grumpyvette Posted September 19, 2008 Share Posted September 19, 2008 yes I was young once! yes IM still broke most of the time and yeah! I can,t dump buckets of cash into any project so I know exactly where your comeing from, wanting to build from whats available, between the fenders... you can,t expect to throw a mild upgraded,mid durration cam, an intake and a larger carb on the combo and get near the results, you would with a 350,yes you can mildly port the current heads and gain a few hp, adding a cam and headers will help, below youll find some tech articles on building a 305 sbc, the one thing youll find in comon is that it takes a good deal of time and effort, for that 305s , 3.736" bore x 3.48" stroke and reasonably expensive parts to exceed 325-350 hp with a 305 sbc, if your not using nitrous. the truth is your working at a serious dis-advantage with the small bore size and the valves that will clear the clyinder walls at higher lifts....if you put the same money and effort into a 355 or 383 youll see much better results now that doesn,t mean it can,t be done, but your basically starting the hp race with one foot nailed to the floor.so as long as your aware that your at a disadvantage , read thru the links why do I point that out? because its usually not all that difficult to find a decent 350 core to work with, your local bargin trader magazine or the classifieds will usually provide you with leads to cars or engines that need repairs or assembly that have been sitting around, I picked up a 454 bbc suburban with alot of rust and a busted trans for under $400, so theres deals if you look around, I think you can find a basic 350 to build and swap into the car as a starting point, for under $300, momey well spent, and yes it might take a month or so to find at a decent price, but in the long run youll be way ahead! http://www.hioutput.com/tech/343hp/343hp.html http://www.popularhotrodding.com/enginemasters/articles/chevrolet/0667_phrs_305_chevy_engine_blocks/index.html http://www.chevyhiperformance.com/techarticles/148_0502_chevrolet_305_ci_engine_build/index.html http://www.chevyhiperformance.com/techarticles/148_0409_chevrolet_305_ci_engine_build_ii/index.html Quote Link to comment Share on other sites More sharing options...
