Rich with a 460 in it you should be able to hit the mid 11's on just engine and no N2O . the 521 crate engine is a fast one for yo it should be in the low 10's with it...easy... or quicker

I'm not really sure what all this means, but for 10 grand I would hope its top notch stuff..

 

Rich depending on the weight of your car it should do you well, 580 hp should get yu in the 10's real easy... do some looking in the Auction block and you may fine one for a good price...

I think a 521 with around 600hp can be built for less than Ford Racings 10k price tag with some careful planning research and patience.

hopefully Ill be around 8k total with my 521 and pretty much everything is new.

I had the opportunity to buy several really good short blocks and pretty much complete engines but it always seems some particular part just isnt right for my build. In most cases its comp ratio and my need to use pump gas with 72cc heads.

 

Give Carl a shout(cars by Carl) builds nice stuff at a fair price. 8)
