Well ive decided to do a somewhat detailed thread of what ive been working on the past 4 months. i stared with a tired le9 305 but only 82k on the clock and a th350 swap. someone ditched all the electronics but left the ccqjet on her so she smoked like a diesel and got 6mpg i added a 1406 edelbrock carb and a factory gm aluminum 4bbl intake. it had true duals with 2 1/2 pipes and glasspacks straight out the back. i added long tube headers 2 1/2 custom y pipe and 3in high flow cat with two turbo mufflers dumped under the bed. only gave $1500 for her and i drove it most of the summer to and from work with the 305 so it had some use. anyway after some of my upgrades and repairs the truck still always smoked a little but not constant and held ok oil psi but near the end it smoked more and had more dirveability issues. it started knocking or i should say rattling in the engine not consistant like a rod or main knock and not a deep knock sounded almost like bad flexplate or loose tq converter bolts. i made a deal with one of the members of a f-body club im a member of and we did a even trade for some 17in wheels/tires/spacers that i had been trying to sell for a shortblock he put together for a turbo build. he had reciepts and all and had about 2k in it and a parts list. with a 64cc head it would have been in mid to low 8 compression ratio so i ended up using my stock le9 heads with new springs and a .015 shim headgasket to get me around 9:4.1cr i changed the cam from the comp 268hxfi to a eglin 214/224 444/465 112lsa cam or basicly the summit 1103 cam. anyway.....at the same time the motor was dying the trans started slipping so i ended up ordering a summit racing 6in tailshaft th350 and i added a 12in 2800 stall converter than i had from one of my f-bodys. since my truck already had the swap from a 700r4 i already had the aluminum adapter but found that aparently my old trans wasnt quite a 6in outputshaft so a machiest at work made me another aluminum adapter to make up the difference. i forgot to mention but the no.7 piston had a ringland broken and i assume the skirt ended up breaking off causing the piston to wobble in the cyl and cause the noise. well i finaly got her runnin and have a total of maybe 20 miles on the new setup and it is awsome lol. the converter flashes to about 2200-2400 about what it did in my f-body with the same cam in a 305. its still open headers at the moment and i need to adjust my modulator valve some because it will be in 3rd gear by 15-20mph and the truck only has 3.42 gears so its not too fun in our hilly area. anyway enough of my rambaling here are the pictures and ill try to go in order from 305 in to 350 in and a couple of videos to show some driving and the sweet lumpy idle. :) enjoy!
btw i did about 99% of the swap alone and in the yard lol
