94's and Stromber 97's use the same 3 bolt bolt pattern, so you can use either on that mainfold. 4TTRUK
94's will contact each other, so you have to clearance them a little with a grinder. It helps to use a thick carb gasket that's fairly soft, as the carbs need to tip away from each other a little. Been running that combo for years.
Yep, I know that, but 94s take up more space than 97s. Thanks BigMikec, I had a feeling that was the case.
