    Got my motor apart. Doesn't look to bad in there. worried image

    I know I have a detonation problem and found a little evidence on two rod bearings. No biggie, I've been trouble shooting it for a while. Believe I have to much compression and workin' on my timing curve for the junk they sale as gas these days. Already have the wheels in motion to remedy that. biggrin image

    But what I've been thinking for a while now........my heads are junk. bawling image I will investigate further to verify. They came off a motor that sat outside for years. I think they sat for just a bit to long. For right now, I don't have a choice but bolt them back on for the run. weepy image

    But on a positive note, I did find my clutch problem A broken throw out bearing. Came out in two pieces. Only 14k miles on it too. banghead image

    One way or another, we'll see Ya in Florida.

    Something to think about on the timing curve--after fooling with one for 2 years. I was getting detonation on high rpms at part throttle (i.e. cruising at 3500 or better). The GTO still has 10.75 compression with a '67 HO cam and an MSD distributor. I was able to leave in a good initial timing and run a normal ramp by swapping the bushing that limits the max advance. High Performance Pontiac had a great timing article in the archives on its web site.

    What's with the heads? If nothing else think about new valve springs.

    Hey Mark, great deals on ebay for pontiac cylinder heads my bud(brotherchum) just won a set of 64 heads same as I use for under 100bucks plus more for shipping, but in really good shape, I believe a few weeks ago a set of 62heads went for 400.00 plus, only draw back on the 64heads is you must use gto/firebird exhaust manifold . unless you drill and tap a hole on each end of the outter ports...and on your engine, what type of carb are you running, and is it jetted correct, the "mean is lean": term may be coming into play on your engine, allowing it to spark rattle, increasing the fuel enrichment(to cool the cylinders) will help, also ,with todays fuels, I always run a can of 104 octane boost to a tank of gas.helps out to a degree.I am sure you knew this already, but just thought I would throw in my 2 cents.....I am currently building 2 400s,one with a set of 4x heads and a 4speed engine with the 64heads, I have numerous 6x heads, if you need some, along with some 301 heads... eek image get er done..

    Thanks guys.

    We can talk on the run. To much to type here.

    Stan, I believe Rocky wrote that article. He's the one that set up the dist that's in my car now.

    Mark, We can talk about a set of 6X's then too.

    Good luck on the engine. I know it's tough when it's all in pieces and the pieces don't look good----got to go paint engine parts, the GTO is getting a new water pump, timing chain cover, and an engine repaint so parts are all over the garage.
    Pam can't get her car in the garage (all of mine are tucked away inside). Life won't be good if I don't finish before it snows again.

    Thanks Stan,


    No worries though, the motor will be fine for the run. I just hate to put those heads back on it. I'm not 100% positive their actually bad. But things point their way. Gonna have them looked over. It's not like their gonna kill it. I just don't have time (May is coming quick) or money to get a set done up right now.

    I have a ton of other things I need to do. I want to ceramic coat the heads, intake, pistons and headers. Plus I'm gonna coat the trans too. I have a heat transfer coating thats works great. Sprayed my radiator, car runs 15* cooler.

    Good luck on your project, keep the faith baby. wink image
