Guys, quick suggestions/opinions. Karkraft has bare aluminum 5.4 blocks with stock bores for $443. to my door. They also have rebuilt Lightening short blocks for $1895. plus shipping available. They have forged pistons but the stock powder rods and about 9.5:1 compression.
EBay has forged pistons(339grans/rings and forged rods/H-beam called ACE(?) for $788. With the bare block I could get forged rods and the higher compression I would like. However I would need more parts to comlete the motor such as the front cover/crank. I plan on getting a set of heads done whether even a set of the infamous Patriots to one of the better known shops that specialize in modulars. Looking for the ultimate interstate cruiser but I am hard on my vehicles so the forged rods could be a benefit even though the stock rods may be all that I would need!
This is going to be a project that as stated before I want to do correctly from the start.
I plan to do the 5.4 as cash allows and then get the Mustang to the shop and have them do the swap useing as many of the 4.6 pieces as possible.
Right now with the info I have given what are your opinions, bare aluminum or wait and get a short block but never know what they(karkraft) will have as they change inventory constantly. I am leaning towards the aluminum bare 5.3 block myself for the options it would allow and aluminum is lighter and my car is a convertible. Thanks and am sure pleased I found this thread and am even excited as I haven't done a motor in a few years and having a specific goal of as much torque as possible is nice too!
If you need to ask a question or 2 please do! THX, mark
