Can you pull the oil pan in the car? The part about not turning with the bar does not sound good. Maybe spun bearing?

Hopefully it's nothing too serious.

It could always be worse. Look what happened to us and racing.

You'll getter back in action I'm sure, without too much fuss.

Brand new battery from 2 weeks ago and I run an alternator but even checked battery after . You can't budge it even with a breaker bar . Have not pushed it into shop yet so not sure exactly yet

For shits and giggles, jack both back wheels off the ground, put it in neutral, and see if it will turn.

Years ago I had a 4L60E torque convertor break and internal part. You could jack it up and start it.
It was late at night by then, and I went home and got the floor jack, and a buddy we got it home around the corner by getting the RPMs up on the jack and letting it down and not stopping until I got home.

I wanted to find out what went wrong and got my convertor guy to cut it open, and a piece of metal broke off the lockup clutch and wedged it together, if memory serves correctly. It was a very small piece of metal, that I do remember.

I kinda doubt it's your problem but, it's easy to check. I had a 460 I was changing for a guy, that sat up a long time that was locked. When we pulled the heads it had a little rust in one bore. It does not take much to seeze one up. We broke a half inch breaker bar with a cheater pipe messing with it too. Had to pull the convertor with the engine. Evil or Very Mad

Brainfart, it would start in park.

If you broke the crankshaft, I think you would have felt something snap? If you broke the snout the balancer would have some play. If you broke the center you would likely have bent valves.

Easy check loosen all the rockers and stick air in the spark plug holes and listen.

Don't look good. Try to get it apart before the rust sets in too far.

That's to bad. She had a real good life and did you well though.

So are you going to stick with the Eddie's? Those Valves and springs and guides ect. do have a lot of passes on them.

It's weird as I would have bet on it but the seats appear to have no damage at all . There is althat real good divet by the flat of chamber that don't appear to be through the head but without pressure checking not 100 percent sure .

Just need to see what kind of money I will have in these heads to fix . I'd replace all the valves for piece of mind

Springs were changed towards end of last season but I need to see what I will have in them fixing and all said and done . I have been in contact with the p51 heads that guy has you posted bare heads . That is an option

Those P-51's would Complement a 528 and might put you in that 9.50 bracket easier, you were after. Not that you can't do it with the Eddies. If you are doing it on a cost benefit HP analysis wise, if you throw in porting the Eddie's it's a tough call.

Even a toned down version of this would be pretty stout with out the box heads, even with a SFT.

If I had  the spare dough, they would be gone, just to have a set.

How did the Lifter faces look, any wear?

I know there is not much upside to this but, it's good it went down in the burnout box and not down the track at a 132 MPH. The way it shut off might of kept some metal from being pumped all though the engine and also the possibility it could have snowballed further and caused, well lets just say a handling problem.

Lifters look mint I would have no problem using the cam still but going to a roller cam for the new build

That's Cool. Cool If that cam is in good shape I would keep it all in order and well oiled and stored. This BS going on with cams and lifters nowadays makes a known good running broken in deal worth more then a new one in this Bizzaro Word.

As far as the SR-71's if they are still 3K it's a interesting/hard choice sometimes.

I kind of of like the P-51's better for a car that would be more for Street Duty, Which yours is not. It's nice that you still get the 1.76" exhaust valves on the smaller bores with them, even if it does not make a big difference.
The Chambers also match the smaller bore sizes better. Also there is Hood Clearance being a 1 inch more needed with the 71's

I would run higher compression with the SR-71's over the P-51's, if I ever went with them on a smaller cube engine like a 528 to help with all that flow. Glens Deal was Sweet at 14/1 or so and it was a 552.

I would think you would be on the Throttle Stop pretty good in a 9.50 bracket also with a 528 in that League in your Ride. Very Happy That P-51 2006ish Stang went 9.16@149 after Charlie ported the heads at 3,400 lbs. or so and you are around 600lbs Lighter. Sounds like 8's might be in your Future.

We use a restrictor plate system under the carb that works well . I'm not against fixing my edelbrocks but don't want to have a ton into them vs just getting another set of heads

I have seen 3 or 4 of the Eddies come up for sale as singles lately. The last one on Ebay had the CJ port and was new in the Box, and went for high bid of $710 dollars in April and Sold. The head below is not mine and as Always Buyer be ware. Just another possible option. You may get a deal, you never know until you ask.

https://www.facebook.com/commerce/listing/756337419561825/?media_id=0&ref=share_attachment

Also if you did get a deal you would have another complete set of heads for backup or resale, even if you bought a second set. Just a thought.

i'm tempted to just do the 528 deal and weld them up and work with the eddys but not sure if its worth it . Made 652 with old combo id like to make 700-750 but solid roller and more cubes will help but not sure its going to pick up that drastic

That's a tough choice man.

If you got some good flowing heads, whether Ported Eddies, A429's, SCJ's P-51's or Stock Sr-71's and you put some compression to a 528 with the right roller cam, it's going to make more then 700-750HP.

From all the times I have seen on the Track Cars, I don't see how you won't be in the bottom of the 9's.

Hell, look at D.See's car and his weight and build along with times.

https://www.429-460.com/t282-534-ci-a429-heads-roller-drag-car-combo

Basically the same deal except for a 4.31" Crank/Piston change.

https://www.429-460.com/t631-466ci-a429-heads-roller-drag-car-combo#6196

And to Keep Things in Perespective here's 743HP 480cid SFT Mechanical Cam. Randy's A429 Headed Pulling Engine with a worked Victor Intake. No Vacuum Pump Either.

https://www.429-460.com/t25629-480-class-pulling-engine-a429-heads

You are 320lbs or so lighter. It's almost got no choice not to go faster. Cool

Ask Charlie What kind of Flow you can get from the Eddie's, I bet not much difference then the A429's. As far as Cost that's always the Deal.

Did you get the guy to budge any on the P-51's, and did they/he seem Ligit?
