BHolm said:So it IS possible my car dipped into the 11's(barely). I do still run iron heads and they are ported but not all cut up and welded. My intakes flow 275 and that was enough to make 525hp and 560 lb/ft. I was enough to push my full weight GS to an 11. 97@117 one day last summer. I run it in a street class, so that is why the Drag Radials. I agree there are better choices. I have probably 100 passes and 3000 street miles on them. I actually find they hook on the street pretty well with my mostly stock suspension (no-hops and airbags). Regular radial TA's just burn up on a street launch. Never seen a DR wrinkle, seen a bunch of them though. Oh, that time was full exhaust too, nice quiet Walker long case dynomax.
I found the cost to do the Buick wasn't much more than the Chevy's, maybe 15-20% more for the same power level. The 455 Buick engine also weighs about as much as a small block and has enough nickel content in the heads to not need inserts for the valve seats. It has its advantages. Granted the next bump in power will require a girdle for the block but any faster and it will require a roll bar. I didn't want to do that because it is a street car.
Thanks for the tips though, hope I didn't run up too big of a bill.
The Buick's were a good sleeper engine if you didn't push them too hard. Light and made a ton of torque. But if you start to spin them, they will come apart if you don't invest some big money. 11. 97 is a good number, but 117 seems a little soft, like its nosing over. I'd figure you should be in the 119 to 121 with that ET.
