max stroke ??

So making a 434 is out of the question with a standard block then.



what would you go for?
1. 3,75" making it a 406 cid
2. 3,875" making it a 420 cid
3. sell it and go for a dart or motown right away?

If I build it, should I go bananas eg. all forged H-beams stc or just cast and some nice rods and pistons and make a cheaper one?

Depends on your power goals. I went with the Dart block to save problems when I decide to up the power.

Stock block can be modded to live at 550 hp or so. in the long run its better to start with an aftermarket block. you can spend 1000.00 building the stock one or spend 1800.00 on a good aftermarket.
