I am throwing in the towel. My 401 has a piston noise after all. The cover is making noise but its not the source of the "valve train" noise I am concerned about.

I'm getting a low mile 454 from a wreck for $500, building a T400 myself, and swapping a tail shaft from a Jeep T400 to use the transfer case I have in it. What aside from exhaust , custom mounts, and radiator do I need?

Last year of the carb equipped 454.

I am putting the 454 with a built Turbo400 and a tail shaft from a Jeep 400 in.

My Wagoneer will be a mutt. But I'm not the first to do this.

I know a SBC build is cheaper.

I know gas is high.

But 454 torque is what I want. My wife and I own a 30' travel trailer we will be pulling once in a while and the BBC will allow me to have a fun toy in the mud and local 4X4 park.

I want 9.5:1 compression with a healthy low to mid cam and at least 500 FT.LBS

IT WILL RUN A TRUCK AVENGER.

I don't want any computers on it. Even MSD.

Need cam, intake, and piston/head combos. I have open chamber, closed chamber, peanut, and oval ports at my disposal. As well as flat tops and dished plugs.

There are tons of stock BBC parts that I can use.
Chime in boys.

I'm ready for the herd to cut me loose over this.

If its a gen 4 block (2 piece main seals) then use 781 oval port heads. you cannot use gen 4 heads on the Gen5 one piece seal blocks (tbi motors). Peanut heads make some tq but the ovals will blow them away in both HP/tq. If you run cast pistons keep it under 5500 rpm. Go forged for towing if you can they will be less likely to melt down pulling long hills. 4 bolt blocks are great but 2 bolt with arp will hold 600plus HP without power adders, Trans brakes, and 6500 rpm launches. if your having to rebuild it I would strongly urge looking at a 496 Stroker kit. Man what happened to the 401? Stay around 9:1 compression BBC are detonation prone w iron heads. Also dont run any rectangle port head, your intake.velocity will suck until 3k then will come on like gangbusters. Great for a 2800 lb track car, chevelle w 4.56 gears and 3500 stall.

THANK YOU. I have been overwhelmed by Chevy articles and build write ups. It seems that if something works for one guy it takes some other combo for another to achieve the same results. It is a non TBI block. It was picked up by this guy because it was built the last year they produced a carb fed BBC.
I dont want redneck V-TEC so the rectangular ports are out. It seems like there is very little in between with compressions. Your either around 7-8:1 or 11-13:1 What about spending my budget on a set aluminum heads? Any brands you recommend?

Stay away from patriot. stock compression is like 7.8 to one. My 73 block has stock pistons with ported 781 ovals and roller rockers, big cam and Victor intake. Tell me what's wrong with that picture. All high rpm parts on a low compression stock short block without enough compression to set of sweaty dynamite. Can you say gutless plug Fowler without power until you hit 4k but have to shift by 5k to keep the rods inside the pan. I got it with fresh heads, new cam and lifters with intake etc for only 750. Base for my 496 stoker build. Gen 5 heads bolt up to gen 4 but the coolant passages will leak into the block and destroy it.

781 oval Ports run around 124cc so with an 18cc dome with valves reliefs will run around 9.5 to 9.85:1 that's in a 4.320 bore for a 496 on 6.385 rod and 1.280 compression height.

That.... Sounds awful on the street lol. Someone was throwing parts at a "potential" power plant. Any "RV" cam recommendations? A pleasant lump is okay but I want torque as soon as I release the brakes.

Crap... Brakes. That's another reason to swap axles. I'll need to hold all that torque back in 4-lo


Maybe stock heads will work and I can pop and intake and cam on there and get what I want. These Jeeps are very lite. More so than Tahoes, Yukons, heck even Ford Lightnings

It's got a lifter noise so I am selling ALL my AMC stuff.

I am not sure what's on it yet. I will update as I tear the 454 down. It will take a few months to get the swap done right.

I'd seriously consider it. If you can find a tail shaft for a T400 out of a FSJ you can bolt the 454 and a Chevy T400 into your existing drivetrain. I am willing to bet my MPG will stay the same and I'll gain 100 ft lbs over the 401. I'll be running a 262 cam that will net me about 350 HP and 550 ft lbs with a few mods
