I just simply added the vent tubes to the new tank on my 70 bird. Not that hard to solder some tubes in place and connect the hose. If I remember right it was a very short run from the filler neck...

I figure anything you can do to help the combustion process is a good thing.
I've never dyno'd the change myself so can't comment, I just do it for the simple reason of trying to get the spark out...

That should get you close. I forget the cc of my 12's and don't remember how much dish was machined in the piston, that was a couple decades ago, I'd have to find some paperwork. I want to say 13cc...

If you end up machining a dish you'll need those forged units. $7-800 for a set honestly doesn't sound horrible given the prices these days.

I use the regular 3924's. The AR's just have the ground strap cut back over the center of the electrode.

Yeah Jay, oil is always a weird subject with people. Someone on the internet always says this or that is better yet almost no one even sends off a sample to see what their oil is doing.

I'd be inclined to leave it alone at least until you dig into the current cam and find out what it is first.

If you really want to change the cam it makes more sense to leave it a roller so you...

That's a good question Bill. I would say likely a lot more than we hear about as most of these threads go unresolved or people are reluctant to admit any fault and blame the cam and/or lifters. ...

Yeah Bill but you also found springs that only had 80 lbs. on the seats. I wouldn't call that a cam and lifter failure, that was just the result.

They use Johnson bodies which is good quality to start with. And with the lube option it's about as good as a flat tappet gets. Nitride the cam on top of that and it's a pretty solid setup. I don't...

I've never found any need to modify the coolant passage for heater cores on E heads, or any other brand for that matter, never blown a heater core.

But if you have extra time and really feel...

Honestly if you're going 121-123 mph, that car should already be in the 10's. That's easy 10.80's with a decent short time. That tells me that your short time is lacking and most likely the biggest...

That's really what it boils down to for me. As much as these engines cost these days to build them right and use top notch parts, it's not a hard decision to just put a good rocker arm on it. Budget...
