"I've got a big Lakewood steel bell in my Roadrunner that I bought new in like 91. A Browell slant back bell in my race car. Are the new aluminum bells SFI? and they actually have one for the big flywheel?"
The new lakewood aluminum bell can accept 10.5 or 11" flywheel. It is also drilled for multiple type transmissions and includes adapter rings for the bearing support hole depending on what trans you bolt up to it.
I dont think it is SFI rated.
