What's New for 1968

[CycloneFE]

Moose,
The base I believe was the 302. No 6 cyls. I will try to get some info and post. That brochure did not list the engines. I think it was a VERY early brochure. I think the 302, 390(3 versions) and later the 428. I think the 351 was in 1969. I will try to find a hardtop pics too.

Moose,
Stole this from wickypedia,
The 1968 model was named the fastest car of that year, because a '68 Cyclone ran a world record speed of 189.22 mph (304.5 kph) at Daytona. New engines were introduced for '68 as well. There were two versions of the 302-cid engine: the two-barrel carburetor code F, with 210-hp (156-kW); and the four-barrel carburetor code J with 230-hp (171-kW). There was also the 390-cid (6390-cc) engine with either: 265-hp (197-kW) two-barrel carburetor; or 335-hp (249-kW) four-barrel carburetor versions. Then, getting into the big guns: the 390-hp (290-kW) version of the 427-cid (6989-cc) side oiler engine. This engine was only available for a small part of the '68 model year, and was replaced by the cheaper 428-cid (6997-cc) with "only" 335-hp (249-kW).
NHRA's guide bears out what wicky says, but it lists 4 different 428's
