Who runs a R302 on the street

[90GT398]

both are siamese, the strong point of the Dart block is it has what is called "Billet Splayed" maincaps which I guess makes it stronger, I always been under the impression a 4-bolt is a 4 bolt but some manufactures word things differently to sound better than the competition.

You can't go wrong with either block, but you can get a bigger bore with the Dart block, than a R302 block, the Dart is capable of 4.185 bore I think the max on the R302 block is around 4.155.

Now when you get them sonic checked, x-rayed and the full blue-printing who knows how big both can go.
