I have heard the MPC boxing of a 1969 version Hurst Hemi Under Glass is merely a re-boxing of the AMT1965 Hurst Cuda rear engine " funny car". It was originally part of a series of AMT funny car models that were all not- to- accurate versions of early altered wheelbase drag cars. The best parts were the bodies and drag parts for the chassis and engines. A note on the Hurst Hemi Under Glass, I saw a photo of the original prototype car in a drag magazine, taken at some car show. The hemi engine had the twin 4 BBL carb set up that their superstock hemis were equipped with, the manifold with the carbs staggered side by side, not tandem. The big rear window had nylon- type straps to lift it off for engine access. The front suspension on AMT'S version is not accurate and I once saw a shot of the cad doing a wheel stand and it seemed to have a belly- pan underneath. Last, AMT's Corvair rear engine funnycar from the same series has the exact same engine, suspension chassis and interior as the ' Cuda kit, so much so that the included dashboard does not fit the corsair body without modification. Long winded but I hope this helps.
