I wouldn't want to touch that either. But there's tons of people that live on the coast (all three) and in the salt belt that drive cars like that every day. I know I used to see cars like that in Oxnard when we'd visit every year.

mark1305 My father lived in Fernandina Beach and on the beachfront for many years before moving inland to the middle of the island. His "beach car" like so many folks had back then was a 1958 English Ford. Nowhere near that kind of rust even though it literally was only driven on the beach. Learned to drive in it on the beach at age 13. Four speed stick on the column. Now that I think about it I picked up a 1958 Mercedes 220S (gas) in 1980 while stationed in Miami - four speed on the column. Odd coincidence.

Living in PA, I feel for this guy. I own vehicles in that condition and have repaired many.

fishadventure I’d venture out and say porting a 4.0 head is good for 50HP- and much more- but not by itself.
An apple pie takes the same amount of apples if made without spices, but add a little sugar, cinnamon, allspice, cloves, and flour and it tastes fantastic. It’s a system of flavor.

Analogously, head work doesn’t give the whole possible ‘pop’ without great attention to the other six or seven engineering items. Which is why variations on a basic 4.6- 4.7-liter stroker are only 250-290HP generally. The sum of the horsepower gains each can provide individually is far less than when all are fore thought and implemented together.

Why do a 4.0 when your favorite whirlpool or black-and-decker V8 is ‘cheaper?’
I like almost everything about an in-line six. The reliability is superb. It’s easy to work on. It’s dependable. And even when bad mechanical things happen inside it often will continue a long time as long as it has oil pressure and coolant.

I may “truck out” a YJ at some point and heavy-duty it, give it a 360 AMC V8 for towing. Someday. Retro looking. Lots of brake. But jeeps are fine with a six or even a four. Do a V8 if that’s your thing but don’t try to justify it by broken logic reliability rationalizations 🙂

That's true, but there are reasons why you'd want to keep the 4.0. I'd probably swap a 350 or a 323 in if it was me.

You need the heads, valves, cam, exhaust, etc. to flow the additional amount of air introduced into the engine, and at a point a compression change.

One thing that leads to a good running and good throttle response it good manifold vacuum. When you put to big of an intake or carbs or both onto an engine you kill its manifold vacuum. Carbs need good vacuum signals to work correctly. All engines need to maximize intake vacuum. Good vacuum keeps air velocity up high.

Their claims are simply impossible.
I agree that their claims are spectacular, but they aren't the only company that sells a similar product and makes similar claims.

However, all the information I have seen on the 4.0 makes it sound like the head is the limiting factor, not the intake. You can grind the intake and exhaust ports on some of these heads and make better flow, which sometimes gives you a pretty good performance boost.

Long story short, yes, I know it is improbable. But Chris has money to burn and I like to make jokes.

-----------------

In other news, my Form 4 got approved three weeks ago! Just waiting on the ATF to pop the stamp in the mail!
EDIT: For those wondering, that's a 4-month approval time. Stamp was purchased 4-27-20, approved 9-11-20. I guess it pays not to have a record.

They claim it more than doubles power.

It's a Pat Musi Racing Engine. The owner said it would pass everything but a gas station.

DROOL....

Plus all the little rotating assembly balancing eliminates cyclic power reductions and mechanical losses. EFI tuning optimizes the mixture for maximum potential at any given rpm. Horsepower doesn’t just happen by adding fuel.

Getting 250hp with a 4.0 is slightly easy. 300 takes quite a bit more work and dollars. 350 gets expensive, and that 400hp is almost dreamy.

What a nice power curve chart though. In an I6 I bet that feels meatier than a V8!

Since I wear Dad jeans i'm good to go. I have a "sticky" holster but can't stand to leave my shirts untucked. My setup fits neatly in either front pocket. I use a small tape measure to disguise the shape of what is in my pocket

bruinjeeper That time of year again... free hardtops lol.

This is like 3$ USD.

Use the change saved on some Krylon satin black, MEK and scotch bright pads

If I'm wearing a loose-fitting T-shirt you can't see much, but I normally wear collared shirts, so I have to leave them untucked to hide the gun. So I don't usually bother trying to conceal it.
