Just think extra stroke is hard on the stock blocks and there are other ways to make power. Buick had the shortest stroke of the GM big blocks and why throw that out the window and have stroke like a 455 Olds or Pontiac. But...just my opinion.
I've made great power by doing it,and without having an all-out race engine. Runs cool and I can drive it.
Don't know what "great power" is but I have a 464 , Stage 2 SE, with stock rods, stock crank and hydraulic cam that gotta be making some power to run low 10's in a 3700 lb GS.....and live on the street and track. I bet with TA block though a stroker 500+ cubic in pump gas motor would make more hp ......and live. But that's $$$
The first one was good enough to go 10:90's @ 122,in a 3850lb car,iron heads,full exhaust,drag radials,and drive everywhere,including to the track. That was built in 1998,and was just removed this February to get freshened up,and get put in a different car. The new one made 772/710 on the same 93 cat-pee gas. I added more stroke,and lighter-weight parts,to help take stress off the block. I have Oldsmobiles & Buicks,and Buick has a greater selection of parts,compared to Oldsmobile.With Olds,I have to do it with a 4.185" bore,and heads that don't flow the greatest numbers,but flow numbers aren't everything.Stroking those has become real popular for the street/strip guys. The Buick parts,and what you can do with one,make it a lot easier.
What times is low 10s. We were running 10.90s on our iron head 464 with a 3850 pound car and driver weight. We swapped to cnc te2 heads and sv1 carb. Kept the same short block, 308s, we are about 11.75 compression now. Our heads flow some really good number, 380/270@.700......370/265@.600. Have not gave the chance to get it on the track yet due to 2 water pump motors failing in 2 weeks. But low 10's sounds nice.
