Building a stroker 402, use aluminum or iron block?
I am having a new stroker 402 built for my 05 GTO. I was thinking of going iron for strength, but like the thought of the less weight and staying with aluminum.
Also installing a Maggie 122 OVERDRIVEN, forged internals.
Pro's vs. Con's?

No way I would add a chunk of iron to the front on that car...the f.i. is going to add plenty as it is. How often do you hear of aluminum blocks splitting or failing even at extreme power levels?

Aluminum 408ci, imo. Just get the block sonic checked. Iron blocks are just too heavy imo, and you aren't going to see a strength issue with the kind of power you are talking about.

Ha. Depends what you want to do with the car. Road race and rebuild every year? Then aluminum is the choice. Would also go with billet main caps, as the aluminum blocks have a greater tendency to experience cap walk at high hp levels. Drag and rebuild every year? Probably still aluminum. Want to push 800+ rwhp and have the motor for a couple of seasons? Go iron.
