That depends what your gonna use it for. Is it gonna be N/A or FI? Give us some more info. The main difference is the weight. Iron is about 90lbs heavier I believe but will be needed fpr some setups. Did you think of any other options? A 402, 408, 427, 454 etc.

if you can afford it the aluminum block is great.i thought and thought about it and finally decided i would go with the iron for the rigidity of it even though an aluminum block could handle more power than i'll ever make.i guess it is up to who you ask how much can an aluminum block handle before reliability becomes an issue.

Go iron unless you have the $$$ to get the alum. LSX block. GO iron 408+c.i.! 100 pounds typically in drag racing equates to a tenth slower in the quarter. THINK about it!

actually i didnt see this one...370 cid iron shortblock.

"Our 370 cid short-blocks include a new 6.0L cast-iron block, factory GM LS1 crankshaft, Scat H-beam 6.125" connecting rods with ARP 8740 rod bolts, and Diamond Racing flat-top pistons with -2cc valve reliefs. We can custom-build your 370 cid for you also using a Lunati, Eagle, or Callies forged crankshaft, as well as with Lunati, Callies, or Oliver connecting rods. Custom pistons are also available for heavy nitrous and boosted applications. Feel free to give us a call, and we will be more than happy to put an itemized estimate together for you! We also keep 370 cid short-blocks in stock, so give us a call for what we currently have available. If you purchase one of the engines in stock, it can ship out to you on the next business day! All of our engines ship via truck freight."...only $2900. i think ill get that. i need to keep it on a budget. building two cars at once is a bitch!! lol
