Man I like how you think lol

 

That's fine if you see your car as a drag car only. And perhaps Darth does, given his (F'ing awesome) ~700 HP engine. It's an F body with a solid axle rear end.

I'd never do that to my Miata. It's intended to turn corners, and it wouldn't turn corners on giant drag slicks. I know I give up straight line capability (I'm on 225 street radials, LOL), but I don't care.

 

Guys thank you for all the kind words. Both very humbling and very much appreciated. There is so much to reply to and yest, to try would just be a multiquote from hell. I had to catch up on stuff around the house, so I have pretty much parked it since Friday evening. Got family coming over today. Life steps in, etc.

To answer the big question, next steps -- I really need to get the intake off and see what's going on in port 3. Tony's choo-choo-train comment is not far off actually. I put a vid on here from day 1 when we were trying to handle some weird breaking up at 2800 it wants to do. I stepped out of the car and the guy held it at that spot. My hope is it is nothing but an epoxy failure and I can re-epoxy it and it holds better. We will see, anyway. But it sucks to drive and then your clothes smell like burnt oil the rest of the day, so I gotta fix that before I do much else. It's also impossible to tell what is ring seal and what is leaking in.

I also put a vid in that everyone wants to se. Pull #6 from day 1. You can tell at the end of the pull, it was still pulling hard. I drove all the dynos day 2, and I was preoccupied with trying to make equipment changes quickly since I was paying by the hour. But anyway, enjoy!

 

Yup she's burning oil alright...

 

Maybe just missed/forgot to silicone the rocker bolt for that port?

 

Do these heads have a through bolt into intake port from rocker arms?

 

My car did the exact same thing on the first 2 pulls. On the third pull it was just like someone hit a switch and the smoke just quit instantly and never returned. I was a little worried at first though for sure.

 

I was kind of being coy about it, since I am 95% sure what the issue is. But I was holding out hope it was something else. So set the way-back machine to something like 600 posts ago when I tried to start the motor when it was a used 428 with only a heads-can-intake swap.

If everyone remembers I missed the lifter cut with the pushrod, bent the rod, bound up and broke the link bar, spun the lifter, and the busted link bar punched a hole in the intake runner from underneath. All that happened on number 6.

We epoxied it, and my fear is the early overheat issue I was having after THIS first start caused the epoxy patch to fail. I moved the head to driver side because on a F car that is the easier side. Which means the epoxy patch would be on 3, which is the one that is oil fouling in a single pull.

I was going to wait until I got the intake off to confirm it and post knowledge vs speculation but thought I would at least remind everyone what happened before.

Here's how #3 looked every pull even after putting a brand new plug in.

 

Well i sure hope you are correct and you sure as hell are more patient then me when it comes to wanting to know lol

 

So I'm not the only one who thinks it's extremely nerve racking putting pushrods in the engine while is in the car?

 

Great results mate....You'd have to be happy
Why epoxy the head. Just weld it and be done with it.....

 

Thats the problem with repairs like that. Always seems 50/50 and will be in the back of your mind forever. I for sure would have bought a new head knowing I just dont get lucky like that. But hey, he took a shot. At least Jake is transparent and we ll 100% know for sure soon.

 

Good luck with your investigation next week here. BTW your 7,000 rpm torque is 90% of your 5,000 rpm tq which is outstanding (480/530 - I am going off your 650 hp run), the later ones were even better.

 

Sometimes numbness comes over as patience. This was such a hard build, and I REALLY don't want to pull the head off. I mean REALLY.

Not at all. I hate it. I'm always afraid I'm going to drop the pushrod into the galley and have to pull the heads back off.

We wanted to. Couldn't get both the electrode and the fill metal in there. Kind of in a bad spot. I'm actually considering drilling the hole out bigger, tapping for a MIP plug, epoxying the threads, running a plug in there, and then grinding it smooth with the port.

I hear you, but so much one-off stuff went into these heads, I'd pay in one head what most pay for two. Trying to salvage it any way I can.

I was stoked at the torque curve. I was surprised at how the tires changed the torque curve on the second day. That was really neat to see first hand.

 

This is the route that I would take if you can get a drill and tap in there, then stall a brass plug and grind.

 

No but I have done standard compression tests and all holes are within 5 psi of 200. Motor is actually sealing up.

 

I just went through something similar with high temp JB weld melting away lol.

 

TIG welder

 

.....

 

Mig is the only hope and it will be a **** show....... as far as welding it goes
