Horsepower? 1973 400 cubic inch V8 Mopar / Plymouth Fury?

hmm, I was surprised to see a 400, hardly heard of it, then found a reference indicating that it is a bored 383.

Finally found a link that says either 400 cid 2 barel carb has 175 hp (california only) or 185 hp (49 state).

What is the horsepower rating of a 1973 chrysler V8 engine... 400 Cubic inches 2 barrel carb.... This is in a 1973 plymouth fury non taxi, non police use vehicle...

Can you direct me to a website with this info?...

I went to allpar but couldn't find the right page for this...

There always have been different HP ratings on the 400 and how it was built. It defiantly a "B" engine, yes the 400 had a bigger bore than the 383 but noting else was interchangeable. Allpar forgets to note this. Basically the reason for the 400 was to provide torque and HP for the bigger cars since the California and Fed emission laws were killing the HP on small block engines. The 400 was kind of a bandade thought to a weight to ratio problem. Now yes the 383 was around but was mainly for NASCAR teams to R&D before all the restriction started kicking in to keep the cars under 200+ MPH Then Chrysler came up with the "RB" engines and brought about tons of torque and HP and made the 400 look like a boat anchor.. The 400 with a 4 bbl carb, correct cam and dump that cast iron intake you can produce about 230 + HP but the parts for that engine is kind of pricey do to lack of demand. Where you would be better off with a 383 or 440

400 2 bbl is around 185 HP but has a good torque range again not as good as a 383 or 440. Plus the 400 was notorious for heating problems if the engine was ran hard. Last try this link form allpar, I know you dug around but maybe you missed this one, allpar is hard to navigate

And yes I know the difference between a B and RB block, I just brought up the 440 because I like it a lot as far as big blocks go and parts price's are good. And I had one in a older ramcharger I had and have two 440 engines in my garage ready for a 72 A-body I want to cram it in

Oh yeah it's definately possible... costs alot though... I got a buddy that has a chevy 502 big block in a 1972 nova that has been bored, stroked, blueprinted, a high lift cam, supercharger, and 2 four barrel carbs that is pushing pretty close to 1,200 horsepower... he's got about $20,000 in the engine alone..and is still street legal... totally brutal car, wheelie bars and everything.. kinda makes your heart stop for a second even when he only guns the engine at idle.

The 400 in these years was a pig. How ever, there is a lot of potential in the block. It is more rigid than the RB big block. Also beleive they had steel , rather than cst cranks. Stroker kits are avaiable to turn them into 451s an 496s. They make torque and dont have to spin too fast, which saves on exotic hi-buck parts, 6000 rpm max. Check 440source.com and musclemotors.com

For collector car info like this, I always go to the VMR Auto Guides site. In 1973, the 400 2-barrel was rated at 185 NET horsepower. Realistically, it probably makes more like 220-230 at the crank.

They were in many chrysler cars and trucks from 1972 through 1978 and were low compression and not very powerful. But, as mentioned already can be made into a powerful eng. They did all have cast cranks too. I am building one now into a 512 cubic inch, it will have GOBS of torque.
