Which Hyd. Roller Cam?? And new Brodix IK200 Pics
First of all, Thanks for all the help on my previous Posts
Heres an Update on the GMPP 383 Engine build thats going in my 69. Some may remember My hair pulling about the combo because of the dished pistons in the shortblock only making a 9.1 to 1 comp. ratio. I Finally decided on a set of Brodix IK200's 64cc. ,as cast . I got them yesterday , they look to be well made. I got them because I thought The Comp cc987 valve springs were set up to match a Non radical lift , Roller cam better than the other alum. Heads I looked at. The installed height is 1.875 and has 125lb seat pressure and 325lb Open. .575 Max Lift. Ill Post new Pictures later today or tomorrow.
Heres what I got.
The Bodix 200cc 64cc heads...
Edelbrock performer RPM airgap intake ( I also have a edel. performer EPS manifold laying around?).
A felpro 1094 Head gasket .015 compressed thick. I think this gasket will get the Compression Ratio up to 9.4 or maybe even 9.5 to 1 Ratio?...The gasket Is "For use with cast iron or aluminum heads." Its "Not for use on aluminum blocks."
MY Questions Are, does anyone know or have thoughts about which Cam Will make the best all around power Band For this Daily driver "TOP STREET" engine, It will "rarely" be on the track.
Im looking at these two Crane Hyd. Rollers for OEM Blocks.
1. Crane, 276/284 advertised duration,..214/222 @050.. Lift .488/.509 with 1.5 ratio rockers or .520/.542 lift using 1.6 ratio Rockers.
2.Crane, Advertised Duration 284/292, ..222/230@050...Lift .509/.528 with 1.5 ratio Rockers or .542/.563 lift using 1.6 ratio rockers.
Any Specific Knowlege from the engine pros Or Comments and info from anyone on the forum is Greatly appreciated

I would research the head gasket choice. You need something for iron block - aluminum heads.

I'm running the same heads with a Fel-Pro 1003 gasket, no problems yet

The larger cam is what GM puts in the ZZ383. 425 HP at 5400 rpm, 449 ftlbs at 4500 RPM. This was with the Fast Burn heads and a single plane manifold. GM says drop 15-20 hp with a dual plane.

Tom:
Suggest you speak direct w/ Brodix about 1094 steel shim on stock block w/ their head.
Suggest Victor Reinz gasket P/N 5746 ... thin composition ... 0.026" x 4.100" ... 5.4cc ... also ask Brodix their opinion of 5746.
Do you KNOW specs of original GMPP gasket for GMPP 383 that you're basing the bump to 9.4 - 9.5:1 on? If so ... how about please tell us what its P/N & specs are? ... NO BS, I'd like to file that info.

Its been researched , I wont be the first to use them with aluminum heads, when the maximum Bump up in compression ratio is crucial. They absolutely require a Fresh Deck surface and head surface or would probably leak.
Theres a SCE Copper Gasket Thats a 4.060 Bore and .021 thick , But the Damn Pair is $100.
Still, Im considering them. and sending the Fel-1094's Back, because I read somewhere last week, a small risk of brinneling could be an issue.
Interesting comments all..thanks..keep em comming..

All Ive been able to Find out is that The 383 has around 9.1 compression ratio when used with 64cc heads. Ill give another look though, I have the GMPP catalog.pdf file, Maybe its in there somewhere? But GMPP is notorious for not Divulging what they use and who makes it

The zz383 Shortblock has a stock Bore of 4.00" But there is a Little .030" chamfer at the deck..So Ive considered a Gasket with 4.060" bore as the Minimum size I could Use? Whats up with that, anybody Know

Looks like VR 5746 or GM 10105117 will be good choice for thin comp gaskets for use w/ Al head on 327/350/383.

[QUOTE=jackson]I looked 10105117 up in GMPP '06 cat ... it's FOR motors w/ 4.00" bore ... ie 327/350/383 ... that cannot mean gasket has a 4.00" bore or it'd burn fire ring through in a quick hurry in even a stock 4.000" bore ... gasket's bore probably 4.100"-4.166".

Yeah, couldnt be the gasket bore dia.
GM is the only one Ive ever seen list their gasket with the cylinder bore size instead Of the the gasket Bore size. Guess you can break from convention if your GM
The Fel-pro 1094 .015" thick Gasket is Rubber coated and is listed as for aluminum heads, I may use it..I want to rely on having at least 9.5 to 1 or Wont be able to get a good cam match for my needs.
and Thanks for the Copper leaking coolant comment..

I would not use a steel shim head gasket with aluminum heads, period.
Use a dynamic compression calculator on the net to calculate which cam will get you into the 8-8.5 DCR range

I am going with edelbrock hydraulic roller edl-2201.In my opinion the best cam for high performance street.D-296,300 ,L-539,548. 1800 to 6500 rpms,perfect for street .I love this cams power range.
Jegs has it advertised at 1500 to 6500 rpm

if you have those 2 choices in cams..go for the bigger one..its still not that big, but its better for a 383..you'll get probably the same performace as the ZZ383 GMPP offers. Very streetable cam, especially if you have a long gear.. What gears and tranny are you running?

Im sure the engine will be be close to 9.5 to 1 CR.
So , Advertised Duration 284/292, ..222/230@050...Lift .509/.528 with 1.5 ratio Rockers
But ..What would Happen if I increased the the lift to .542/.563 lift using 1.6 ratio rockers ?? Id still be under the Max lift of the springs ..would the power band go way up to mid and high range? Would I lose the streetability if I use 1.6 rockers?
My Gears are..
Richmond 6sp ,
3.01
1.88
1.52
1.19
1.1
and a .62 OD Gear
3.73 rear gear
I think Ill end up with the .509/.528 one but not sure about increasing the rockers to 1.6 ratio??

If you MUST have at least 9.5:1 ... Maybe you could flat-mill heads about 0.040" ... that'd drop chamber to about 59cc ... then w/ a VR 5746 it'd make almost 9.6:1 SCR.
