410 vs 428 Power Difference
« on: December 30, 2021, 09:18:59 AM »
Maybe I missed it or don't remember if this has been addressed but, all things being equal in the build (heads, intake, camshaft, compression etc.) would there be any measurable power/torque advantage with the extra 18 cubic inches of the 428 over the 410? Would it even be noticeable in a street vehicle?

Must be winter time, what with the rhetorical questions and all.  ;D

Thanks guys.

I took a 1963 352 block and bored it out to 4.05", added an Eagle 428 crank and rods w/Edelbrock heads, Edelbrock RPM intake and Holly 750 carburetor along with a Cam Research 282/288 cam and 9.9 CR, Stan Johnson headers and 3.50 True Trac. Put it in a 4300 lb car and went 14.25 sec through the quarter mile on street tires. Granted a lot was lost on traction but I don't think a 428 in stock configuration and street tires could do better.

Bruce, I doubt that you would notice much of a difference in the car, but the HP and torque numbers of the 428 would be up by at least 15-20 over the 410.  Cubic inches will always get you some more, especially on a street vehicle.

Most streetable FE's hit somewhere anywhere from 1 hp/ci to 1.3 hp/ci depending on the build.  So, 18 cubes difference could be 18 hp or it could be 23 hp.  May be noticeable, may not be.   A Super Sucker could get you the 20 hp though....

Jay: too bad your book didn't compare some more base engines like a stock 390 GT and a 428CJ. Then the manifolds might make a great difference, or maybe not?

Excellent, thanks guys.
Jay and Brent, really appreciate the technical data.  8)

I've been throwing around the idea of using my '62 352 block and boring it to 4.05 (it's 4.03 now) and building a 410 or waiting on a 428 block I'm purchasing from a forum member.
He said he'd deliver it to me when he came down this way but it could be a while before that happens.

Anyhow, that was kind of my reason for asking the question.

Using a 352/390 block is a lot more cost efficient.  I'm going to put my flame suit on and then say this, but for the price of a 428 block these days, I really don't see enough difference in power between the 428 based engines and the 390 based engines to justify it.  Even an A scratch or industrial 428 block is stupid expensive these days.

Awesome Brent. Thank you for your honesty.  8)

I may just build the 352 block then. I have verbally stated to the gentleman I want the 428 block and I will not go back on my word, so I'll be getting the 428. The car still needs a lot of work before it's ready for an engine and the 428 block may arrive in time to be used anyway.  :)


Either way, I'm very happy with the responses here. Really appreciate it, guys.  8)

Some of the old 352 blocks have thick cores. It could be taken out to 4.13 bore if it is checked first.

I did a quick random check on a few cylinders on the 352 block with my handy dandy $130.00 ebay tester and it appeared to be pretty meaty. Can't recall if it was 428 bore meaty or not. Will do an in-depth check when I disassemble it the rest of the way.

Thanks.

Keeping the cylinder walls thick will serve you better.

Years ago I think Jim Dove (if I'm not mistaken) wrote an article on building the FE engines. In it he stated that the pre-64 FE blocks were a bit beefier than the later blocks. I mentioned it once and the guru's on FE Fanatics shot me down. So, I don't know if they were or weren't. The only thing I know was I read it from a reputable source I thought at the time.

I'm going the 390 route also. No time table for me so I'd have used a 428 block if I had one. The cost of a used 428 block is about halfway to a new aftermarket one. For me, costs just spiral up too much for street car applications. My 390 mirror 105 block was almost free by comparison. I got lucky though.

I'd tend to think the lack of bolt on high horsepower heads/intake made getting every cubic inch very important. Porting can do wonders but at an additional cost. Jay's heads may prove to be the missing link as they should not be the limiting factor. Hopefully we don't turn too many 390 blocks into boat anchors in the process...

The '66 factory specs were: 410 - 444 ft pounds of torque, 330 HP;  428 - 462 ft pounds of torque, 345 HP.  Same cam, heads, carb size, etc.

SAME HERE JUST DIFFERENT it was not Dove,someone different.when i was a teen and early 20s, i was living,eating,breathing,sleeping,dreaming,FE engines back in the early 80s.i read an article that said 66-c6me blocks were the best bar none,the c6me-a weren't bad is how i remember it quoted.and the same article had a pic of dozens of FE blocks lined up in rows on the floor. and also i got shot down like an outlaw in the old west.
