What woud you have?

 

402 LS2 aluminum block...

 

408 Iron Block...

 

i chose 383 because i am poor.

i believe i could stroke my current motor a lot cheaper than i could get a 408 setup, not to mention the supporting parts needed.

plus i really like rpm

 

I am very happy with my LQ9 402. TSP.

 

my HPE 408 is a freakin animal, love it. cant imagine what it will be like with heads. I was going to get a 383 setup originally but the 408 was the same price so why not?

 

L92 with a stock crank and rev it to 7000.

 

408 iron block

 

damn you and that L92 hurry up and lets pull the motor out and start on your car son!!!!!

 

I looked at both and settled on 370 for budget reasons

 

Bingo

 

yup

 

Maybe with the sleeves and raised deck for a nice 500 CID LS2.

 

iron > aluminum

408 > 383

spray the world at the 408 and destroy peoples day

robb

 

iron = heavier BUT STRONGER

 

iron 408 is cheaper than alum. 402

 

which setup do yall think is more reliable? what is the price difference in the two? ive been looking into a genIII iron block

 

408 iron block. Once I get the 346 built I plan on swapping over the heads/cam/intake. Price? Come on, it's only money-it's purpose is to be spent. There is just no replacement for displacement, well, I guess there is boost. But you can boost the living **** out of an iron blocked 408 compared to the aluminum 383.

 

434 darton wet sleeve block!

 

N/A? Boost? Spray? Street? Race?

Solid roller 427.

For a typical street N/A engine 402 aluminum is the way to go. Like an aluminum block isnt strong enough for that
