supercharged 347 or n/a 408?
Well after some research and asking around I am a little scared of building a supercharged 347. I have been told the block splits or becomes very weak at about500-550 hp. Now owhen I first wanted to build the 347 boosted my goal was only about 450-500 hp. After looking around I have noticed these are pretty low numbers for a supercharged 347. Though I would love more power I dont want to risk block failure. I was going to buy a short block from woodsy and maybe get the early castings block. Though I would have to spend alittle more money to run the block I have heard they are stronger. Plus I dont have the extra money for a aftermarkeyt block. I will not go n/a on a 347 either because they are just not in the power range I am looking for unless you spend alot.
My other thought was to just get a 408/418 stroker n/a capable of a nice shot on nitrous. I am on budget of about 6-7000 so I dont have 10k for a motor. I have 10k for motor, tranny, and rearend. I have done research on 408-418 strokers and they are alittle on the expensive side but if it comes out about even with a build supercharged 347 then I figure I will go with the 408-418 simply b/c I have heard they are a little stronger.
I guess my main question is what is suggested to go with money wise and performance wise. I figured a supercharged 347 would be cheap and easy hp, but after hearing about the block spliting I am scared. Like mentioned my goal is 450-500 rwp on a raily driven street/strip car. If I go supercharged I was wanting to run about 12-15 pounds of boost. I figure 500 hp would be pretty easy to get with the 347. 408/418 I have seen a variety of numbers both impressive and not impressive.

Crate engines tend to be pretty expensive. Tend to be abouve 8k for a engine in my power goals. I was just going to do all the work myself. Cheaper and a nice learning experiance. But then again I have only looked at dssracing and ford strokers. Ford strokers is the cheapest but still more then I would like to spend. I wouldnt mind going supercharged though. It would bet me into my pwer range very easy I believe

power wise I was at first wanting 450-500 rwhp, but since I forgot about a 377 or 393 I figure 500 rwhp on a supercharged 377 or 393 would be pretty low. So a guess a minimum or 500 rwhp would be a good start.

I think you can buy the stuff from him and assemble it yourself for alot less.

Pretty good deal. I will shoot him a email and see about them sending it un assembled.
Here is one that would do it but it is $7800 408 515hp. http://keithcraft.com/ourengines1.html
