  • R-1 differences

    I know it has been discussed before but can someone please tell me the major differences between the standard 289 and the R-1, beside the chrome stuff?

    TIA

    higher compression (different pistons,) cam, aluminum cam gear, higher volume fuel pump, modern style vibration damper, revised oil pan (windage tray and breather in side of pan) R-1 specific AFB, dual point distributor

    those are the big ones off the top of my head

        YEARS ago I had a '61 Hawk with a four-speed and the (I believe) 225 hp 289. The R-1 seems to have a lot of "upgrades" for only a 15 hp gain. (For instance the AFB seems to me to be a BIG step above a WCFB). I've only driven an R-1 once and one R-2 with a sick supercharger and both of these engines sure reminded me of that '61 Hawk--I don't recommended shutting the eyes while driving, but if I had I believe that either of those would have felt just like that '61 Hawk years ago. To me the R-2 seems like a big step up in hp from the R-1--even without getting deep into the supercharger (i. e., high revs). Perhaps the whole answer to this is that I never had the '61 Hawk tuned right as it always seemed to be a dog (don't want to offend anyone here who has a 225 hp 289--just giving my personal experience). Anyway, just kicking two cents into the kitty.

            Greetings, wagone,

            Most of the R1s 15+ hp come at the top end of the RPM scale. Your comparison is accurate, as most 225hp V8s pull as strong as an R1 from idle to mid-range, but run out of cam and valve spring around 4500-5000 RPMs. The R1, in good fettle, will pull pretty strongly up to 5500 RPMs.

            FWIW, the AFB carburetor makes the least difference versus the WCFB. It is the 10.25 compression and the extra camshaft duration which makes the horsepower and the revs. FWIW, unless it is a show restoration, stay away from the Prestolite dual-point ignition. They were junk when new and a huge pain to set the dwell. Go for an old single-point Delco converted with a Pertronix kit from Fairborn or Thibault.

            Bottom line, nothing magic about any of the R-series engines. They were just over-the-counter 1960s hot rodding efforts added to what was a solid 225hp foundation.

            thnx, jv.

                The R1 is under rated at 240 HP. A well tuned R1 will perform extremely well on 93 octane gas. One problem with them is a lot of people reduce the compression and this will kill the HP.

                        OK, I'll bite, Mike; what is the "special part"?

                            R1 engines on up to R2, R3 and R4's need a special part that is NLA.
