So, I am in the beginning stages of pricing out my 4.6 build. I have a KB 2.1 installed on my stock 96GT engine running 9psi. I am looking to build a motor to hold around 550rwhp on the safe side @ 14psi. I truly do not ever see myself needing more than that, as the car has still never seen the track, and is mainly just a weekend warrior.

So here is the question, should I build a teksid block with a forged crank, rods, and pistons or should I run the 4.6 cast block, cast crank, and just add forged rods and pistons. From what I have been reading online it looks like the cast crank and block should be able to hold the power pretty easily, but I want to make sure it is the way to go. By not buying the forged crank and teksid block, I would save around $500.00 which I could use somewhere else.

Teksid for sure. Cast crank at those power levels is a ticking time bomb.

So you think the teksid block and forged crank is the only way to go, or could i use the cast block with the forged crank?

I know it may seem retarded that I am trying to save money with the parts I already have, but every little bit helps .

your stock block is 100% fine. even your stock crank would be fine for 550. but i wouldn't use it id go with a forged crank. 100% fine with the stock block theres no need for a teksid

Completely agree. Your block is fine just go/$$$ for the internals crank,rods,pistons.

Yeah teksid isn't necessary but if it's available for you, go right on ahead! Not only is the block stronger than Arnold, the weight loss is killer too.

Thanks guys for the input. I know the teksid weighs about 40lbs less which would be awesome. I guess if I can score the block cheap I will pick it up. Otherwise I will just use my block and pick up a forged crank, rods and pistons.

Yea sorry I didn't mean to sound like your block won't be safe. Definitely forged rotating assembly though, for sure.
