    The front wheel almost looks like it has a locking hub on it. Prototype 4WD Camaro?

    So, I was reading about some dudes chevy 350 swap..I was just curious why would you need to use a different radiator? i mean, I realize that the input/output deal is opposite, but couldn't just longer hoses resolve this?

    I think you already have most of the ingredients for a good performing 304 recipe that I have built before for a good friend. This engine was a strong runner and performed really well. We are Hotrodders as well and have been playing around with musclecars for years so this is not coming from someone who hasn't been in a hot performing car. The jeep was an 82' CJ 5 with 4.56:1 gears T18 and dana 20. It ran 35" tires with stock axles. We used a good running fairly low mile stock bottom end, that we didn't even mess with. We pulled the heads and did some real easy port clean up and gasket matching, then sent the heads in for a 3 angle valve job, and new guides. The valves were left stock with only one of them needing replacement. We added new springs and keepers that were recommended with the edelbrock performer cam. #2132

    ENGINE: AMC 290-401 V8
    RPM RANGE: 1500-5500

    CAUTION: Use only Sure Seat Valve Springs, #5832 or 5932 Use stock ratio rocker arms only

    Duration at 0.006" Lift: Intake: 278° Exhaust: 288°
    Duration at 0.050" Lift: Intake: 204° Exhaust: 214°
    Lift at Cam: Intake: 0.280" Exhaust: 0.295"
    Lift at Valve: Intake: 0.448" Exhaust: 0.472"
    Timing at 0.050" lift: Open Close
    Intake: 3° ATDC 27° ABDC
    Exhaust: 42° BBDC 8° BTDC
    Centerlines: Lobe Separation - 110° Intake Centerline - 105°

    CAUTION: Use Performer-Link Timing Set, #7818. Do not use late model timing sets. They are machined in a retarded position and are not recommended for this camshaft installation. Edelbrock Performer-Link True Rolling Timing Sets feature three keyways for specific timing selection. Always use the “0” or straight-up timing mark when installing Performer-Plus camshafts with Performer-Link Timing Sets.

    You could also try the Comp XE262 - Adv Duration: 262/270, Duration @ .050: 218/224, Lift: .493/.500, LSA: 110 Cam. That is the only thing I would maybe do different today, other than going to oversize valves and a DUI HEI type distributor or MSD distributor and MSD6 box. We put this engine together with the Edelbrock cam, new timing chain, Edelbrock intake, transdapt adapter and quadrajet carb, along with headman fenderwell headers. I can tell you that this thing ran great. It had plenty of performance on road and off. It also didn't do all that bad on gas. This same Jeep later ran a stock 401 with the same intake and headers and in comparison the 304 was still no slouch. He probably would not have replaced it if it wasn't for destroying the engine in a deep watery mud hole. I can't say what kind of horsepower that thing produced, but it wouldn't be far off of your 1hp/Cu. Maybe approaching 200 hp at the rear wheels. And in comparison to a Ford 302, the much vaunted 5.0L only made 215 SAE net HP. They are even less at the wheels. Stock 5.0L Ford engines make good performing jeep engines too. Don't get too caught up in the numbers. Torque is where it is at and that 304 can still make enough torque to haul that Jeep around fine. They still will make more torque than a 258 and have a greater rpm range to use as well. It is nice to be able to buz the engine up into 5500 or so, for some mudding, or a rip up to speed on the on-ramp. I say re-ring and bearing that thing and put those goodies on and drive it. You should be happy. Then you can always keep an eye out for a 360 and hoard it away for a future build. Your intake and headers will work great with it too.
