Can You "HOTRODDEM:?

I used to build and race drag bikes my favorite was a Kawasaki KZ1000 with a heavily ported head and a 1327 big block kit. I did all of my own work and I happen to have a pro bench for porting and polishing and  also have older superflow flow bench, before they consolidated etc..... Do the engines (gas D-17, D-15) respond well the a nice bowl blend and a complete polish on the exhaust side? I wouldn't go crazy, just a little port matching and such, and maybe take 40 thousandths off the head. Would this be fruitful?

Maybe some of the guys on here who do pulling can help you on this one...

Those little D15 tractors are pretty peppy to start with.

I ran with Scotty Lee, at Lee's cycle salvage, and I ran by myself a bit at Cherokee raceway in Rogersville. Where you located pankey?

Wow roller rockers on a tractor motor, man that looks good, are they chevy or amc style? Good lookin setup. and you aren't too far from me, next time I go to the horse sale down there I will try to look you up.

Mark in Rutledge (almost your neighbor) is a big AC guy. You should talk with him. He posts here quite often.

Alot of ac fans around rutledge. You mentioned you like adding cccs to the kaw.you can add 200 cubic inches to the 226

Yeah I had a 1327 big block kit, and the head flowed monster numbers, I can't really remember but I believe it was in the upper 200's. It ran high 5's in the eighth. That's cool, do they make a dome piston kit for them with valve reliefs? I would probably wait till something tore up, but it's cool to think about. :)

Right you are my man, and once you have had a taste of the fruit from your labors your addicted, oh and by the way nice SSR. Hang on to that, when I worked for GM they said one day they were gonna be worth alot of money, (they cost alot anyway)

That is impressive!

I will need to rebuild or swap engines in my B within the next 5 years and would  love to know what are my options.  Is there another thread that details your or other AC owners engine modifications?

I believe ALL of the Allis-made gas engines, both the small fours (begat of the B/C/CA, and also the WC/WD/WD-45/D17/170) are all 'shaft-style'.

It would be more accurate to say that the AMC and GM designes, were derived from early industrial/Ag engines.

Allis used the rail-mounted full-pressure-lubricated overhead valvetrain, as well as pressure-lubricated main, rod, and camshaft bearings, used removable wet-sleeve cylinder liners in cast blocks, with inverted hemispherical combustion chamber, multi-stage air filtration, (what people now refer to as 'reverse-flow' cooling and a myriad of other design principles.

This occured in both the small and big engine as early as the mid '30's... features that automotive manufacturers didn't do until DECADES later.

Industrial/Agricultural engines have always been, in terms of development and testing, far ahead of automotive.  It's a much less forgiving application.
