More Numbers....
So, I scored that 410 conglomerate engine. It is the ribbed block, I assume truck block. The heads are numbered: C7AE-A.
I also scored a 4bbl intake that is numbered: 5E5: C5AE9425C.
My question is, what years and applications are these from and would this intake work well for a torque monster towing engine?
I have heard that all the standard heads are the same, but my dad claims his 390 stroker has some spiffy better heads on it with bigger valves than most had.
My 390 currently in the pickup has one C8AE-H head and a C7AE-A head, is this an issue? It seems to run fine.
Also, isn't there a book called "The FE Bible"? I have not been able to find it.

The heads are numbered: C7AE-A. 1967 car motor small ports.
........4bbl intake that is numbered: 5E5: C5AE9425C. 1965 car with large ports. Not a match to your heads.
......one C8AE-H head and a C7AE-A head, is this an issue? No, they are the same.

Thank you
Thank you for the info. What numbers should I look for on heads to match the intake? Or should I just get a different intake? What will be best for torque in low to mid range?

The chamber size and volume is different from the C7-A to the C8-H head. C7 has the round D wedge shaped chambers aprox 74-76cc's. C8 the newer rounded shape chambers a tic smaller at aprox 72cc's. So yes having one of each can be a problem.

So, I want something of a C5 nature to match the intake? I have 2 more parts engines to glean from, both are from '68 F100s. Probably not what I am looking for, but I could get lucky I spose. I will have to check tonight when I get home.

Well good luck with that. 2 different chamber shapes one with a prechamber design around the plug and the other without?? Will it run?? Of course but how well is the question.

I'd like to see pictures if you can post them.
332-428 Ford FE Engine Forum: I think the C7AE-A had at least two flavors......
Interesting comments from Bill Ballinger:
332-428 Ford FE Engine Forum: Another thing about the jellybean chamber heads......
So I guess there is more going on here than a minor pressure imbalance between cylinders.
I'm confused by the intake recommendation Bear. I thought the later "S" and "T" intakes were better for low to mid RPM torque.

It would be interesting to see if there really are 2 types of C7-A heads. Some confuse the C7JE-A 427 lowriser marine heads with the C7AE-A's. My C7AE-A's were non thermactor heads on my old bone stock 67 Shelby's 428PI. With 2 versions on the C6-R's it wouldn't surprise me at all tho. And like the R heads compared to the CJ's for example could be as simple as the intake runner angle being different. Although they are very similar otherwise. While I never witnessed this in person I've heard of virgin stock FE's coming from the factory with 2 different heads. And just when you think you've seen it all new things pop up and blow me away. Like those SS C8WE-A cheater CJ heads with the small C0AE-D style chambers that were for sale back in May. For years I thought those were another myth...but there they were. Damm!!! LOL.

wow
The ol' 390 also has 2 different style valve covers on it. that is why 2 different heads didn't surprise me.
Back to the intake for the 410. Would I be better off to run an edelbrock intake? Could a guy port match the big port intake to the small port heads? I really want it to be a low end mid range engine for towing and work horse type activities. We would all like to be like Scouder, but that would not fit my reality. Are those heads the ones I want for this type of application? Just a different intake? Would I be better off staying with the 2bbl carb?
