Just me, but, I would not buy a stroker in kit form if I were going to spray. For one you are wanting to make 700HP total. It can be done but, you can't make any boo boos or your block will go crunch clunk.

One good option you might want to look at is dealing with your machinist on the parts. Often he can get a better deal than kit suppliers and you have more options when he is putting it together ( the parts that is ) for you. I am putting together 700 HP 408 blower motor using a stock 360 block. The block sonic tested good. half filled, Milodon steele 4 blt caps, Scatt forged crank, Eagle forged H beams, Icon blower pistons. I got a better $ deal from my machinist, than a kit supplier using basically the same parts. Another plus is that your machinist has more of an investment in making sure the parts are matched correctly so it will live.

You usually get the same HP with either stroke and the bigger the stroke the lower the rpm it will happen. I like that you can make the same power at more reasonable rpm levels. Just my Keith

Still not as hard on parts as a real high rpm stock stroke engine would be,the valvetrain is more stable due to less rpm. Biggest killer of engine in my opinion.

You're right but think about it like this.. Let's say a 4" stroke makes peak power at 6500 rpm that's 72.2 ft. per sec. Now put a 4.250" stroke in it ans say it makes peak power at 6200 rpm, that's 73.2 ft. per sec. Not much difference huh. Will also have more torque to get the car moving. Less convertor and gear needed.
