See the groove.

Most of the aftermarket rockers have a groove around the inside. This negates the need for a banana groove. I wouldn’t condemn your rockers. If the shafts are pretty worn, maybe new shafts. None of this equates to you oil question. Don’t want to scare you, but having a rocker seize to a shaft...

These are the banana grooves. Kinda funny that I searched banana groove shaft and the picture to the left is my toasted rocker.. :):)

I had one that acted funky brand new. Replaced it and no issues. It was inconsistent on holding power.

The notches are an indicator of the location of the oil holes. Know the orientation of the oil holes themselves and you KNOW they are correct. If the oil holes are down and biased towards the springs they are correct. You don’t have to worry if your notch is a real notch or the notch was machine...

Remember the shaft is upside down in the picture, but the arrow points to valve springs.

So you see how the bolt holes are not inline with the oil holes? You want the oil holes down and more towards the valve springs.

So, a note of caution, when you put it back together. Make sure the pushrods are seated in the center of the lifter. Due to the small blocks crazy lifter angle, you can have the pushrod sitting were the lifter body and plunger meet. Off center, that can hold the valve open or it reduces your...

Pretty sure it is controlling the car by blocking pressure from the rear. This is why it is inconsistent. The holding force is only what your foot is applying and you aren’t applying it enough. Try and push the button then drive it like it doesn’t have a line lock. Apply all the pedal pressure...

The shafts could have drained back, so it needs to fill the shafts again. No downside to just spinning the oil pump and just turn the crank 5 degrees at a time, look for oil. Give it a second each time. Repeat. Remember you need two full crank revolutions.

One thing that can happen is if you run this up in rpm. The smaller water pump pulley can spin fast enough to cause cavitation which will erode the front cover. I have had it happen. I have the original A/C water pump pulley (small) and spin it to 6500-6800 rpm. Put an anti cavitation plate on...

I have not been to a track that doesn’t require and overflow can. I have run closed end lug nuts forever, but always on a steel wheel. If you have sufficient engagement they might make you pull off a nut to show it. I have a loop, never had someone look for it.

I run that exact oil, have forever. I’m sure I’m leaving HP on the table with it, but it’s working for me.

This is something that I have thought about a bit. As crazy as it sounds, my cars setup really leans towards a radial style. The sidewall of the redline is pretty stiff and a radial car is usually under tired for the power level. I haven’t been able to dynamically test my therory, but I did...

I’m curious as to why it’s better. Is it because you are actually using the sidewall as tread or the change in sidewall angle might make the sidewall less rigid vertically? It must take a higher tire pressure?

So the belts you have are 7480 and 7370. The first 7 is the width of the belt, the last three numbers are the length. 48” and 37”. If they are 4” too long go buy a 7440 and 7330. If the number is 7485 it is 48.5” long. There are a number of water pump pulley dia. A/C, non A/C etc.

When it dies, will it start right up clean or does it misbehave a bit on start up. Start up clean it probably was lean. Misbehaves and it is having to burn the raw fuel off the plugs. I REALLY like running an AFR gauge in a car. When the car has an issue. The gauge will quickly reduce the number...

The kick down lever should be all the way back on the transmission when you are at WOT. It shouldn’t hammer the linkage, but should be fully back.

Pinion snubber was a cheap solution to a problem that is much easier and better solved differently now a days. A snubber is just too violent. Shocks are just so much better at controlling axle movement. You give me a “snubber” that uses an adjustable small shock and I would play around with it...

Definitely had door panels to start at least. I always planned on taking more pictures of it, but not my car or shop. Was very nice getting a chance to see an original one. :)

Play with tire pressures. Spin the tire in the street, you want an even color all the way across. Dark outer edges? Add 2 lbs. Dark center? Lower 2 lbs. Continue until it is even.

Unless you have seriously old rear springs, just leave them alone. The front A body spring section is so short, you really need a bunch of power and a sticky tire to get wheel hop. My advice is to avoid the puddles that form in front of the burn out box. Line up a bit offset. Don’t spin the tire...

A mixture of driver side timing tab and 68 water pump is not that bad as long as the balancer has marks for the driver side tab. If you find it a problem to see the marks. Just get it to TDC, then make or find a bolt on passenger side pointer. Then install timing tape.

I have the MB clutch unit IIRC. Running it with a 68 pump. 3/4” from the original 340 A/C radiator.

I think you’re running into “trying to get back to 10.5” it probably never was 10.5, higher that other LA’s? Yes, true 10.5 probably not. The deck heights are usually higher than spec. How far in the hole are your pistons. I would lean towards the cometics. Probably overkill, but the lack of a...

Are you SURE what you found is for an LA small block? Most of the clutches have slots. So unless the slots are not spaced equally, it should fit most water pump bolt patterns. I actually don’t think there are different patterns though.

I was thinking about ceramic coating my exhaust manifolds to cut down on under hood temps. Looking at the claims on the websites, it seemed reasonable. I know someone who did just that. Inside and out. IR temp gun says it’s a waste of time in regards to heat control. 5 degrees of decrease in...

I was required to run a “race” tire on drag week. It was the only 14” that would work.

In competition I have to run this tire. Testing I run the M&H

In competition F70-14 redline lines, last week testing was a 14” M&H DOT Musclecar tire. My limited converter flash, (3500) doesn’t let me use all the M&H tires ability. Which works out just fine for me. More apples to apples, just more repeatable.
