Project Stealthram / AFR195 355 project finally almost finished... http://members.aol.com/jmatlock88/car15.jpg http://members.aol.com/jmatlock88/car24.jpg I did a lot of work this weekend. We'll have rw dyno numbers by the 21st of Oct for all who are curious. I wanted to start this thread and update it regularly with new info as the project is finished. Thanks! |
Wow that's a great looking engine! What made you choose the AFR 195 over the 190? Also, are those projected HP/torque numbers in your sig, or did you do a dyno? Great job! |

"The exceptional flow characteristics, ideal operating range of 2000 rpm to 6500 rpm" vs "The exceptional flow characteristics, ideal operating range of idle to 5500 rpm" I'm stalling at 3500 rpm so any low end numbers are a waste basicly. Also, are those projected HP/torque numbers in your sig, or did you do a dyno? [/B] Great job! |
Cool beans. What cam are you running? Do you program your own proms? I figure this is a SD setup, so i'm curious. Ive wanted to toss a pair of AFR's on a ZZ4 shortblock with a S/R for a while now, and I am curious what kind of numbers could be expected with that setup. I'm still quite a bit away from being able to afford it though. Can't wait for the dyno on this, Thanks for sharing! |
500 horsepower... with air conditioning? Hot damn you're a lucky man. How come I can never come across those types... :rockon: Rock on. |
OHHH SWEET! Look what came in the mail today! Too bad it was on order since september. :( http://members.aol.com/jmatlock88/exh1.jpg http://members.aol.com/jmatlock88/exh2.jpg |

I dont program my own proms as of right now, but I will definetly be looking into it soon. I would really like to dig into ed wrights chip eventually, compare it to my original prom, and learn from there. My buddy has a zz4 shortbock with some fastburns instead of afrs. He's projecting 430HP with his combo. You'll definetly see more power if you use some afrs. A gm crate motor (zz4) is definetly a great way to go. I still dont know how everything's going to turn out with my motor once it runs, and I'm sporting zero warranty. :doh: I cant wait for the dyno on this either... stay tuned! |

Here is the motor a few stages back... If all these pictures arent loading, just hit refresh a few times on your browser. AOL hosting really sucks. http://members.aol.com/jmatlock88/eng7.jpg |
Here are the final Rear wheel HP numbers. Account for approx 75-80hp loss in driveline. I have Ed Wright on video saying "Congratulations, This is the most powerful non-blown tuned port (aka mini ram, stealth ram, super ram, tpi) motor I have ever run on my dyno. Great job, Jerod" So pat my self on the back...it's fun to brag a little. Thanks for listening to the story... |

Nice! Good to see some good numbers put down on a Stealth Ram setup finally... :D Those after a chip tune? |
Originally posted by madmax Nice! Good to see some good numbers put down on a Stealth Ram setup finally... :D Those after a chip tune? Yeah buddy, my stock chip and my superchip both needed tuning badly. The motor would run rich at idle and lean at part throttle up. Throwing the 30s in there made everything more reasonable, but it was then mega rich at idle. I took the fuel pressure way down and advanced the base timing clear to 22 degrees to get her to run without glowing the headers. Running like this, it was decent to drive but terrible performance. We guess about 260 RWHP on the drive up based on the subsequent initial dyno pulls. The first pull with Ed Wright's first stealth ram "best guess" chip ran 308HP. We were really depressed, but everytime Ed came out of his secret room he had 20 more HP to plug in. It was a miraculous scene. All 10? dyno pulls increased by 10-30HP when he changed the chip. I have about 40 degrees total timing in my chip and Ed said that the top end liked a lean mixture. That may help some of you doing custom tuning w/o the luxury of Ed Wright at your back door. |
GLAD TO HEAR!!!! pretty damn good numbers if ya ask me!!!! :hail: :hail: :hail: :hail: :hail: :hail: :hail: :hail: i wish i had someone near by...... |
Maybe I missed it, but what kind of cam do you have in it? Hydro roller? Chris |

Originally posted by JMatlock88 Yes, apologies --they are just computer generated numbers. Not from desktop dyno software, but a $3K package that is supposedly much more accurate. How accurate, we'll find out Oct 21st. If anyone wants to come watch, I'll be in tulsa at Fastchip! Thanks again! [/B] |
Originally posted by JMatlock88 Yep, it's an old 1969 4bolt 350 with a retro roller cam in it. Specs on it are 224/224 110 560/560. Ed Wright thought that I needed 4-6 degrees on the exhaust side to make the most power possible. I seem to think he's right on that once you undnerstand the sheer multitude of combinations he has seen in the past. I will probably be switching to a 224/230 cam in the next year or so. Even if it just helps the n/a power a little, it will definetly help when I decide to hit the gas. Any opinions? Chris |
VERY nice numbers! It's good to see a healthy HSR combo on the dyno finally. Get that thing to the track and show us some 11 second slips. |
Impressive. Is that with the Street or Competition 195's? |
I am runnin' the street 68cc 195s w/ about 10.7:1 |
OMG thats awesome!!!! Congratualtions! |
Originally posted by 12sMustang That's a damned big lift cam. How does it idle? Your cam's specs are actually pretty close to mine, though I have 48 less cubes. I think you have an impressive SBC. 380 at the ground is a bunch from any N/A combo. Good job! Chris |
Oh, one other tid bit... The tach is off about 500rpm around 6500! whew! My tach reads 6500 when i'm really spinning 7000. That pull we really were twisting her. I just now got my msd pro billet distrib in the mail. Too bad it was too late for the dyno run. Any predictions on peak HP gains using this distrib vs stock? It would be interesting to note... |
Nice engine, awesome power What i really wanna know about are two things: 1. How hard is it to retrofit a roller cam? 2. What tranny is backing that beast up, i blew my stock trans out, I've gotta feeling i'm gonna blow my new trans out. After i bolt up my nitrous kit, i KNOW i'm gonna drop it....and while i'm at it, what about the rear end? |
Sweet a$$ numbers!!! Too bad i cant see the pics for some reaon..... im still running the stock chip in my motor, and its just like you said, FP down, Timing up, good to drive, not terrible by any means, but I know theres alot more power lurking in the chip! |
Hot damn you have me excited. I'm about 50% of the way through my engine swap, and we're very similar in specs. The only difference is my engine is a 396 with 10:1 compression and my cam is a 236/242 112 lsa with .555 int .576 exh. Other than that, I'm running a Stealthram (like you) and AFR 195's (like you). Hopefully the extra cubes will bump me to an even 400 rwhp, but we'll see. If my power isn't up where I want it N/A, my whole rotating assembly is forged with billet splayed caps to hold up to the NX kit waiting at home ;) Congrats on a killer set up, I can't wait to see where mine ends up :) Edit: Just noticed you're running the street ported 195's. That makes me all the more excited because I'm running the 100% competition CNC porting and I have an extra 41 cubic inches... hopefully that will give me 400 rwhp :D. Congrats again! |

Originally posted by Marshall89ws6 yea i have an idea for you that wouldnt be too hard at all........ just slap a set of 1.7 ratio rockers on the exhaust side to give urself a little more exhaust lift. but ur talking about degrees which would require the cam..... well its a thought Yep, that wont really work. Not to mention clearance and binding issues... .560 is already a lot of lift. Thanks for the input nontheless! |

It has kevlar bands, carbon fiber clutches, other nice internals, and a b&m cooler and megashifter. The driveshaft is an stock fbody aluminum shaft. The rear is a 10 bolt with 28 spline moser axles, cclip elim, slp posi, 3.73 GM gears, and a summit stud girdle. |

How did you set your camshaft endplay? |
Had Morton Machine degree it all in. I didnt have the tools... |
Also, most graphs I see have torque curves that are flat at some point. This is not the case with this engine. Comments? I know the charts for tq and HP are different and the tq ones favors a negative slope but still. |
fyi I'm using a cam button |

Will someone volunteer their server space for some video files of the dyno pulls? I think it would be fun to share. If you would, I would greatly appreciate it. The files will be pretty big, so you'll have to have a lot of space and bandwidth. Thanks! |
Nice #'s....can't wait to see some track times. Very good results from the HSR. What valve covers are you running? I really don't like the ones I have and I wouldn't mind replacing them. TIA! |
A huge congradulations. that's a sheetload of power! So your running the 224/224. On the graph it shows it peaking about 6000-6500, is that the actual engine rpm, or is that with your tach being off. Also, did you install that cam straight up, or with advance or retard? I'm asking because that is one of my cam candidates. thanx |
Wow...i love you man...if you were a chick, i'd ask you to marry me. The engine is sweet as hell and the rest of it sounds incredibly built too. I'm lookin into the trans rebuild. It's none of my biz, but might i ask how much a machine of this magnitude takes to build? |
:hail: your car, did you have to modify your hood at all or did it clear okay? |

Awesome machine you've got there. Please report back any increase you get from that distributor... that would be of interest to all of us :) |
I dont plan on putting the car on the dyno again after putting on the distributor so I guess we'll never really know. My butt dyno isnt very accurate. I will probably put her back on the dyno next summer when it gets a t56 just to satisify my curiousity of how much RWHP it will free up. |
Good numbers. What exhaust did you run on the dyno? |
Dual 3" non-mandrel bent exhaust from local shop with 2 3" 40 series flows. They dump in front of the rear wheels through stainless steel lt1 style tips. edit: I changed my mind about running the mufflex 4" setup...$$$ |
