Are you on Facebook? There is a page just for Antique Ford pulling that has a lot of good people and info on it. If not I can get you the numbers for some guys to talk to. I pull a 960 and my dad pulls a 671 but we are just running a 172 with head work in the 960 and a 172 with 4 inch overbore kit in the 671 with head work. I haven?t ventured into building big cubes yet.

Yes as ford 9000 said join us on facebook the antique ford pulling group. Eric posted a good recipe for a stroker build there. Later Ind blocks are a bit beefier. In the higher RPM/weight cases some are snapping the 172 cast crank. So they look for forges steel cranks out of diesels. Most prefer the 144 cause no balancer. They're hard to find or go with custom Bullit crank for some big $$$$. Most are using the 600 head cause the compression chamber is smaller increasing compression. Or find a 192 K block out of a worthington G10, chuck and duck woodchipper, genset, irrigation pump, or leaf Vac. Building a 960 now with a friend. Ind engine, diesel crank and Later HD flywheel.

Kirk, will you have it done for Harrisburg?
 
Anyone know what cylinder head was used on 70s vintage four cylinder 192 natural gas engines?

Obviously the compression ratio was increased for use on natural gas but it's hard to imagine that Ford cast a special head for the 192 NG engine. Of course, the use of a 172 gasoline cylinder head would result in a higher compression ratio than the same cylinder head used on a 172 engine with smaller bore.

Asking because I have one with VERY low hours. I've "converted it to gasoline" simply by removing the NG equipment and bolting on a late 172 "big" carburetor.

I'm guessing that the NG engines needed significantly more compression than did the gasoline versions. 8.5:1??? Seems like I've seen the CR spec somewhere but cannot recall where.

I don't know if they used the same head the NG as the gas on the 192. If you have some numbers I can run it against what I have on 92 gasser. As far as the 172 head on the 192 engine it's not a bolt and go. There are more bolts and bolt holes are in a different location. Some guys have drilled and tapped new holes to accommodate the 172 head.
 
Them is some good looking pullers. I've pulled with my 950 but I'm running and doing well with my Ratty stripped down NAA in the 2500 lb class

Are you guys pretty competitive? How heavy of weight classes before you power out? Just wonderig
