i am considering getting an aftermarket block since my goals will put a stock block on the edges of splitting if not splitting them. what is it a good aftermarket block that can handle 500-600rwhp with out breaking the bank? i do not need a block that is capable of handling 1500+ since it will never see close to it. thanks for you time Justin
FRPP's new Boss block seems to be the cheapest. http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=9085 or Dart or a World block.
Stock block will hold 1000hp. Its the rods and crank that will break. Blocks break when somthin lets loose in motor.
ya 1000 hp seems high lol i know a guy who made 603 hp on a stock block bored to a 306 had the motor for about a month got on it a few times and then crack right down the middle
We're talking 5.0s here. 450 rwhp is pushing it. 500...its not IF it will split the block, its WHEN. PERIOD. The thickness of the webbing on the front, rear, and lifter valley is very thin. The split will start at the crank bore and go UP until you have damn near a perfectly split pair of 4cylinders...
:rollinglaugh: i am sorry i wish it did man i really wish it did does anyone have any personal experience with them?
well i was talking to my mechanic and hes getting his motor built up and he was explaining all the machining that had to be done on his...its the same thing with R blocks they come rough from the factory and need extensive machining
OOPS Sorry i didnt know you had a 5.0. Ive heard they do split. And i would think having it bored would only make it worse. Not to steal a thread but i was told by my tech that the 4.6 will hold 1000hp ryclef is this true or not?
