you sound alot like me. changing your mind about what you want ( combination wise)

first off it sounds like you want a somewhat street car but dont really need it for daily purposes so you can go a little bit crazy. Do you want boost, all motor, or both me and bugmans favorite all motor with a "little" bit of spray. Nitrous is very safe if done right but alot of people dont know what the **** they are doing so they do all sorts of weird **** with timing and fuel. this might help you out for as having a fun street car then turn the bottles on to blow down the drag strip or what ever pulls up at a stop light. If you do nitrous get the Digital 6 box from MSD it retards the timing when the nitrous setup is on automatically so you dont have to fiddle with the timing when the bottle is off or on.

if you want inches like most guys do.. just do a cleaned up 351. a .030 351 with a better bottom end wont cost you an arm and a leg but will be damn stout and can get a little more torque. in all honesty theres some bad ass little 306's rollin around so its not always about how many inches.its about the combination! i cant stress that enough.




the biggest thing is.. do you REALLYY have 10-20k to spend? because it wont get you any brownie points with us throwing dollar signs around. trust me some of us can throw more money at our cars than we know what to do with. but that doesnt mean anything. also, this comes from my road racing background. Id recommend you building a car that you can build off of later to go faster. get a good foundation with a cage and suspension, brakes, etc. so that as you personally get faster so can your car.

sorry its soo damn long.

Yes I will have that amount in about 6 months when my bonus check comes.
Ok so a 306 is a 302 bored over? So that mean you bore the piston walls to make them bigger and put bigger pistons in them? Im leaning more and more to the 302 just because it seems like butt loads of parts for them are everywhere.Also Ive heard of people and N20 blowing up their engine but I see your point "IF" its done right then it can be great. So would you favor the 306 or the 331? Is there a way I cna find out hp and tq on the 331 and 347? My cousin has a 88lx and he wants to do the 331, so thats why Im enquiring about it now. One more thing if I found a shell that used to have a 4cyc in it and I go and put a v8 is there going to be a problem? Meaning the suspension it came with and other things. Also this question has not been answered unless I missed it. IF I went with different motor, like a 351. What computer would I use?
