rtstrack 427 cammer are maken over 700hp with a little work. Depending on if you own a FE block in the 390-428 family, you can bolt on a Dove cammer kit for 13,000.00 plus machine work. I will not give you the life span of this motor because of way TOO MANY MOVING PARTS and issues in the past withthis company. Next Kasse shotgun motor based on a 429-460 lima block. With his setup of upper end in a street motor 820-840HP. Price for the special heads, intake, rockers and misc parts, about 15-17K. The winner of the mess in Ford blue is a windsor stroker with a 393-440 cubic motor you are in the 600 HP and about 11-13K depending on heads and intake. It's all about the WOW factor when you open the hood.
If you are not a pruist on your car than an LS2,3,7, or even building a 9 will be about or little less than the Fords. HP in this motor can go from 300- 800 depending on setup. Price is in the 10-15K range.
They are all about 18-27 dollars per HP. depending on the price of parts and if you want to use, used parts on your motor. Everyone here wants to get the most bang for the buck in both the WOW look and trying to save a little money when possible. I will say this,in the long run, THERE ARE NO SHORT CUTS OR CHEAP MOTORS THAT live long under abusive driving. You will get what you pay for in the deparment. The 3-5 major motor builder here are giving a real solid deals on there motors with warranties and stand behind them. Again they KNOW you are going to abuse the car down the road, 98% of the people do.
