That S&S kit is so extensive you might as well as buy a ready-built engine! It will be a lot more robust and involve much less expenditure of effort to build. I went through the exercise a few years ago of further enlarging my stroker. The cost of additional parts, plus labour to rebuild, was admittedly less than buying a new engine, but not by much!

 

I would have to agree, especially when factoring in the value of selling the old engine and one's time hassling around all the inevitable 'issues' likely to arise.

Or, better, keeping the old engine to put back in when you sell the bike.

What's the lowdown on 5" flywheels?

 

They were a shovel racing feature I suspect. Sounds like an early S&S and Warner Riley adventure at Bonneville!

 

Stud ripping good fun?

 

My favourite mag back in the '70s, while I had my shovel, was Big Bike, in which Warner Riley wrote occasional articles on his exploits. He eventually broke 200mph at Bonneville by a hair's breadth one year, having started with several newly built engines, but having broken them all and rebuilt a decent runner out of their mortal remains. They were all very long stroke Sporties (around 2 litres as I recall), running on more nitro than was wise, so stud stripping? Plus a lot more!

 

If this guy has an item for sale you are interested in he is a jam up seller to work with.

 

what is a "jam up seller"??

 

Great guy to deal with.

 

thanks

 

I may just go with head work and new pistons, it has the EV27 cam, would 10 to 1 be ok on the pistons or something less, like 9.5 or 9.75?
