blocks strength

[stocksnake]

i need to no which block is stronger between a 99-04 gt cast iron block or a tekside block both being built correctly. trying to settle an agruement with a friend any help would be welcome.

btw it would be going into a street/ strip car with 500+ hp

teskid, cobra crank, manley rods, and some forged pistons

[Boosted4V]

Teksid alllllll day long. Its been in the 6's at 200mph and 1500-2000hp

[stocksnake]

Thanks that is what i have been trying to tell him. Since he is more into the old school suff.

[smith876]

....and some forged pistons

but certinally not all 8, just some of them :smilielol:

It's not that teskids are stronger which I don't think they are. But teskids CAN hold ALOT of power so they shouldn't be a reason to shy away. Iron blocks are strong as hell too but you get a slight weight penalty with them. However, they are cheap and easier to come across. Other blocks to consider are Lincoln Navigator blocks, Mach 1 blocks, 99 cobra blocks, all are aluminum but not teskids. Teskid is the strongest alum. block

[Boosted4V]

99 and even early 01 production cobra blocks have been reported teksid. The Aviator blocks are strong too, just not as strong. And Navigators are 5.4

[Buford]

You are correct - Aviators are 4.6 and navies are 5.4 I messed up

[stocksnake]

would it be hard to put a 5.4 4v in my cobra

[Boosted4V]

Its not impossible but it takes some work. It takes a 5.4 based shortblock, you can use any 4v C head but with the increased deck height of the 5.4, you'll need to either run a 5.4 intake which creates the problem of hood clearance or they make adapter plates that go between the head and intake that allow you to attach a 4.6 C head intake.

[stocksnake]

ok but would the performance gain be worth it in the end of it

[Boosted4V]

You'll gain some bottom end torque but most people are just fine with the 4.6
