Gotta love it!
Good thing it was only eighth mile. Was it just one bearing or all of them? I would torque all the rods down and run a bore gauge through them. A early hemi can rpm higher than a 426. I would personally feel more comfortable knowing the big end of the rod didn't go out of round.
Yeah it was a damn close call. The oil pressure went to 30psi right at the return road and the engine died. Its downhill to the trailer so it wasn't started until we got home. We started doing a leakdown test and the damn thing was 90% stuck! The starter could rotate it but the crank bolt wouldn't budge it. Another 1/8th mile would have scattered it.
So the rod bearing closest to the pump was fine. All the mains are like new. Each bearing going farther from the oil pump is blacker. Johnny is checking the rods and fitting the bearings today.
Race cars .......
The old rule of thumb for oil pressure requirement was 10 psi per thousand RPM. Recently I've been hearing that that rule of thumb is obsolete and excessive. It looks like your experience proves that it's true
i see you changed the spring in the pump. my missle pump had a adjusting screw on the outside. i dont recall steve ever mentioning a different spring being available.
Sometimes I feel like Hot Rods/Race Cars are an exercise in masochism.
Yeah he wasn’t keen on me changing the spring but said it’s possible. My theory on this - his spring is 36# and I swapped it to 27# . At idle or just using a drill it went to 80 psi fine. At 9000 it might be doing something weird. Happened too fast so maybe it was fine - don’t know. Don’t mess with success.
Johnny said the high dollar crank paid off this time. Polished right up. A stock crank would have been scored pretty bad he said.
$100 fitted bearings
Cool. You get what you pay for. Nothing like quality parts. With the drill the oil was cold right? Cut that by half hot.
Now you have the hair raising on the back of my neck
Is this any relation to you?
That's awesome. I can't wait for an autographed q and d.

What town was that dealer in?
I am a Turner too.
Found the picture on vintage shots from days gone by thread, no info
Oh okay. Pretty cool. Recently found out my great grandfather was American, from Erving Mass. So I've been trying to find more info. Thanks for the pic
You might try google search the picture and see what it turns up
I wish - maybe get a discount. That’s a cool photo.
Got the car almost ready again for Saturday. 27 cars in A/G alone.
Great save on the engine! Have an Outstanding race, Carp.
If it wasn’t for bad luck ...... glad we caught it in time to just need a polish.
with those clearances you might want to step up to 50wt. or 60wt. I really like the lucas race oil. if you cant find the race oil the regular will work with the race additive.
Cough... cough.. accusump...cough.

That's the same clearance I run, and I use 20w50 VR1. No issues there. If it's a little loose, only you will know. If t's a little tight, everyone will know.
Yeah 20W-50W Lucas in it now. Good talking with you the other night - I looked up that drag strip and it looks like 8 hours. Hope to add this to the list.
What the hell is that?
I lost several bearings and even engines until I went with this. If you must run a wet sump oil system (SEGA legal) this is the only way you can make them live in my opinion. It smoothes out the oil pressure so that your oil pressure gauge looks like an electric gauge instead of the bouncing needle that you usually get with a large line to the gauge. No more small gulps of air. Call me if you have questions.
Yes it was fun talking hemis. For everyone Tony is talking about going to George Ray's wildcat hot rod drag strip in paragold Arkansas. There is a thread on it for the may 19th race. Look up George Ray's on the hamb.
Racer, that is Quite a story/history. Thanks for sharing it!
That Accu-Sump system Rusty provided a link for on Canton Racing would be valuable insurance for an engine which encounters the G- forces present in the SEGA Gassers. Sure, you can baffle a pan and this does help IF the baffles are placed just right. But how do you KNOW they are right?
If you could somehow set up an instant reading and recording device on the oil pressure in an "A Gasser" I'm willing to bet it would scare the shit outta you when you see the dips and surges in the oil pressure. And the cost, while a few hundred bucks, is peanuts when compared to the cost of the engine.
Another Accu Sump benefit is that properly valved and plumbed you can use it to give the engine oil galleys a couple of quarts as a pre oil before the engine turns a single revolution after it has sat idle for days, instead of firing off and the oil pump trying to pump that cold, thick oil up into the engine.
If I had spent the kind of coin it takes to build an engine that's competitive in SEGA, I would take a serious look at the Accu-Sump system.
When I was having trouble a few years ago, I talked to Canton about building a custom pan because of the wheel stands. He listened to me then sighed and said he has this same conversation several times a week. He said that the tire, braking, and power technology has run away from being able to baffle a wet sump pan to work in every direction. Plus the fact that everyone is going to thinner oils it is impossible to keep the pick up covered in oil all the time. Look at the OEMs. All the fast cars are dry sump from the factory now. Do you really think they would add that cost and complexity if it wasnt the only way to make it live? Sticky tracks, good tires, high rpm manual launch with the wheels on the air and the oil is pressed up against the back of the engine and possibly splashed up against the top with the crank whipping it. Then the opposite happens when you get on the brakes at the top end.
Put a 3 quart accumulator on it and forget about it. Plus I use it to pre-oil the engine before every cold start. It even holds oil pressure in the tank over the winter.

I had forgotten about them, Rusty. Used to run one years ago. Your reply reminded me of this and I ordered another one to be here tomorrow.
Now I have to find the space to mount one. Sure sounds like an engine saver
Well that spiraled out of control. Looking at the forecast for last weekend, @3dnsouth calls and talked me into going to Austin Texas - truly a wildman
