I'm not reading it that way at all. Without the wing they could of still run the hemi. It was moot anyhow since all big blocks were "banned" shortly there after.

 

The following is taken from a Hemi historical website.

Does this all sound familiar?

Remember 1965 when Dodge sat out the season because the Hemi was banned?

Or how about the short life of the Daytona/Superbird? Banished to being only able to race with a small block engine. Or the restrictor plate changes made to hold the Hemi back. And the final insult, the change from a big block engine to a small block, only so that GM cars could finally compete.

Much to the credit of Ford, they found the Chrysler Hemi engine a challenge to over come, and gave it the best compliment it could, when it introduced its 427 "Semi-Hemi" engine. Then, it upped the ante by making the dual overhead cam 427 "Semi-Hemi", which resulted in Chrysler designing and submitting to NASCAR, a 426 dual overhead cam Hemi. To this NASCAR responded with a "Don't even think about It." statement, and promptly pulled the 427 Ford dual overhead cam engine off of its approved list. Ford and Chrysler both helped to build cars that were more aerodynamic, and helped push the development of parts that were to benefit the average car owner in the long run. But the gas crisis, mountings fiscal pressures, and finally disgust with NASCAR, prompted Chrysler to pull out of NASCAR racing after the 1977 season.

Considering how that statement butchers the fact the Ford engine was a SOHC and not a DOHC the rest of it is pretty much how I've said it.

The hemi couldn't compete in '65 because it was not a production engine yet.

From '66-'71(?) The "older" body style Chryslers could still use the Hemi, it was only restricted in the winged cars.


The small block mandate was across the board after '72(?)


(I apologize if my dates are a year or two off, it's mostly from memory)

 

ok well if the 427 was so good (im not saying its not, by the way), why do top fuel funny cars and dragsters use the hemi engine?

Simple, because the mopar was out a few years before the SOHC 427 and then Ford dropped the SOHC 427 for the BOSS 429 it was easier for major builders; Ed Pink, Alan Root, Anderson, Keith Black to "BASE" their race motors on the more plentiful Chrysler. Also consider what's easier to tear down and overhaul between rounds, a SOHC motor with a 7' timing chain or a push rod motor?

The Boss 429 still is produced by a few foundries and is used in blown alky boat and car classes. To my knowledge there is no solid blocks made for top fuel of a Ford based motor.

BTW a current Top Fuel motor has ZERO chrysler parts. Try finding an aluminum block hemi with no water jackets in any Chrysler parts book, past or present. Or dual plug heads run by twin magnetos for that matter.

I'll agree the current top fuel motors have their roots in the venerable mopar. It was a great race motor.

 

i know they dont'use chrystler hemi's but are designed after the hemi engine, like you said. i said heim in a loose term, because its a hemi engine.

i just have to ask, since race'ers have a big budget and can have bacicly anything they want (like john force's forged blocks) why cant they have a 427? that was a verry good point about teardown's between races, expecially since they just shortened the time not so long agao. but do you think that is the only reason?

i'd love to see some differant engines in the feild, it would make entertaining.

 

June issue of Sport Truck: "the six speed transmission propels the Ram to five-second 0-60-mph times and the standing quarter in 12.9 seconds. To peak your interest just a little more, PVO managed a suspension tune that lands the SRT Ram with a 70-mph slalom speed that'll pull 0.92G's in the corners."

Car and Driver mag reports the 03 Cobra in the 1/4 running 12.9@111mph.

Also the Corvette ZO6 running 12.7's in the 1/4.

Deja Vu 1960's or what except now trucks are involved.
I think they're all awesome times for stock tires.

Question- since Ford is coming out with the 03 F150's with the 3 valve SOHC 5.4, does that mean the Lightning also gets a 3V boosted or just the regular 2V engine like 2002?
