I recently purchased an 85 Scottsdale 4x4 Half ton. The truck currently has a 305 with and Edlebrock 650 cfm 4 barrel on top other than that it's completely stock. Previously I had a 99 with the 5.3 so I'm used to having some get up and go that this 305 just ain't giving me. So I've been looking at buying a new crate 350. I looked on Gm Performance and found a 350 that has been beefed up and makes 290hp. So I called the closest dealer and was talking with him then he informed of another engine they have it's a 350 HO turnkey. Meaning that bascially this engine's ready to be dropped in. The other 350 would require some assembly of parts. Since this truck came to me without the CAT I plan which ever engine I get,to put headers on it and run true duals with Flowmaster 40's running out the back and I plan on using the same carb unless I get the 350 HO. The 350 HO puts out 330 Hp. Does anyone have any experience with either of these motors? Also I'm going to have it installed my motor swapping days have been gone for awhile.
