Whoa, what's w/ the bashing of the Modular engine family? How is it a nightmare to maintain/fix? The only thing different w/ the Modular vs. Pushrod is the Mod engines have no pushrods, two longer chains, and chain tensioners/guides. I fail to grasp how this set-up is not only less efficient, but more complex? Unlike any pushrod engine, the Mod engines can live at high rpms all day long, can have cam swaps done by just removing the timing and valve covers only, doesn't loose any valve lift and duration due to pushrod flexing, and unlike pushrod set-ups, they have chain tensioners to keep timing more exact. Plus, unlike pushrod engines, multivalve heads can be done cost effectively, and since there are no pushrods, nothing pokes through the intake ports, and best of all, the heads put the spark plugs either on the intake or hemi style for easy changing. I'd take that over GM placing them by the exhaust any day. As for the Mods not having the tricks the import guys have, well, blame yourself. The high performance engines suffer the same problem the old street Boss 429 suffered: wrong people buying the car. So, compromises like hydraulic lash adjusters, tame cams, good mileage, etc. is something Ford does while the import guys don't. Hondas use solid adjusters, Subarus aren't the tamest to drive, etc. Remember, the Cobra R w/ the 5.4 did a job on the Z06 for that year. Replace the IRS w/ a solid axle for less weight, add some slightly more aggressive cams, current versions of those heads and bam, that car can still dominate the current LS3 vette, even if you add the interior back in it. However, the engine family isn't expandable but neither are the old SBFs when compared to the SBC. However, Ford's approach is better since it makes the engines more compact. It seems like you guys are afraid of new technology so anything new to you guys is just junk.
