Block Questions
Im currently looking into supercharging my TA. Iv done some research and have found that the 98 blocks are weaker than the mid 99+ blocks. The blocks themsleves have reliability issues past 550hp. I hope to be around or slightly above this eventually. I like to mod ahead of time instead of having to go back and do things over (wasting money). I have been looking at Cast Iron blocks but there are so many out there and I dont know which ones would be best to work with for a supercharger. That and I see alot of people are having problems with some of these aftermarket companies coming thru or the quality of their products not being up to par.
Any suggestions on a good company to go with or what kind of crate engines I should take a look at.

get an older 6.0 iron truck block, I think the ones are aluminum. I've seen the 6.0 truck blocks handle 800-900 hp.

Stay away from SLP.
With that said...there are many great companies build you a iron block 402/408/427 for under $4K......search around with our sponsors....research...ask for references...goggle the company.....ask for the warranty in writing....dont settle for what is posted on the INTERNET as that can change in a flash....I am having my 402 custom built...choosing the parts individually.....more time consuming....but what a dependable beast we end up with.....and yes for a tad over $4K I get the components I wanted versus a "package" deal.....

I worried about the same thing. I am building an LQ4 Iron Block. I have a D1SC Procharger with a 15lb. set up. Everyone recommended this block due to its strength. You can get one from gmpartsdirect brand new for around $600.00. The part number is:12551366. Good luck.

Good luck. The 6.0 block could be made to a 402, 408, 414, etc.

If you don't mind staying at the stock cubes, then check out the engine girdle available. I have seen them and they used it on a high HP vehicle at Exotic Performance Plus on a TA. Look at the featured cars section. It has pics and explanations...........see what you think. Otherwise you will take the weight hit of the iron block, but in the end it is your decision.

Ill read into it.. I have just learned thru the expirience of others that shortcuts just delay the inevitable. Sure, it will hold up.. but for how long. And why risk it when you could do it the right way.

there is nothing wrong with the stock block. concentrate on your fuel and tuning systems. detonation is whats going to kill you. plus dont forget about the extra 80+ lbs that the iron block adds over the aluminum.

So....with this new motor..said goodbye...and fuck you very very much.... to the previous shop and changed shops/dyno's and tuners.....also changed AF gauges to a much more accurate wideband that we monitor from the a-pillar....I guarantee we will have proper valve clearance this go around.....
with all that said....I think the valves and the AF were off a tad...not much...and probably contributed to the early demise of the motor...but the main factor was a stock bottom end and a shitload of power caused a rod bolt to break and kaboom...
With the new motor we are also installing a Walbro pump and the bucket mod along with the BaP.....not that we had any issues before...but now we will be putting down even more power and $300 bucks is cheap when you look at the big picture...so yes...I think the AF and head install of the previous motor was out of whack a little and contributed somewhat to the death of that motor.....we wont make those mistakes with this one I assure you...
