theitalian Block is at the machine shop hope to have it back next week ill post porting pics this weekend if i find time to work on the heads. Had to start with a new block the machinist bored the block a little tight last time and didn't want to do anything about it, so im using another shop for the machine work. I should be at 10:1 I did some monkey trading with a friend and he has a retro fit howards cam 232 int./236 exh at 50 0.510 int./0.533 exh lift i think i might use, it's new in the box. I'm a little over budget thats why im going to use that cam and i think it should do the trick??????..........

F-BIRD'88 You can resize and adjust the file size-resolution of your digital camera pictures
useing INfranview. batch rename etc too. a 640x480 pic fills the computer screen.

much more Web dial up IP friendly (smaller faster loading JPG files)

Infranview is a fee download.
Again thanks for the pictures. Post more as the work progresses.
The RPM heads work very good when ported. These E-Street heads should too.

F-BIRD'88 Good pics Thank you both....

I think they will respond well to porting.

ssmonty Don't know if your interested or not, but I thought i might through this out there as food for thought.
I have a set of Edel. 6073 that I played with using a Dremel with a wand. Not saying you should, but I think it worked for me well enough.
Also thought I'd mention that along with your new springs, you really need to use either a spring cup, or a locator like the Comp Cams Spring Cups pn 4694-16 to keep the springs from dancing around and chewing up the heads. By the way, they fit around the guides great without any head mods, and seem to almost snap into the bottom of the beehive spring pn 26986-16. That aren't the ones you need for the solid roller mentioned earlier, but there better than stock Edel. springs IMO.
FWIW

vinniekq2 If you used the AFR 180s,that lith\tle solid roller,A 750 HP x pumper,you would probably have a real 440 HP engine.Put 3 inch exhaust system on it some day

theitalian The easy off worked awsome but i seemed a little harsh on the aluminum
07-24-2012 09:54 PM
theitalian Got one of them cleaned up after work

F-BIRD'88 No advantage for this build, especially if you choose to go with the comp XR street roller.
07-22-2012 06:58 PM
theitalian Sounds like a hell of a combo, i have a 96 350 vortec would i be better off using that block?

F-BIRD'88 For your Z/28 Id go right to the Comp XE solid street roller cams
EG: XR274R-10 K12-770-8 or XR280R-10 K12-771-8.

A true Z/28 LT-1 with +++ street power and torque.

These cams are as quiet as hyd cam when correctly adjusted. And the lash stays.
Big power. Easy streetability. once a year valve lash done easily cold.....012" .014"
These comp XE mechanical street rollers rock.

Use 1.5:1 Scorpion/Summit/Howards roller rockers

http://www.summitracing.com/parts/CCA-K12-770-8/

The K kits are a hell of a deal.
if you want to do something reall good for your Hot Ported Edelbrock heads and either of these cams
swap the rocker studs for 7/16" and get the 7/16" rocker. 1.5:1 ratio is fine.

If the comp 1.46" springs will not sit on the spring seats its a easy quick machining upgrade you or any machne shop can perform.

Your ported E Street head motor will rock with one of these moderate Comp Mechanical Street Rollers.
