I have a copy of the original SAE offering if it would be of help to anyone. It's carefully put away so I would need to dig it out.

KS

I've got that one, copied it in the basement of the UM Library long ago before they scrapped all that stuff.
But it says Torq=515 Power=616 for the SOHC-8v, which maybe a misprint although it does agree with the graphs in the paper.
Suspicious that those numbers later became the exact ratings for the 4v not the 8v.

SAE-650497 doesnt give 4v specs in the table but from the graph the 4v shows Torq=490 Power=580.
But it doesnt say if those numbers are SAE gross STP or Ford A-Curve or B-Curve or what.

Any dimensions on the header lengths?
Or cam lift?

Good to see the old heads get the job done, then again all those SuperStock wins came from somewhere.

Oregon Cams can do the 428CJ grind.
OR, I have run the Crower 270HDP & it idles & runs like a 428CJ.
Specs are very close at 210-220-112 vs the 428Cj specs of 207-221-116 LSA.

Unless you have a very trusted regrinder, and you also have to trust their surfacing & heat treating & lifter compatibility, etc.

Any info on exhaust (headers?) & dyno exhaust system? Or which dyno even?
That stuff can make a difference!

Ok Found it!
(For the exhaust open vs closed comparison)
Can you add:
What cam?
Which headers? (1-3/4 or 2-1/8 race supercomps)
Compression?

Also, when you ran the open header setup, were you carrying the exhaust system weight too? Probably 40 lb lighter without it at least.
Looks like at least 0.2 sec and 2+ mph gain running 'open"

So thinking about new exhaust for my car. I have 3 inch flowmasters right now and I have run them at the track and taken them off and they dont really hold the car back much. That being said the drone is just to much. I would rather sacrifice alittle bit and be able to hear myself think. What is everybody running. I really need to hear the different sounds whether they are Borla, Magnaflow or whatever else is out there. I dont want to make up an exhaust and not like the sound.

Curious what your timeslips looked like thru the 3" Flowmasters vs open (and where they were opened ie how much pipe was still on there)

I got a kick out of the last reader comment, "Do I see some sort of adapter to allow use of a 351C manifold?"  FE Power, still flying under the radar...

Did anyone see the other comment? 

"The poorest engineered of all of the 60's engines to come out of Detroit. A wedge style combustion chamber with symetrical intake ports. The worst lubrication system and an extremely heavy engine block for its diminutive 352 cubic inches. Only an emotional "Ford lover" would build this joke of an engine."

That was from a big dork named Dennis Moore, who apparently is a professional armchair engine builder.  Either that, or a Chevy guy.

There's some iffy engineering in the FE (exhaust valves too near the edge, washboard & ledge in the exhaust port, backwards valve cover bolts) but that is pretty minor stuff and NOT what Dennis Moore mentioned.

Ford's big 352 mistakes had nothing to do with the engine, which by the way was from the 1950s, not 1960s as DM seems to think.

1958 brought out the
Ford 352
Chevy 348
Mopar 350 & 361
All similar "big blocks" of the day, all low-priced affordable car market.
Heavy? The 352 was about 40 lb heavier near as I can figure, but also had a taller deck.

Ford's mistakes (other than the trivia I just mentioned) were corporate mistakes, not engine mistakes:
1. 352/300hp was WAY overrated as we all know. Shoulda been rated about 260-270hp. I guess Ford wanted the 352/300 to "make" 300hp to replace the 312/300 F-code of 1957 which was not going to happen with the corners that were cut along the way.
Chevys base 348-4v was only rated at 250hp, just about right on. The 352/300 was stronger but not 50hp stronger.

2. Chevy and Mopar offered their new "Base Big Blocks" but also lots of options, right from 1958:
348/250-4v base
348/280-6v
348/300-4v solid
348/315-6v solid
These all Gonkulate darn near their ratings, which may be why there are a lot of NHRA 348 wins and very few for the 352/300.

Mopar had options too:
350/275-4v
350/295-4v
350/305-8v aka Christine
361/305-4v
361/320-8v
The Gonkulator feels that these were a bit overrated (maybe 5% on average) but at least there were numerous OPTIONS, even in 1958.

Sadly, FoMoCo repeated this same blunder in 1966, with the 390GT:
1. Overrated at 335hp. Good engine, just rated too high - a trap that began in 1958.
2. No options other than the unobtainable 427. FoMoCo parts bin was overflowing by 1966 so no excuse this time.

I think DM was just jealous and making stuff up. But hey, without the good old Ford-vs-Chevy-vs-Mopar rivalries, this era of history wouldnt be complete!
