable that was thought about, so they simply let Sonny Bryant Crankshafts make the call. Sounds like they felt it was a non-issue for this application.
I thought they were going to go 1.88 Rod journal, but maybe that was pushing it abit too far.

Cool sounding project, Ron



You might want to consider a stop at the tractor pulls before you head out to the dragstrip with that

I think you'll go faster than 10.00...

So at 501 has anyone built one this big besides your 474.

Killer, A 500 + inch small block mopar street car that will run hard. You sir are my hero.

Please keep the updates coming as the build progresses.

Do you still have the Demon??

I love the valiants and yours is killer looking

That sounds like one KILLER setup man! i think you'll be in the 10's easy with that light valiant, maybe even faster! Have fun with it!

Good luck w/that Ron and like everything else you put together, it will haul a$$ and look great doing it!

Good luck with this project. Sounds like it will be a real stump puller! How good do those heads flow? Looking for 650 or more HP?

I wanna see the rods, and crank, Ill bet they are PIRTY!!!

Thats sound awesome keep us updated, love those small blocks
