i like this were all fighting over what to do, and what engine steup will be the best. in response to the person who wrote why olds power why not sbc or 455, well i can't find a 455 in my area for a decent price and to regards to sbc are great engines but it's a porven fact olds engines are built stronger and can handle mo than sbc engines!
hahaha just read around man ! and after you have the exerience i have with cars and motors then we will talk again. but besides that i am done teaching the deff and blind.
there are differences in everything yes a fwd and rwd are both cars but they are different. yes chevy and ford both make trucks but they are different.so the same thing goes for a N/A and boosted motor but belive what you want.
and every motor has limits the 307 is not your best option but can be build to make desent power but is limited to the 300 mark.and it is not the most cost efective build by no means.bottom line is that there is no replacement for displacement.

Look man, you're talkin to people who have done this before, take some advice. If you're bringing in 100 grand a year it wouldn't matter if you built a screamin 307. But I'm guessing you don't. When you say things like "It's a proven fact olds engines are built stronger and can handle more than sbc engines" it exposes you're green. Any engine can be built. Hell, you can make a 3,500$ 350-400hp 355 if you want. Doesn't that sound better than 3,500$ heads for a 307?
I rebuilt a 307 with a similar kit you mentioned at the beginning of the thread. It wasn't worth it, a complete waste of 1,000$. You need new pistons, all new machine work, etc. You're looking at 2,500$. You'd be smart to save the extra grand and have a nicer engine with some real power.
ya i hear you but my engine options are kinda limted, i mean i can't find them where i live and not much people are will to haul the engine to me .

Here's what I'd suggest - call around some shops in your area - mechanics, dealers etc. Ask them what machine shop they use. If you get a few answers that are the same, chances are that shop does good work for a nice price. Go talk to the machine shop and they'll help you with everything, all your goals can be met. They usually have old blocks sitting around they'll sell you for dirt cheap.
You might look at getting a 350 block bored 30 over, the whole machine work + price of block might set you back 1200$. The 350 is easy enough to put together, if you know someone who has done it before ask them to help. Or you can have the shop build the whole thing, but it's much more expensive.

Dumb *ss.....
If they are SO different,tell me why my turbo Grand National has all the same parts besides pistons as its NA brother???Block,rods,crank,oiling system,camshaft,heads,EVERYTHING.
There is a replacement for displacment,its called boost.
When you add 14.7 psi of positive pressure to an engine,you have effectively DOUBLED the cubic inches.
231ci + 14.7psi(not atmospheric pressure) of boost= an engine that produces the tq and hp of an engine roughly 462ci,and they move the same amount of AIR.
Why do you think cars slow down at higher elevations?
Im no internet guru talking out of my *ss,5 minutes of searching on google will confirm everything ive written....
no that would be you !
and as for your buick it's called boosting on a buget.i did it to 3 3400 with good results.
and i still stand that there is no replacement for displacement because if i boost my 468 bbc do you think i will not S%%^ all over that 3.8 ??
i was just stating that you can compare a N/A motor to a boosted app .
and if you dont understand that it's not my fault.
bty this is not helping the og poster anymore so respond in anyway you want i am done.
peace
