Hello Ervin .
Sorry to be so slow getting back with you . The computer has been down sense yesterday morning and just got a repairman out to fix it.
The full size 318 ram will work OK , just not as well on the road as a dakota . You can expect 50-60 mph on the flat road.
Below is the building link for the 94 ram that I built. I drove it to Argos about 4-5 years ago.
My son was using this truck for school and I set the gasifier of temperately and have not put it back on yet .
I had an oversized gasifier but if I put another gasifier on it it will be a 12 inch just as the dakotas and my V-10 ram.
