Default Re: Starting with C5R block....

z0sense - I saw that car at SEMA a couple years ago. Guys were just standing there in a stupor! That's when I started trying to find somebody to put a 502 in an SS. Hell, why spend a small fortune boring and stroking an engine when you can start with 50% more ci? I never found anybody that was remotely interested in the project.

Tell us more about your 427. Who's buiding it, what parts, who's going to make the intake, headers, etc?

It sounds like the C5R heads are the way to go as long as you can get an intake. I doubt Lamar has ever built a set. Do you know who we could get to build them if he can't?

What about air intake? That super sucker is looking pretty good to me.

Hogan's Manifolds in California will build you a custom intake to whatever spec's you want. they specialise in doing custom sheetmetal intakes. they have done an LS1 headed intake, but will do a C5R intake for you. Should run about $2,400 to $3,000, but ask them. their website is:

Hope this helps. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

am i way off base here?

800hp is not impressive at 572cid. cool, but not superhuman. fitting all that in an f-body...THATS impressive.

Perhaps you have not been to many car shows and seen what kind of hooch these cars can pull (that is for a fact). I really think that you are being a little immature and little negative about the whole situation.

GRB - I understand what you are trying to do.......get the C5R heads. You are obvioudly trying to be different then anyone else. Lots of people have turbos and lots of people have Stage 3 LS6 Heads.....no one I know has a set of C5R heads and a sheetmetal manifold, let alone on a daily driver (hence the reason for me buying a set). A 427 is a legacy in its own respect.....a C5R is another....and your GMMG ZL1 is another. Who else has the $$$$$ and the capability of doing such things. The car is going to rock. All in all I think you should stay all motor.

C5R heads are the way to go. All a motor's power is made in the top end. You can easily get these to flow, what a Stage 3 ls6 head will flow, with less work! They will clearly make more power and you will not be dissappointed at all. Hell if all else you could always take the heads and sell them in a snap if you weren't happy, but if you don't try them you may never know! We read reviews on LS6 heads all the time, but wno on here post first hand info about the C5R heads? That is why I am going to use them, and that is why I suggest them to you.

CHeck out this link to see the specs of this car. There were 69 of them built and they make over 800HP. They are a different setup (the reason why I didn't suggest it), but they are the baddest Camaro's ever available. No one has anything like this.

Ryan, go the super car registry and you can read all about ZL1s, COPOs etc. The link to the COPO page is good. There were originally 69 all alum. 427 Camaros built for a dealer named Fred Gibbs. He couldn't sell them. The car cost $3,500 and the motor another $4k. The car was never officially named the ZL1, that was the name of the motor.

I am only doing C5R heads. The reason I think that the Camaro was so impressive because it almost seems that it is reliable. Not necessarily as a street car, but it seems that i was built safe. The car has all the good stuff! Either way the car is unique in its own respect as will your's be.

For heads....I know of 2 or 3 people I would trust to build the intake for me and do the heads for me personally! What it really boils down to is time...I am sure that if you can trust Lamar....he would be the best person for you. It may take him a little more time to do them, but all heads use the smame principle. So in retrospect he may need a little more time to "research" the heads. As long as he has a flow bench, and has flowed heads before.....I am sure he can do your heads for you. So far as someone that has ported them before.....I think Lingenfelter is one and Katech is another, but I am not sure as to their pricing. I personally have a close friend to do mine. If you are seriously needing someone to build an intake or port your heads let me know. I can try and put you in touch with him!

maybe i was confused. but, yeah, i know about COPO's, Yenko's, etc.

(Back from vacation)

You could run the 38cc C5R heads, perhaps your builder could calculate what dished piston you could run to bring the compression down to say 11.5:1 up to 12:1.

I would not reccomend going over 12.0:1 compression.

Titanium valves are lightweight and will help mitigate valvefloat issues at high rpms but I think with this motor it's not necessary but it would be neat if you have the $$$ to commit to the project.

Neat project!

race only? much better. sorry, im used to vette people with more money than god putting in C5R-block 427's with ATI's and running 11's. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

it looks like you'll need QUITE an inverted some to run boost with C5R heads. perhaps even too much. you could go to a dish, but then have issues with quench. hell, you'll need ID pistons just to hit 12:1.

The 98 SS project is built to Super Stock specification. Mike Pustelny Racing (MPR) was responsible for the chassis. We are taking the horsepower from the blown C5R into a Pro Max Ultra Powerglide through a Dynotech Metal Matrix Driveshaft to a 4-linked narrowed Ford 9” rear end with Mark Williams ultra light gun drilled axles and third member. We are currently using Weld Magnum Pro II rims with Phoenix 32” tall by 14” wide slicks. The car will receive a set of license plates so we can putt it around town a little.

As far as the specs on the internals, I’ll get a build book when I pick up the car that will list all internal engine specifications. I know Katech designed the engine with a 4” stroke along with a 4.125 bore. Custom length rods and custom pistons were required to get the compression down to 9.1:1. This car will only be feed race fuel and should be a kick in the pants at the track, but until that day happens, well just have to wait and see. To be continued…

Tell you what Matt, if you're ever in Atlanta I'll let you drive the beast! You will one of but a few.

C5R is building a race car first and a street car second or so it sounds to me. I'm building the ultimate RELIABLE street car that pays homage to the 69 Camaro ZL-1. The all aluminum 427 was state of the art for that period and I want this car to be the same for this. I don't want experimental parts that are prone to break. Like I said, I want to be able to drive this car to the beach with as much confidence as I would have in stock SS.

The 18x11 rear Fikses will allow me to get a little more traction and should one of the Ferrari or souped-up BMW or Mercedes owners up at the club wise off about my Z06 I'll just say, "Screw your pretentious ***, I've got a Camaro at home that will blow your piece of **** away". That's why I decided to the Strange 12 bolt. Reliability.

That's what I want. A real ***-stomping American muscle car with a history. It won't be the fastest car on the street but it won't take crap from many either. A car that will look as good with the hood up as it does smoking the tires in third gear.

Default Re: Starting with C5R block....

then i will go back to my previous suggestion. Pick up a C5R block, Moldex crank, and if you'd like...(this may be overkill) a dry sump system from Katech. Sell your LS6 short block, send the heads to MTI..for the Stage 3 treatment. That will give you an easy 500rwhp NA. Plus, with the C5R covers that you'll need since you'll be doing Jesel rockers for your SOLID CAM <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> , it will LOOK like a nice small block. Do some research on cam grinds and email MTI for some specs. SW got 550+RWHP from a solid roller 422. That will give you the sound and feel you're looking for. And, rather than give it that cheap chrome look, you'll have a modern and clean satin look to it. Kind of a flashback and flashforward at the same time. Kinda like this:
<img src="http://www.frontiernet.net/~cendres/images/Z28/overall_engine.jpg" alt=" - " />

I'd leave the intake black though. In keeping you're A/C and ABS, you'll need to relocate the coils up under the cowl rather than where Chris had them. Headers and all that stuff is up to you.

If the C5R heads are worth 50+ hp with no reliability trade offs I have to have them. I don't want any regrets when this car is done.
