oh no, ford carbs on slant!
and so it begins, what combo will we see next, a ford 300 head on a 225 block with a chevy 250 crank? let the Frankinstien engine expermants begine!
"Frankenstein" experiments are not likely in this case, because the 250 Chevy engine has 7 (seven) main bearings; the slant 6 has just 4... plus the 250 Chevy crank has a stroke about a tenth of an inch shorter than a 198 slant; It would give you about 192 cubic inches, so what would be the point?
The Ford head would never work because of the mismatch between the bore size (Ford is 4"; /6 is 3.4") and the combustion chambers....
If you want to go stupid fast with a slant 6, you need to think about either N20 or forced induction. Forget about trying to make it "BIG" with a lot of cubic inches, because the head will always defeat you; it was designed for 170 cubic inches, and while you can port it and put (somewhat) bigger valves in it, the small bore dictates valve sizes that won't allow the kind of really impressive flow numbers necessary for high specific output (1.75 HP/cubic inch, for example.) The 170 CAN get those big specific output numbers by spinning 7,500 RPM but unless you're "class racing" where engine size is a factor, the displacement deficit is just too big...
Mark Etherdge (Guzzi Mark) has proved that you can go as fast as low 11's normally-aspirated with a 225, as long as you're not pulling a lot of weight (I think his car has been lightened to about 2,350 pounds,) but most A bodies are up around 3,000 pounds, and beyond, which changes the picture dramatically.
I think the slant 6 is one of the greatest engines ever to come from Mopar, and I am really excited about running one in our car, but they take a little "understanding." I wouldn't run anything else...
Well, now that I have learned a little about them, I wouldn't.
Before I knew much about slant 6's I built a '72 Valiant with a 360 Magnum with a blower (Vortech,) but if I had it to do all over again, I'd put a slant 6 in that car... seriously. In a New York minute!!!
They are just amazing...
