I'll probably be flogged for this, but 318's are probably more common in Europe, just as they are here on this side of the pond. A cheap (free?) 318 with a stroker crank installed is 390 cubic inches, no slouch & should rev up quickly just like a 340. And it can be dressed like a 340. Given the rarity of the car and it's collector value, you should long term look at finding a correct '71 340.

I don't get all the " the 340 is much more expensive, so build a 360 statements". Fact is, if you look around at all, 340 blocks are easy to find and rarely more than 600-800 dollars. Even if you find a suitable 360 block for 100 dollars, in the whole scheme of the whole motor build you have maybe 500-700 dollars more money in the 340 build( cost difference of the block) Many times you can find a 340 short block with steel crank for not much if any more than the price I stated above for just the block.... Needing rebuilt. You pick up the quality steel crank that can take a lot of punishment and is a nice piece. For a car like yours, for very little difference in money I would i put another 340 in it( or a stroked 340)/416.... No brainer Edit.... Didn't notice I hadreplied to this thread months ago.... Lol

Not argumentative, but I've heard there was a problem with valve shrouding when you when with larger valves. Something about notching the cylinder wall tops. Can a 318 breath well enough to make power with a stroker crank?

I think the carb and intake manifold are different between '70-71. '70 still used the square bore AVS, and '71 was the first year spread bore Thermoquad? And I think the '71 was a one year carb before an improved version came in '72? Someone check me on this, ScottSmith Harms?
