Look under the hood of just about any Mopar NSS car and you will find the 750's or the 800's. I'm talking cars that can run an index anywhere from a 12.50 et in 1/4 mile to an 8.75 et in the 1/4 mile
They work fine on my car and I run 9.60's and the most I have done with them is maybe change the jet size and the rods to be used. I also know of a few that have changed to a Holley from the 750 and actually went back to the eddy's. I also run one on my 70 Challenger 440 street car with no issues.
