Hi all,

Have Dolly Sprint 16v heads ever been fitted to a stag engine?

Hi Mark,

There is anecdotal evidence that Triumph were looking at 16-valve heads for the Stag and that a couple of engines were actually built, but that is as far as it got and the engines have never been seen in public. Pity as a 32-valve V8 would be something to experience, if it would stay together long enough!

Dolly Sprint heads wont fit as there is no RH equivalent.

There was a gentleman I spoke to at length at the last national day, I can't remember his name but he was serious about doing the modification to sprint heads. He even had a CAD 3D model of how it was all going to work.

Maybe he is a forum member....

Now this is interesting. The engineering problem is less that of turning one head around and produce some cam sprocket cover. The problem is to reverse the sense of rotation of the RH camshaft. The Dolly Sprint head will not work with the cam rotating anti-clockwise. The second task will be to manufacture two camshafts. Now if anyone volunteers to make a flat crank, one could use the original camshafts... Looks like tweaking the 16 valve V8 is a tad easier.
