    This would be the revised ZL1 with different bore/stroke ratio. Displacement was 430 cu. in. but it was still referred to officially as a 427. Several CanAm competitors in period ran all-aluminum big block Chevrolets with 430 cu. in. displacement--and some were much larger.

    March 16, 1969 is extremely early for any ZL1/L88 engines to be out in circulation, perhaps the date is incorrect. The Monaco Orange car was built in mid-December 1968 and Roger Judski's car was produced in June 1969. Zora had a few development cars and some motors were used for "field testing" with race teams. I believe that two engines went to Troy Promotions/Tony DeLorenzo for Sebring in March 1969.
    This precedes the COPO ZL1 program for Camaro as well. The Chevrolet Engineering Build Order No. 19638-69, To provide engines for certification and development was dated 3/22/69.

    The revised ZL1 had a shorter stroke.
    The initial Reynolds big block displacement was 491 cu.in; later various displacements up to 510 cu.in.

    Bill Jenkins experimented with various bore / stroke combinations for the aluminum 427 as it changed the torque range of the motor among other things. Initially this aluminum big block was the motor for NHRA Pro Stock against the Chrysler Hemi. However Jenkins later tube frame Chevrolet Vega with a small block changed everything. Jenkins quickly scooped up a quarter million dollars in race winnings after his Vega was declared legal by the NHRA...

    The Survey shows 710216 as a yellow Top M40 Corvette. Do you have something to confirm that number as being an orange Corvette?
    The number '215' may have simply been a dealer stock reference number. It seems unlikely a dealer would know the sequence number build for L88 Corvettes.
    In the Survey list 10 of the L88 M40 equipped Corvettes have been accounted for.
    Sorry for the delay in answering!

    Not Kevin then but the Corvette seems to be finished to a very high standard.
    The small details are amazing and especially both sides of the hood. Is that a pack of cigarettes on the console, matches in the ashtray?!!! :)
    This Corvette deserves it's own book to cover the history.

    Quite the history for that 1969 Corvette; especially with the motor ending up in a boat...
