no specific price attached for a fellow wood gassier, would depend on someones distance of travel etc. don't really want to post any specific price but it will be far less than what it would be to purchase the materials alone
This is not a perfect unit and there are several things that I would personally change/would not do again. I am not a fan of flanges, now all my connections are either with turbo hoses or rubber hoses depending on the temperature of the gas they are carrying. This gasifer is quite tall It sticks up by 12inches past the roof line on a 1500 series chevy/gmc. It has a side clean out (which I much prefer) however It does need to be reworked/regasketed or redesigned as it is not the best design. I now use a silicone 4inch (or larger) turbo hose to connect a metal cap which is a nice quick mechanism.
I had it running on a 5.7L SBC 350 would probably be suitable up to a 454 big block or equivalent. It has a 22 inch long firetube compared to the standard 18inch tube.
The new firetube essentially cuts the weight of the firetube to a 1/3rd or less compared to a traditional WK design. I estimate that this firetube (alone) weighs near 300lbs whereas the newer type weighs less than a hundred and can be lifted without use of a hoist etc which is nice for disassembly ect. the newer design is still being tested but so far so good, I have put down sever thousand kms on it both highway and city driving.
thanks for your interest
