    '71 C-10 pickup.

    1975 std bore, std crank, stock rod, stock bolts, stock valved stock rocker 500 [slight back cut on intakes]. Non-stock parts inside are a Howards cam and yellow GM behives from LS engines. Slight compression increase via .013" block cut and .024" head cut. 493 heads with bowl work and pushrod turn work, exh short turn cut down a bit. 8.6-1 CR.

    One .090" x .090" Somander groove in each cylinder's quench area, aimed at plug. 2215 edel, 1" open spacer, large primary QJ from a '76 caddy. Points, cheap yellow Accel wires. 87 octane, 36* timing. Cam is slow ramp 232/240 at 50, on a 112, .536" lift with stock rockers, installed +6.

    1.875" x 3.5" headers, 3" exhaust with bullet race mufflers [2 per side]. Switch-pitch 400, 3.55 gears, 29x18.5 mickey pros.

    Weighs *apx* 3860 w/o driver. 13.39 at 98 in fair air at 1250' track elevation in street trim. 1.82 sixty foot.

    Dave

    update:

    Swapped the too loose in low stall PAE convertor for a stock 2000/3000. Sixty foot went to 1.79 but rest of run was slower due to a different governor shifting at a too low 4100 rpm.

    Swapped in 4.10 gears, X pipe exhaust and raised intake roofs in the heads. Went 13.32 at 98 with a better 1.73 sixty foot in very poor air with governor set for apx 4700 shift.

    Another track with a so-so starting line, but better air gave me a 13.10 in same configuration. Removing air cleaner and dropping tailgate gave me a 12.97 at 100 with a 1.74 short time on both runs.

    All runs on 87 octane.

    You can call me 74 Novallac now. I used to be Bonneville 500. That car is long gone but the engine is going into my 74 Nova. It used to be a ten second drag car (with a 468 chevy) that the guy I bought it from had returned to the street. My wife and I have made quite a few street improvements to it, i.e. power fourwheel disc brakes, power steering, better seats, heater, more streetable 2.75 gears, etc. I can't wait to see what the Bonneville's old engine will do in this car considering the heads have been fully ported and it now has headers and a Cad Co. 250 cam and shaft rockers. I plan to get an Edelbrock intake too. Been thinking about a 125 hp N2O kit but up here in N.H. that's illegal on the street. :nono: :weeping: The Nova has been backhalved with a nine inch ford rearend, full rollcage, ladderbars and coilovers. I found the former race days owner and he filled me in on what the car was like then. It pulled wheelies and ran 1.5 sec 60 foot times. Should be fun as a street car! :yes: The engine coming out of the Nova is a crate 350 with a Weiand 177 blower. It runs great and is for sale for $4,000.00 :eyebrow: I wonder how the gas mileage will compair? Best I ever got with the chevy combo was 17.5. :thumbdown:

    This is the day my wife and I bought it. Like I said, we've made quite a few changes since then.

    I met fuzzy today and took an old 472 block and heads off his hands. Sad to say that the old Ford truck is no longer part of his livery. Super nice guy to talk too and had a neat VW/sbc project in the works. I hate to lose another Caddy fraternity member though.

    That looks to be an awesome ride Terry, I'm hoping to get into the 10's with mine when finished, my engine spec is very very similair to yours so you have given me hope !!!
    My spec is
    500 block bored +60" decked, oilways ported etc etc
    10-1 KB flat tops & Moly rings
    MTS 120cc ported/polished heads
    MTS 20 cam
    MTS rocker shaft kit
    Edelbrock inlet ported and matched
    Holley 850cfm Carb, slightly modified
    TCI trans with transbrake


    I couldn't help noticing your running stock rods, Have you encountered any problems ??? I was under the impression they wouldn't hold up to big power.
