how bout you buy a shell...then take the extra money buy a swap and you will have money left over than you can put that in the motor and you will know whats in it and how long it will last...for example...buy my shell for 700 bux buy a swap for 700 with everything you need thats 1400 bux then put the other 1,800 in the motor...or buy my shell for 700 and buy a bare block and a bare head and all the rest of the shyt you need for the swap and then dump that extra money to build them with aftermarket shyt and spend a total of probably about 3500 instead of 3200 and you know for a fact what you have...just a suggestion...
