When I first built the 1296 engine for Tiny Tim, I decided to use a large valve 1500 head. In doing some measurements I discovered that the combustion chambers of the 1500 head were much deeper than the 1300 ones and if I did nothing to it, the compression would be extremely low. Shaving the head on the order of a quarter inch achieved the compression ration that I was seeking. I sourced pushrods from Ted Schumacher to achieve the correct rocker geometry. I also had Ted get me a set of Isky dual valve springs and roller rockers to complete the upgrade.

I did have some issues with the length of the head bolts though. > Date: Sun, 3 Jun 2012 10:45:11 -0600 > From: [email protected] > To: [email protected] > Subject: Re: [Spits] 1300 vs 1500 manifold > > Dave wrote: > > will an su intake manifold and carbs bolt up to a 75 1500 engine? anyone done > > that? > > > > Yes.
