Forged Cam Chaft vs Cast Camshaft. Better bearings, etc. B230 FT was nice but if you intend to drive a 242 Group A flathood like it is supposed to driven, you want the B21FT. Also the B21FT block can be bored out more than the B230FT. Install the Big Bore Mahle piston kit from IPD and that puppy becomes a Greyhound!

I have a set of IPD 25mm front/rear Swaybars and the Firewall to Strut tower braces plus a custom made Strut tower brace if you are inetrested.

I used to rally 240's back in the day...
