You are incorrect. The 390 GT engine was still available in the 1969 MachI( possibly others),I owned one.They were available early on and then dropped..they draw pretty high$$ now. It was GT in name only as it was extremely de-tuned, more like a T-bird engine. It no longer used the Holley 600 on a hi-rise of the earlier ones and the cam was a T-bird grind, the carb was an Autolite/Motorcraft 4 bbl on a lowrise intake.
I missed that it was a 410 build, the comments on the 410/428 pin height are correct.They use the same crank and rod length.
