This is for street driving basically?
I used a 10" for the street and it really wakes it up.

not sure what kind of use you're looking for in your car, but I'd recommend talking to Kenny at PTC. Since Continental went out of business, he has become a good source for Pontiac converters and can build a high quality converter for whatever your cars specs and usage are at a good price. I had him build a 10" converter for my 455HO and also bought a Continental 13" Pontiac Special before they closed and ended up using the Continental. Sold the PTC converter still in the box to another forum member here for his Firebird.

I have high stall with my HO and like that route with a cammed engine. It does change street manners. It will get you in the good part of power band for performance.
