Hey guys I’m planning on building my 360 into a 410 , I know there are other stroker options out that make more power but I have 428 crank on hand. Just hoping to hear some feedback from others that have converted their 360/390 into a 410 and what you think about it.
mom hoping to make a HP per cube and 450ft lb tq.

 

It’s not going to make 410hp (416hp) without aftermarket heads assuming you want to put a truck cam in it.

You should budget around $8k for your build.

 

I was planning on aftermarket heads or at least getting work done to the factory heads

 

410/428 crankshafts are hard to cone by unless there's an aftermarket company making them.
Most companies that sell them require a good core or they wont sell it.


I have a 410 in my 1976 Highboy.
It came out of a 1966 Mercury.|
I feel quite fortunate to have fond it.
It runs like a healthy 390.

 

With a 410 I think you'll fall short of your HP target.
I built around my cam and you plan to build off your 428 crankshaft so I get your I'm going 410 route as you already have one of the key parts.

I did 431ci. For pretty much the same $ you could go 445ci.

My Build info:
Stock-ish D2TEAA heads (I had some work done but retained the stock heads) Aftermarket heads will get you closer to your target.
4.080, so it's .030 over the standard 4.050 bore
Eagle Rod Stroker Kit P/N 15810 with 4032 Mahle -26cc inverted dome pistons
4.125" stroke
6.700" connecting rods
Comp Cams XE262H Grind (P/N 33-238-4) Xtreme Energy Hydraulic Flat Tappet Camshafts
1.509" O.D. Outer, .697" I.D. Inner Comp Dual Valve Springs
ProGear PG4018 Timing Chain
Pioneer 872056 Harmonic Balancer
Edelbrock Performer RPM P/N 7105 FE Intake Manifold
Now running Holley Sniper EFI
Now running Holley Sniper Hyperspark Distributor

My best dyno numbers were:

Carb
415HP @ 4400RPM
535ftlb TQ @ 3900RPM

FiTech (swapped to Sniper after 2 or so years)
415HP @ 4700RPM
530ftlb TQ @ 3700RPM

All in cost - A couple grand more than somethingclever estimated and that was pre-covid when prices were cheaper, but Los Angeles pricing, so yeah 8-11.5k is probably accurate.

 

Well let me rephrase. It will be a complete rebuild it will be bored .30 over, there will be a new cam to match the power needs, performer rpm Intake , headers, either work done to stock heads or aftermarket. I don’t have to have a HP per cube but at least 400 would be cool, to be honest I care more about torque 450ft lbs is the goal.

 

how does that power level feel I’m guessing you can just spin tires no problem haha

 

IMHO, if you want to make serious power get the Trick Flow heads instead of the Edelbrocks. I have Edelbrocks, and they’re nice pieces, but for out of the box power Trick Flows just flat out flow more. I kinda knew that going into the build since, as usual, Edelbrock heads out of the box just don’t keep up with the competition in terms of power potential output. However, my build was done at the height of the pandemic and Trick Flows were on a 9 month backorder. Now, Summit will drop them off in two days for you. My 445 did fairly well on the dyno at 440/490 and I’m happy with that, but I know I’m leaving power on the table. For once though I don’t really care. It’s not going to be making any passes at the strip.

 

Also what trick flow heads should I run? If

 

Unless you're building a 2wd street rod project or something I wouldn't get too hung up on a power goal. I have a nicely built 428 CJ in my high boy and there aren't many rigs on the road I'd call out at the track. maybe a Kia or something. big heavy awkward old pickups just aren't going to impress you at the strip, so expectations need to be low. .

 

Totally I get that and I’m not looking for a drag car just something that’s fun to drive around with good power and I can smoke the tires every now and now if I feel like haha.

 

The Power Port 175s seem to be getting rave reviews, but I’d give them a call and tell them what your goals are. I’m certain they know more than I do….. obviously.

 

Yeah those are what I was looking at not more more than edelbrock either which is great

 

Does anyone know if the CJclassics intake manifold from cjponys is comparable to the edelbrock performer rpm? I see they both support the same rom range but other than that I can’t find any info.

 

Hmm, the Merc 410.
I'm kind of thinking the Merc 410 is a tall block engine. Good for towing torque, but at the rpm where power is made.
I happen to have a '66 Merc 410 in a '71 F250 which I don't drive, and should sell.
From what I've read, the C4AE ? heads with the smaller exh ports are no Slouch for making torque.
When I'm towing, it is not flat and level, but All-Uphill, climbing up into the Sierra Nevada mountains in NE California, up to summits of 6,500 to 8,500 feet from down in the valley at 350 feet absl.
Therefore, my engine is not idling happily along flat ground in OD, but throttle plates are open and 4-bbl kicked in and running along happily at between 3,600 to 4,400 rpms depending on how long and steep the grade.
Don't forget, marine engines typically are running power-on at 4,400 rpms sustained in fast-water inboard jet boats.
So, I like your idea of the 262 Comp cam or an equivalent mid-range cam, I'm not sold on Torquer cams. just me.

My fun engine is a 385 series 429 with a D7 block casting.
This engine I sent to Auto Associates in Redding, California, and had him bore, balance, and stroke to 460.
I had him install the Crane mid-range cam and roller rockers and double valve springs. It likes to run.

I think whatever you do with your 360 will be a great improvement with the 428 crank. You'll be smiling.
