DavyZ Posted May 20, 2001 Share Posted May 20, 2001 Well I had just purchased a new set of Comp Cams roller rockers and high performance valve springs, and when I started to pull the springs off the heads, I noticed that one of the valve guides was cracked in a big way. These heads are cast iron and are installed on the motor. I am not a happy camper right now. However, there is a silver lining in this cloud. Money can fix it... I have been looking for some aluminum heads just for fun, but now my search is serious. Ebay has had crappy results IMO with prices of aluminum heads. For example, I was following some USED Edelbrock aluminum heads until they hit $750 with 2 days to go!!! Go figure! I kinda lost interest in the motor (temporarily) since it was nearly bottoned up. Any suggestions? I wanted to spend no more than $700 for heads, but now I'm looking at about a grand for the Edelbrocks. I'll look at AFR heads, and maybe Trick Flows. I'm just not sure and not happy. A grand is more than I wanted to spend but if I buy heads, I may as well buy aluminum since that is ultimately what I want anyway. Sorry to vent, but I'm David Just for those that don't know--the 350 will have 10:1 compression with 64cc heads, the cam specs to 214/224 @ .050", Weiand Stealth intake, Edelbrock (soon to be) carb, block huggers, and high performance HEI.

Guest zfan Posted May 20, 2001 Share Posted May 20, 2001 David, Found a pair of trick flows for a sbc in a hot rod mag for 7-800.00. Dont remember where exactly but within the last two days. Will try to track down tonight and post findings. Mike Quote Link to comment Share on other sites More sharing options...

Guest zfan Posted May 21, 2001 Share Posted May 21, 2001 David, Found site. www.strokermotors.com. They list Trick Flow sbc aluminum heads for 785.00 a pair in the box. Have heard good things but have no personal experience with them myself. Hope this helps! Mike Quote Link to comment Share on other sites More sharing options...
DavyZ Posted May 21, 2001 Author Share Posted May 21, 2001 Thanks for the help, Mike. The url doesn't list a site--at least not on my computer. Hrm. Well, I'll try again at work. Gracias! David Quote Link to comment Share on other sites More sharing options...
RPMS Posted May 21, 2001 Share Posted May 21, 2001 Hey, Zfan! http://www.strokermotors.com doesn't appear to be a valid address, and a websearch didn't turn up much.

Kevin Shasteen Posted May 22, 2001 Share Posted May 22, 2001 David, Sorry to hear you're engine is experiencing the "HP Growing Pains" syndrome. Just some things to think about if you havent already considered them: 1) How do you know you're gonna obtain 10:1 comp.ratio(?)...which pistons currently reside w/in your cyl's? 2) Do you know what head gasket "compressed" thickness is required for your projected 10:1 compression? 3) Has your block been deck milled prior to your ownership; what is the piston top to block deck clearance? If your 10:1 comp.ratio is a hopeful 10:1 & the questions posed above are not known-you may find those 64cc heads putting out more than your 10:1 projected compression ratio. Hope you get your car running again: that's really a bummer-specially now that summer is here/good luck!

DavyZ Posted May 22, 2001 Author Share Posted May 22, 2001 Mike, thanks for correcting that! Now I can have a looksee! Kevin, I think the 10:1 is a hopeful 10:1. I'm going on what I have read in the magazines and such. The engine is a '72 Camaro Z28 motor which, according to my literature, has either a dismal 8.0:1 or 8.5:1 compression ratio with 76cc heads. Using a "standard" head gasket, compression should be kicked up to 9.5:1 or an optomistic 10:1 compression ratio with 64cc heads. Even not knowing the piston top block deck clearance, I believe I'm in the ballpark. 58cc heads would push me way over 10:1. I'll use premium gas with the 64cc heads anyway so I'm gonna be ok unless you compute out #'s otherwise. I'll spec the block and pistons when I take the heads off. Thanks for the help and it's good to see you around again David Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted May 22, 2001 Share Posted May 22, 2001 David, Do you know what the Intake Closing of your camshaft choice is? The actuall Seat-to-Seat not the @ .050 listing (Remember the Slider Crank Mech Thread a few months ago); if you didnt read it-go to the Misc.Tech forum & find it-should be under the heading of "Octane/Camshaft Selection" (I believe that's the forum its in) &. Anyway; I just completed the mapping of the SBC w/5.703 rods & 3.48 stroke; this will tell me what actual comp.ratio you need to run w/the cam you've chosen...just need the Intake's Seat-to-Seat closing rate from you: If it's an aftermarket cam call their tech line & ask them-then report back here, or if you still have the cam card-look on it/the Seat to Seat ratings should be listed there. Also, what do your piston tops look like (have you pulled the heads yet); are they flat tops, D-shape dished tops, two eye brow reliefs or 4 eye brow reliefs? Your piston tops & the head gasket you choose will determine what the final comp.ratio those 64cc heads put out.
