ERA 535 and/or TURK,
Did you guys find a source for the 3 1/2" flanges and elbows and have you have you tried out your new mufflers???? Cripes, I haven't even got my car together yet and I'm finding new modifications to new parts I haven't even used yet. I'm hoping to hear about huge horspower gains from those big blocks.
Take care, Steve D***ey
