The Triumph engine is a really good starter for a hot rod Brad. I've got a T100 500 the same as Verns that's going into a BSA C15 250 frame for pre 60. Those little Trumpy engines hoot and they're so small they fit in just about everything from a Rickman Zundapp to a Maico. A good conversion is to fit one to a Sprite/American Eagle/Alron frame which would be legal for pre 65, 70 and 75. The 650 engine like in Doug's AW is a fair bit bigger and I doubt it'd fit either the Maico or CZ without lengthening the cradle. I'm going to fit my 650 into a lightened stock frame for pre 65 and later as a street tracker. I'd be using the 650 for pre 65 if I was you, they're arguably the best engine (bar Matchless) and you can fit them to all sorts of frames. For pre 75 it's a lot more difficult because of the size of the bugger. The little 500 motor is almost as quick but much smaller and adaptable.........just my 2 bobs worth.
Below...just to prove that a 500 Triumph in a 70's Rickman Zundapp isn't all bullshit, here's one in street trim. Imagine it with serious pre 75 suspension and you'd have a great little pre 75 four stroke class racer
