Well the 272's would be less lopey, but you will be able to get the most power with the 280's. If i were running your setup, i would go with the 272's they will be better on the street and keep your idle streetable

9 out of 10 probably would agree 280's are not meant for a street car and to stick with 272's.

272's (I don't care about idle or power in the sub 5K rpm range, I have 280's)...

I kinda tought the 280's were a little to big. Thank you all for the input, guess i have a brand new set of BC 280's still in the sealed box for sale if anyones interested. I had bought them thinking i was going the 2.3 route, but after all other things could not afford the stroker kit. Thank you all for the info and hope i don't lose my shirt selling these

What do you plan on reving it to? I can't believe no one asked that already... If you're looking at an 8,500rpm or higher rev limit, keep the 280's.
