Hey there...some know..some don't. I got a 85' K-10/4spd./6in. lift/35's/front detroit lockers. Here the deal is...It currently has the stock, worn 305. It's giving me trouble here and there. Here are my options. I can rebuild the motor, throw on a edelbrock intake, and a nice 4bbl for around $700(I currently got the 2bbl stocker).Or I got offered a freshly rebuilt 350, summit intake, holley 4bbl...and some other goodies for like $600 and my crappy 305. These quotes are from my friend who is a mechanic. What would ya'll do. I'm thinking the 350. My 305 is junk..along with my carb and intake. Hell, if I put a 350 in myself i'd prolly give that 305 away. So...im saying it's a go. I also have a set of NEW dynomax blackjack headers i'd throw on..welded to my 40 series flowmasters out to turndowns(no cat.), along with a NEW Griffin Radiator. So...get back with me on your opinions..what ya'll would do. Oh yeah, my truck is a daily driver, and weekend wheeler. I pull nothing...except a 5x8 trailer every now and then....and I don't get into the throttle too bad. So...give me some ideas!
