4.0L HO Jeep Engine Build
I built a 400M and added Austrailian closed chamber 351 Cleveland heads, forged pistons, a Crane Fireball cam (am I dating myself? lol), an Accel dual point, a VS 750 Holley, a Holley Street Dominator intake and Hooker headers and this Torino would do 140 easy and cruise 120 all day long. I made it from Carbondale to Chicago in 4.5 hours when my girlfriend was going to SIU. :-D I never tried advancing the stock cam on one though. These engines had a tremendous amount of unrealized potential and John Kaase just won the Engine Masters competition with one. I even raced a Grand National with this Torino and blew right by when the computer killed the fuel at 130-135. BTW, this was on a very straight four lane hwy very late at night. :-D BMW drivers jaws dropped when they found out that I had another gear at 110. Obviously, it had a 2.73 rear gear. :)
Anyway, enough "Glory Days" reminiscing, lol. I could pull the timing back by sloting the CPS attachment screws to the bellhousing and I may be able to phase the distributor correctly with modifications, but it would be very tough to figure out how far the timing was really reduced and it's almost impossible to get at with everything assembled. I really have to put some thought into this mod and try to justify to myself that it's really worth it. If the CPS truly controls then ignition, the cam advance should not effect timing, so that just leaves rotor phasing as an issue. I also am a little leery of the bushing installation in the cam gear as I've never done that before. I assume it's a press fit? I hate to have that bushing fall out.....
Here's the detailed factory cam specs. I may run a dyno sim and see if it's worth it.
