What is so different between the L and LA that gives the LA more power. I have a 1936 L and compete against a few L's and LA's in local pulls. Us L guys are pretty close to each other but we simply can't get close to the LA's. We all have FIRESTONE F&R tires which are even the same size. The L powers out. The LA spins out. Any ideas out there!

Actually the biggest difference is the pistons. The Standard L pistons are at TDC about 1/4 inch below the deck, the standard LAs are at deck height. I don"t remember if it is the pistons or rods, almost 100% sure it is the pistons. Both used dual fuel head 4447, if you can get higher compression pistons from LA and a LA propane head, you can go after your friends. Next problem will be weight. If you have cutoffs, they will have a lot more traction with the heavy cast hubs. Good luck.

The only major diffrence in the LA engine is cylinder heads. You have higher compression heads available on LAs. They will fit right on to a L. Then there were over bore kits that would fit in both. Hope this helps.
