Tch777,
It is a '75 K5. Bought it in April with a pretty well trashed 350. It had just been recently rebuilt it looked like- by someone who knew even less then I did. All the cylinders were different sizes- bored .062 and up. One rocker was not even on the push rod, I found freeze plugs that had just been pushed into to the block- and the list goes on.
Got a different block- bored forty over, replaced everything between the intake and oilpan. Put in an RV cam-don't have the numbers here. Also put new heads on. Has a Wiend (sp?) intake and a Edelbrock Performer 1406 on it. Next weekend the offroad needles go in that. Topped it off with a K&N.
Flowtech headers are in back waiting to go. This winter a six inch BDS lift is going on with 36 Swamper TSL's or 35 inch Boggers. At the same time a 14 bolt with a spool is going in, and a eight lug Dana 44, both out of a 3/4 truck are going under it. Putting on ORD greaseable bushings and front shackle, as well as a steering brace. Have to start getting all the parts on, my buddy is getting sick of stuff laying around his house. /forums/images/graemlins/whistling.gif I have to get a garage!!!
Other spec's- TH350 and 203. Need to find a 205. I have been waiting for three years, saving money and wishing for an off-road truck. Hopefully, I won't be disappointed when it is finally to the point where I can go have some fun. Couple pic's in members rides from the day I got it- search with username odoa3.
