cmbeau67 Posted September 3, 2018 Report Share Posted September 3, 2018 I have a 521 with a mercury capri v6 in it. I'm told this was a common swap back in the day. I still have the conversion directions. Makes for an interesting time when the counter boys ask "which engine"? 1 Quote Link to comment
datzenmike Posted September 3, 2018 Report Share Posted September 3, 2018 Never heard of this but have always maintained that a V6 is a sensible motor swap for 520/620. 1 Quote Link to comment
mainer311 Posted September 3, 2018 Report Share Posted September 3, 2018 It would seem logical that any aluminum block V6 would be a great swap if it fits, since it’s likely comparable in weight to a cast iron block 4 cylinder. There are a few Datsun roadsters with VQ35 swaps in them and they’re stupid fast. 1 Quote Link to comment

mrbigtanker Posted September 4, 2018 Report Share Posted September 4, 2018 The Buick V-6 was the most common. 1 Quote Link to comment
Charlie69 Posted September 4, 2018 Report Share Posted September 4, 2018 A friend of mine back in the late 70s had a Capri V6 in a 78 620 with the auto trans and it was a quick little truck 1 Quote Link to comment
