I just saw this on you tube, and I thought it would be interesting for you who have never seen a 4 port for an A. It is running, and you can here what a good sound it is! http://www.youtube.com/watch?v=b6xsOpzba0Y TraderJack
And, need you more, here are pictures of the engine. Always nice to see pictures of the engines , apart , no less http://www.teamvesco.com/444littlegiant/modelaraceengine.html Why am I so interested? John Vesco was my friend and in the SDRC with me! TraderJack
I recall that Vesco's 4-banger turned speeds in the 130s at the drags way back -- really impressive speeds compared with V8 fuelers of the day.
