Very nice work work Ken! The valves seem just right for that chamber looks like you've done what can be done for that little head. What are those nice slugs? My 228 has big pop ups (stock)? so how much did you chop the head and block to get decent compression?
I'm looking at 1.94's from chevys.
This is a OLD car build probably after WW2 from a 1/2 ton 39 GMC P/u Eric, I'm redoing it as it was originally using only the old bits so no aeroquip--tho it was available surplus come to think of it. In those times there weren't very many standards but each track often had their own specs.
This car seems to have followed the 'junk class' rules: 270cu.in. a certain cockpit size, wheelbase, etc. It has a 34 Ford P/u grille surround and a pointy tail.
I don't plan to run it in the circle tracks but may be able to run at the Buttonwillow raceway course not too far away.
To me it's just doing a piece of what I like to: a recreation of a modified sports or racing car.
I do all my own work with exception of the heavy machining--have none of that serious machinery. This fits with the way cars were built then, most weren't works of art.
I'd really love running downdraft piping through the top of the head like Holbay did on the English Ford for Formula juniors. To that extent, I'd like to saw a damaged head up to see where the iron is.
Ive been building racing engines for a long time so this is the only problem I see with the GMC engine.
I'll keep the list posted as I go along.
cheers;
