hey everyone! im new here. im working on a 350 for my 83 c20. right now the truck has a 305, it had originally. the block I have is an 638 four bolt main, one piece rear main. I want to rebuild this with lots of bottom end torque in mind... im not so sure I want to make it a 383 im on a shoestring budget, im 17 and have a budget like a 17 year old. the motor has dish pistons with 4 valve reliefs, and I have a set of 991 heads for it. I have been looking at the kit summit racing has for $237 that comes with all the gaskets and bearings and flat top pistons and thought that would be a good way to go, but didn't know if there would be a big improvement to those flat tops from the original dish's. I was thinking something like an edlebrock performer intake would be about right. I have some longtube headers to put on. I also was planning on like an rv cam kit from summit but I don't know what kind of specs I would want, my tranny is a 700r4. prolly gonna use a good quadrajet if I can find one (possibly one from a big block) or a 600 or 650 cfm carb of some sort if I can find a deal on one. let me know what you guys think, my truck doesn't need to be a hot rod I just want good improvement from the 305, and I live in a hilly area. in the near future I may have a trailer for cars and antique tractors... who knows but but im sure she'll see a trailer or two
