Car Forum / Ford / Ford Mustang / June 2005Good explanation of modular engines vs. older V8's?
Hi all - I am curious, when FoMoCo made the switch from the old 5.0L V8 to the 4.6L modular engine, what is the difference? What does "modular" mean, anyway? Thanks, Thomas The mod motor first came out in the 1993 Lincoln Mark VIII. "Modular" refers to a design concept that was intended to make it easier to add or subtract cylinders, i.e., to turn the V8 into a V-10. Since Chrysler did the same thing with the Viper motor, adding two cylinders to its 40 year old small block, and Chevy did the same thing with the S10 motor, subtracting two cylinders from its *50* year old small block, I'd say it was not exactly an engineering breakthrough. 180 Out On Wed, 08 Jun 2005 09:08:32 -0700, one80out wrote: > The mod motor first came out in the 1993 Lincoln Mark VIII.

No, it was the 1991 Town Car. > "Modular" refers to a design concept that was intended to make it easier to add > or subtract cylinders, i.e., to turn the V8 into a V-10. Sort of... but it's more than that, much more. > Since Chrysler did the same thing with the Viper motor, adding two cylinders > to its 40 year old small block, and Chevy did the same thing with the > S10 motor, subtracting two cylinders from its *50* year old small block, Again... sort of. The Chevy was only 22-23 years old when it was configured into an odd-firing V-6(the 3.8 Chevy - not to be confused with the 3.8 Buick - which everybody did). It was before the S-10... the S-10/S-15(remember them?) original V-6 was the even-fire 60 degree 2.8 Liter. > I'd say it was not exactly an engineering breakthrough. Well, the Modular Ford is a very rigid, precisely built, and clean running engine(passes w/o thermactor / AIR Pump) with an excellent HP to CID output... and is an OHC design, sharing NOTHING with any engine it replaces. It is quiet from a harmonics position, free revving & breathes well. The accessories are rigidly mounted to the engine too. See: http://www.babcox.com/editorial/ar/eb40228.htm for a good overview.

After the 2.8 in the S-10/S-15's it was the 4.3 liter V-6 never a 3.8. >> I'd say it was not exactly an engineering breakthrough. > [quoted text clipped - 11 lines] > >Rob  Signature"Either kill me or take me as I am, because I'll be damned if I ever change..."

Right - the 3.8 was before the S-10. Never said the 3.8 came in a S-10. Rob > Again... sort of.

I know someone that built a V6 Chevy to race and it was the 4.3 V6. I don't remember too much about a 3.8 Chevy. Signature3am is _never_ a good hour for a summoning - a moment of lost concentration and you've got Nader instead of Nyarlathotep. Amphetamines are not a good idea either: unsafe at any speed. - Cadbury Moose >> Again... sort of.

It was the VIN "K" engine - 229 CID vs Buick's 231 CID. By 1985 it was 4.3 Liters / 262 CID. Most people remember the 5.7 L Olds diesel... same era, up to 1984, but how many remember the 4.3L / 260 V-8(1979-80 - Olds only) & 262 CID V-6(82-83) diesels? They were available in some GM cars - Malibu/Regal/Cutlass & other Olsmobiles... also an Olds-based(not "converted" gas) engine - and I think the 262's were the only "Olds" V-6's!

Mods are covered on pg.2, but this is a good read on ford engines...: http://www.fordracingparts.com/download/enginetips/enginetypes.pdf Rob |
