Drew, is there enough meat left in the cylinder, opposite of the pushrod galley, to hold a gasket, and keep it from blowing out? looks mighty thin there, but the bore is HUGE! woo

Going to scale down a cast grill, make a mold, and it'll be aluminum.

It'll all be welded in when they figure out how big/where they want the valves. It'll all be flat. No pocket like there is in the pic.

Nice. I have 3 kohler command motors in the barn. One of these days it will be in a pulling tractor. So far how big of a valve were they able to install in the engine? So $4900? Not bad for a 80 HP engine. I'm guessing for a pulling application they will just change the cam.

Haven't decided on valve size. Cam and flywheel will be different. The small block singles can't make 80.

Well no. I know the small block singles can't make no 80hp. I was thinking about doing one for my local club in the 12 stock altered class with a full roller motor.

Nqs possibly will be adding these to the 30 cube class in the future. The flatheads will get nitro and the ohv 30 cubes will run alky.

That's what I'm waiting on to hear from NQS about these engines before I build mine.

looks awsome, but why a custom tillotson, when you could use a Keihin FCR 41mm or bore it to 43.5mm they are very cheap from ebay and much better alternative, usualy found on motocross and ATV in the 450cc range before they went to fuel injection, Or a Mikuni HSR 45-48mm they are made for a HD but harder to work with

Julian had called tillotson and had a conversation and that's just what he decided to go with.
