Its Christmas in April!!!!
Look what I found on my doorstep this morning!!!
http://i219.photobucket.com/albums/c...e/DSCN1764.jpg http://i219.photobucket.com/albums/c...e/DSCN1765.jpg http://i219.photobucket.com/albums/c...e/DSCN1766.jpg http://i219.photobucket.com/albums/c...e/DSCN1769.jpg Will pull the heads, cam, and rocker assembly..Adding a set of AFR 195's (58cc), RPM Air Gap, Edelbrock cam, CompCams rockers and lifters, and hardened Manley pushrods, Holley SA 770.. Should be in the high 400's for hp and tq. Its always something!!!! BTW, I will be selling the Fast Burn aluminum heads, Hot cam, rockers, and I have a Vortec-style Air Gap intake.. Also my ZZ4 (basically TURNKEY) will go up for sale when I swap out the motors, in a few months. The ZZ4 has 400 miles on it... Any interest in any of the parts, PM me. I'll figure out a price soon. Damn this is fun! :cheers: Rob |
Merry Christmas !:party:

Hi MS,
You can sit in your new seat and look at this new motor. You're going to be BUSY!!!! Regards, Alan |
God bless us...everyone. :cool:

Awesome!!!
A couple questions for ya.. 1) If you were planning on replacing the top end, why not get the zz383 short block? 2) Why the change to the AFRs? There can't be THAT much difference in performance between the Afr and Fastburn to warrant spending $1600?? One comment... With what you are spending on this thing, do yourself the justice of a good cam. I would get something custom spec'd for it....Or at a minimum get a cam from Comp with their good lobe designs or something from Lunati's Voodoo line. Personally I would hit up Straub Technologies or UDHarold for a custom hyd roller. Way more power across the range. Please stay away from Edelbrock cams as they are junk. The right HYD roller in that thing and the bump in compression and it will make 500/500.... You are gonna have a blast with it....congrats on the new motor. |

You are gonna have a blast with it....congrats on the new motor. 1) I got the long block for $3500, still in the crate and under warranty (though not transferable) from a guy in KC craigslist. Its a $5200 motor from GM. 2) I had purchased the AFRs to originally install on my ZZ4. The same heads are used on the Super AFR ZZ4 (http://www.sallee-chevrolet.com/Chev...8s/safrzz4.cfm) offered a couple of yrs back. I was able to get them for $1400 including having them cut to 58cc to keep 10.1 CR. I had already purchased the Air Gap for the same ZZ4 project. I also have an Air Gap for the Vortec heads on the 383... 3) I called Comp cams with all my specs, and the tech said he could do no better than the Edel 2204 (recommended by GM), without a loss of vacuum... I havent purchased a cam yet, but am going with the Comp tech's advise...as I am not a cam scientist... Here's the ZZ383-500 offered from GM.... 514hp/491tq thats with a single plane intake....probably less with my dual plane Air Gap... http://www.crateenginesonly.com/Chev...8s/383-500.cfm I'm always open to suggestions as I want to do this 383 once....I have NO PROBLEM keeping the Fastburn heads, and that would be an easier build without having to change out the heads. I would then just sell the AFR's. I already have an Air Gap intake for the Fastburns...so can go either way...I would love to just swap out the cam and get close to 500/500!!! Dont know if thats possible... So far I have the ZZ383 long block, a Vortec Air Gap, a regular Air Gap, and a set of AFR 195's...so can go either way. Thanks! Rob |
All of that makes perfect sense now!! That was a hell of a
deal on the motor. Since you already have the AFRs, I would definetly use them. The 58cc chambers may be too small to keep the compression at a safe level so check into that. It would probably be around 11-1 comp. Ofcourse the right cam can bleed some of that off. Hang tight, I will get you a link to Chris Straub....the kick ass cam guy. He will run all the data for you and tell you want you need. He has forgotten more then the Comp guys will ever know.....give me a few mins.... |
aj,
Check out this link...the "Premium ZZ383-425" http://www.crateenginesonly.com/Chev...ZZ383-425P.cfm As far as I can see, this is MY motor with a RPM Air Gap intake...I really see no other differences between this and the baseline ZZ383-425... Would the Air Gap account for 25hp and 35ft-lbs??? The cam...12370846 - Hydraulic Roller Cam - 222/230 duration - 509/528" lift GM claims 450/488. I do not care about the absolute accuracy of the numbers, but simply the RELATIVE difference between the baseline ZZ383 and the one mentioned in the link.... If I use the AFR's, then I'll need rockers, new pushrods, new cam, etc... what to gain 50 hp and basically the same tq??? The AFR's used on the Super AFR ZZ4 and the ZZ383-500 are milled to 58cc...provides 10:1... ALSO....all the ZZ383 specs I read online show 9.7:1. My motor paperwork states 9.9:1.... Am I missing something here? Sounds like, for the money, I should bolt on my Air Gap vortec intake and go...might make the most sense?? Comments? Rob |
It will be worth your time to contact this fella. He will spec out exactly what you need...you can buy directly from him also. Have all of the engine specs handy when you call him....This is a good investment.

I am not sure how much it will cost you in incidentals to run the AFRs but....if there was even 30hp gain with them, it would be worth the expense of new rockers, push rods etc. I mean the fast Burns are good heads I'm sure but no doubt the 195 Eliminators will outflow them by a healthy margin....especially if they are cnc. Remember, pay me now or pay me later.....if you don't put the heads on now and get it cammed right now, you will always wonder what it "would have made".....not to mention you will always want more power. Also remember once you put it in the car and the exhaust is on it, fan/ps/water pump etc are all belted on, you lose a lot of power, upwards of 40hp so.....if you can make it up now with better heads and a real cam, you should. Also remember a good cam may not be a "big" cam.... It's all about the combo. That's where these cam guys come in.

A real Edl. RPM Air gap intake is a good one. You can make 500hp with it easy....I would stick with it. Especially since you are not running a crazy converter or low gears and have overdrive.... All of that you need to tell Chris. I would look at getting a better converter also if you change cams. I don't remember your tranny/converter combo but.....any decent sized cam is gonna want at least a 2800 or so converter. Get what you pay for on those also...

Thanks for the advice so far... Rob |
+1 on Straub's Cams
be money well spent , and you can be sure no HP was left on the table.. What are the specs on the Springs that come on the GM Heads ?? That might also limit you on you cam choice if you decide to stay with those heads ! |
