Think I had to use some helicoil to hold in some shocks on the Vette. Great stuff.

I really wish AFR would have done that on these because I've also had to switch the heads f ok the sides I normally run them on. The one I use to have on the drivers side has stripped the accessory holes so it is now on the passenger side.

I agree Ben they are great.

I finished up the Cobra last night and took it for a test drive. It ran great but when I got home I noticed oil dripping under the car from the back of the engine. After looking it over it looks like it's coming from the rear of the intake manifold. I must not have built the silicone up enough to seal it. Now I have to pull the intake off and fix it. Hopefully I can get it done today.

I noticed I usually have to let the silicone dry over night or it leaks.

I've never waited for it to dry overnight and never had an issue. I think I got a bad tube because it was still wet when I pulled the intake off this morning. I'm glad that it did leak though because I found that the lower part of the lower intake gaskets are leaking. The bottom of both sides were wet and the intake track on the heads was wet with oil. If that was happening before that might be the cause of the light throttle miss I've had. This time I used silicone on the intake gaskets around all of the intake ports. I normally do that around the water jackets only but this time I did everything. I'm also letting it dry overnight. I did start it after letting it dry for about 3 hours but just so I could move the car.

So updates to this thread. This build always burned oil, I'm not sure why but it did. Well after a couple of years it started to get blowby as well so I decided to pull it apart to see why. I couldn't really find a reason for it but I think the intake gaskets have been leaking the entire time. I was just going to re-ring it but I found a couple of cracks in the block so I started all over with another block that I already had.

The build is the same as before just with the custom cam that I had done before instead of the Comp cam I'd been using. Since I was doing it all fresh I let my kids pick the color for the engine and then we did a raffle to see who won. My younger daughter Mya won with VHT Burnt Metalic Copper. So I took my time and cleaned and painted everything. I only have 50 miles on it but it doesn't have that burnt oil smell it used to. I need to pick up a new harmonic balancer for it because the one on it is bad so it's just sitting until I can get that.

I'm curious to see what that cam does with the 347, because it made stupid power in mine.

Hopefully I find out here in a month or two.

That's tight. Looking to see what you get.

I'm not going to synonym it again. It runs good so there's no need. I also hooked up my methanol injection so the next time I take it to the track I should be able to run on 91.
