401 swap update. HP estimates break in Q's too.

Finally Had some good weather. Got the 401 painted up and assembled.

I got it mated yesterday before I called it quits before sundown.

Feel free to chime in. I have a lot invested here

From what I understand on a new engine you prime the pump with old dizzy.
Use oil with zinc.
Just to be safe add octane boost to the tank of regular unleaded because it's 9.5:1 ratio.
Run 20 minutes between 2,000-3,500 RPM
Drain oil and replace filter.
Drive up some steep grades. In the few thousand miles to set rings (TRUE?)

When can I go do a dyno pull?

Or do you think I met my goal of 400HP 450ft/lbs?

MSD coil, dizzy, and wires
Edelbrock Performer intake
670cfm Holley TA ( do I need more carb?
.30 over
9.5:1 plugs
5-angle valve job porting too
Crower stage 2/3 cam
INT/EXH - Dur @ .050” Lift: 212/220 RR: 1.6/1.6 Gross Lift: .464”/.488” LSA: 112 RPM: 1500 to 4500 Redline: 5000

I've been asking around a few other threads and the only answer I got was 350HP

What else could I do to have a street able 400HP?

I find it interesting that the HP ratings for the 401, in 1971, were 330HP @ 5000 RPM and 9.5:1 compression, stock.
In 1977 that number went down to 195HP @3500 RPM and 8.25:1 compression. So whats the real base HP rating of the stock 401?

SAE vs NET rating system. Run a high zinc oil like Joe Gibbs driven or Brad Penn the parts store crap w additive won't be enough. Run that less than 400 miles then swap it to a longer duration non break in but still high zinc zddp.

I got a case of CompCams break in oil. Thanks for the info.

Captainak- can you give me some of your specs on your build or is it close to mine?
And how long did you run it after break in before you did a dyno pull?

That is some impressive power by the way.

U had mine built from CMEngines in NC ...... I really don't know much about my build except that I was first 401 they've done as they do exclusive 360 and 304 for racing..... It's 10:1 compression, choppy idle and has oiling mods..... Doesn't have roller rockers but I was told it would put another 15-20 HP ...... I figured I already had 6500 in the build ..... It was dyno'd with the edlebrock thunder series I have on my old 304 and it didn't pass specs so it now has a Quick Fuel Tech VS 680 on it and is very responsive ..... Running Holley blue eletric fuel pump

I'll see if I can get more info

Wow. I actually looked at the dyno chart closely this time and 485ft/lbs at 3500-4500 is impressive. I was going to ask if your running a stall converter but with that much torque in the lower RPM's you probably don't need it.
I'm sure rollers and a bigger carb could make you some more easy.
If you could share more specs I'd appreciate it.

I threw an email to them ..... All I have is a receipt with pretty much no details .....

The following is why I didn't worry about details ....

"CAROLINA MACHINE ENGINES for over 28 years has hand built over 50,000 Remanufactured Automobile and Marine engines, also Street Performance Pump Gas Crate engines and World Champion Racing engines. Sold at 'Factory Direct' prices. Our 'Better Business Bureau' rating is A+ , their highest rating available."


CAROLINA MACHINE ENGINES is an expert at extracting the most horsepower and producing the most dependable High Performance Pump Gas street engines available. We are able to do this because of our long time involvement in racing and performance street rodding 'and' because of our experience as a Production Engine Remanufacturer (PER).

Although we produce "high end" Performance and Race engines with expensive parts, we also produce more economical engines that use one or more of the stock OE parts such as block, crank, rods, heads, oil pan, etc. These engines can produce amazing horsepower and give good long service when "done right". We have the ability to accomplish this because of knowledge and experience gained from decades of racing under basically "stock" type rules and regulations of the various sanctioning organizations.

Each of our engines receive all new high Quality internal components, including performance valves, forged or hypereutectic pistons(when available), moly rings, brass expansion plugs, premium rod and main bearings, cam bearings, pushrods, valve springs, rocker studs, hydraulic lifters, rocker arms, timing chain set, and a specially chosen and dyno proven performance camshaft.

We use the highest quality brand parts such as ACL, B&B, BULLET, COMP CAMS, CLEVITE, CLOYES, DURA-BOND, EAGLE, EDELBROCK, ELGIN, FEDERAL MOGUL, FEL-PRO, HASTINGS, HOLLEY, JESEL, K-LINE, LUNATI, MAHLE, MANLEY, MELLING, PERFECT CIRCLE, PIONEER, PROBE, RHS (Racing Head Service), SCAT, SEALED POWER (Speed-Pro), STEF'S, SILVOLITE, STERLING, US SEAL, US TOOL, VICTOR-REINZ & WEIAND.

Many people make their final choice based on the vacuum and idle characteristics of the engine. See the "Idle Type" column above with the engine pricing.


"CHOPPY" idle is a very noticeable performance idle and will have a somewhat lower manifold vacuum, 10 to 12 inches. We recommend quality headers and a torque converter in the 1800 to 2800 RPM range. This is basically a rougher "Muscle Car" idle. We define these engines as "Almost Daily Drivers".

You might have 400hp at the crank, but you'll never really be sure if you're going to do a chassis dyno pull. Looks more like the 350-375 range to me. If it isn't there you'll probably have to do more extensive head work, with possibly a cam change. Think airflow and friction reduction, which is expensive.

What's more important than a number is the smile on your face you'll get when you feel the amount of torque the 401 makes and the big RPM range that it makes it in.

I guess the torque really is what matters off the line.
I convinced my fiance to let us drive the Wag down to South Texas this summer for our honeymoon.
I really just want my soon to be wife to be stuck to her seat when I punch it and pass people on the freeway with confidence

Captain- they didn't give cam card info, head work done, intake used, oiling mods, porting done?
Not to be rude but that email was just telling you the do's/dont's of your build. Not the actual specifications and recipe used.
With that much money invested I would want to know. Maybe that's just me.

I'm a word of mouth and end results guy ..... Not really into the particulars of the build... As I know a lot of people are..... I knew from my military jeeper circles that these guys produce quality and all I was asked when I called was how much HP (375-500) I wanted ...... Guess Im not much a a detail guy...... But still wish I had the info to pass along lol ..... Sorry
She is pretty though

Thanks anyways.

That's thing looks slick.

Love the serpentine set-up and alternator bracket.

I think the only performance part you have that I do is the dizzy lol
